Hi,
I am deathly allergic to crab and shrimp, and would love to hear from others. I've tried most other seafood and been fine... how do I know, though, if a rare type of fish won't also get me?

just an FYI - Cat scan dye is made from shellfish - from experience and 9 hours in the emergency room after having a Cat scan
8/ 5/08 11:29am
During a C.T. Scan with Contrast Dye I went into Anaphylactic Shock. This happened very quickly after the Dye was injected.
First I was very hot, then I was consumed with pain all over.
I was unable to speak because my tongue started to swell, and breathing became difficult.
I woke up 5 hours later at a different hospital with my Husband and Chaplin standing over my bed.
I was told that many people do not survive this type of incident.
I was never informed that Contrast Dye could cause a reaction.
3 years ago I did have hives after eating shrimp, but since then I had eaten lots and lots of shell fish without a reaction.
So....no more shrimp, scollops, or any other shell fish for me...darn!!!!

I've heard that contrast dyes for medical procedures have iodine and shellfish have a high concentration of iodine. I always list iodine as an allergy along with shellfish. A few years back I had to have a medical procedure done that required a dye containing iodine. I explained my situation and they gave me a high dose of benadryl before the procedure. Even twith the benadryl... I was itchy throughout my body for about a week. In other instances I have refused the dye and had the procedure (MRI) done without it.

Just as an FYI, there is an alternate to an iodine based contrast dye. My son is extremely allergic to shellfish, mollusks, fish and iodine (along with a long list of "environmental" allergies). Three years ago he had to have a CT Scan and the local children's hospital, being warned ahead of time, told us about a iodine free alternative. I don't know what the name of it is, but you may want to look into it. Because my sons ct scan was not pre-planned (we were admitted through the er), we ended up having to wait a few extra hours while they brought in the iodine-free stuff, but it is available.

I had a reaction that put me in a hospital for 2 days from seafood. I was 14 and had no clue I was allergic I had eaten it since I could remember. Since then I have always just avoided it. I was tested last night and my allergist verified by allergy. I can live w/o the shellfish but was curious about other fish (for the last 8 years I have just avoided 'salt water' fish) he told me that most people that have a shellfish allergy do good w/ any FRESH fish (I emphasize FRESH b/c i have found that a lot of packaged fish contain shellfish additives) Be carefull b/c a lot of those are also manufactured in plants that also package shellfish products. I don't have a problem w/ frying oil used to cook breaded shrimp and other things like french fries. I have had a reaction to being in a kitchen that had boiling shrimp. My advice...be careful if you feel wary don't risk it. I have been very careful and only had my initial anaphalaxis, the outbreak from boiling shrimp in the kitchen and one other shrimp problem from a misunderstood chinese restaurant worker...not bad for 8 years!!

I am new to shellfish allergies. I recently started having reaction 24+ hours after eating shrimp. Supposedly this is too long, but this is what happens. I didn't know what the entire body rash (yes, head to toe of little itchy splotchy red bumps) was coming from. I always ate shrimp and remember getting a rash a few time in my life. After keeping a food log I realized that the only time I broke out was when I ate shrimp. So I stopped eating it. The allergist at Kaiser tested me and said I am not allergic. However, I have not broken out until I stopped eating it. That is until recently when I went for food tasting for my wedding...We had ceasar salad (delicious) but must have contained shellfish, because I know have a rash. Ahhhhh! I didn't even think.
So, I guess I am wondering, is there future advice for me. Is there other allergy testing to be sure I am not eating something I shouldn't? Fish doesn't seem to bother me. I was surprised about the dressing, because I only had a few bites.
Thanks and good luck to everyone!

...has anchovies in it. Depending on the concentration, I can eat it too. Had it at Wendy's fast food and fine. The one at Outback makes me awful sick. I have had food allergies since childhood. Smell, taste or touch. I only eat like 40% of the food on planet. It sucks, dating was hard. Thank the Lord my husband is plain finicky or we'd never make it!
No nuts, no green veggies, chicken, pork, turkey, beer, lanolin, fish, shellfish, pencil lead, dust. The list goes on and on! Just have to be religious about reading labels, taking a small bite and waiting to see what happens.
I used to work in a grocery store in high school, got to the point I'd go home sick every day!

I found out i was allergic to crab and lobster when i went to see an allergist to find out about indoor/outdoor mold because our house at the time had a mold prob inside the front walls. I kept getting sinus infections. While I was there, I asked the allergist if she was going to test me for any food allergies and she said, no, why? i told her that i had just been on vacation at hilton head and after eating a crab cake sandwhich my throat started getting itchy and i started coughing. She said, sure, we need to test you then. So, they did a blood test and the results came back that I was allergic to crab and lobster. i told her that i liked shrimp - and was it safe to eat that and she said yes. I still dont understand why its okay to eat shrimp. Thinking back 10 years, I was on a date and ate just a couple of breaded shrimp stuffed with crab meat and had a similar reaction. A few years ago, while in Biloxi eating crab at a buffet, i poked my finger with the shell and my fingers swelled up. So, I've been told to get an epi pen, and I hadn't yet because, I just thought, I'll just not eat crab and lobster. Now, I'm thinking that I should just get one because, a couple of nights recently, while I was at work, my husband was at home with the kids and steamed some crab legs. Needless to say, the water ran out, and the house filled with an awful burnt crab smell. I didn't want to seem like a hypochondriac, but I know that my throat got itchy. Do I ask him not to cook crab for himself anymore or does he just need to not smoke up the place? Anyone know anything about this?

I know for certain if you are allergic to crab/lobster, that you will get thee same effects from shrimp. But keep in mind this has to do with saxitoxins which buildup within crustaceans. Those are all crustaceans.
You may or may not have an allergy to mollusks, clams, oysters, abalone.
Epi pen is always good to have. Allergic reactions get worse over time.
6/ 7/09 12:34pm
Wow Same thing happend to me last night. The only thing is it didn't take 24 hr. to start. I started itching all over. Then a rash broke out on my face,splochy red bumps. I only ate one shrimp,and two crabs. This is not the first time this has happend. Maybe about 2 months ago. I ate some eggrolls that had crab meat in it. I had a bad stomach ache, itching all over. Rash on my face. No More seafood for me. Never had problems when I was a kid.
7/12/09 8:50pm
I think I too am allergic to crab and lobster. Three times in the last one year I have had crab or lobster either on its own or some part of it blended into the dish I'm eating and I have had severe diarrhea within 30 minutes of the end of the meal. Its almost like clockwork, I feel my face turning white, my stomach starts bubbling and I immediately have to go to the toilet.
I never had this problem before, I'm 39 and this just started happening in the year or 18 months.
8/ 7/09 6:40pm
In regards to your last statement I disagree. I'm allergic to crab and lobster but can eat a whole tray of shrimp, my favourite, without any problems. I have been craving scallops but am not sure if I'll react. My husband and I are going down south and I want to try crawfish. I'll be getting a perscription for an epi-pen before we go.
8/17/09 6:22am
Anonymous was correct. I too am allergic to crab-lobster starting at age 29.
Every other kind of seafood I am fine with. I have tried crayfish in small amounts
with no prob. In fact, I'm getting ready to go throw my crawdad traps in the pristine
waters of the Alsea river not far from where I live.Site of some of the best crawdads
in Oregon. By tonight I'll be savoring those little lobsters with a fine vino.

Just reading your stories, and thought I'd share mine too. I grew up eating all sorts of seafood and never had one problem. This is up until last february, we had a lobster dinner and the next day, about lunch time I went out to grab a sandwich and by the time I got back to the office I was covered in large pancake size hives all over by back and stomach. They slowly dissappeared working their way onto my arms and legs and face. This happened on a thursday and a I finally went to the doctor the next Monday when it hadn't gone away yet. I had been takin benadryl but it wasn't doing the job, so the doc gave me steroids and a topical cream. I wouldn't normally like to take all these drugs, but I happened to be flying out of the country to get married the next week...and did not want hives!!! Everyone thought is maybe was just my nerves, but I wasn't stressed or anything. So since Feb. I have had shrimp, calamari, ceviche, lobster soup, scallops etc. with no reaction. I started to think maybe it was my nerves....until this Christmas Eve, I had a crab dinner with my family, and didn't really think anything of it because of all the seafood I had ate since the breakout. Sure enough Christmas day around 5pm I started to feel itchy around my mid-section, I went to look in the mirror and had the same big patches alll over my stomach and back. It is now 3 days since I have ate the crab and I still have the hives, mainly on my face now, so I am guessing they will be gone soon. Does anyone have any thoughts to why I would randomly develop this allergy? I have no other allergies and eat almost everything, with no problems! So annoying!!! Would love feedback!

I developed an allergy to lobster around the age of 30. I am absolutely terrified about trying crab now, but I can still chow down on as many shrimp as I can handle. My lobster allergy is on the severe side. Everything freezes up on me regarding my respiratory system. My throat swells to the point that I can't breath, my chest contracts as if I had an elephant on it and my eyes completely swell closed. Not a pretty sight to say the least. I recently bought some imitation crab and lobster meat, but I'm holding off trying it till I get a new epipen. I always get pre-medicated with benadryl and prednisone before I go in for any MRIs that involve the iodine based dyes. I wonder if I can get pre-medicated for a nice lobster dinner as well? I can dream, can't I? I do wonder why it is that I can not even think about eating lobster, but have no issues with shrimp at all. After reading a few of the posts on here, I do know that I will avoid crab as well.
9/12/10 3:53am
I am the same way. I am severly allergic to crab & lobster but I can eat a few shrimp and be ok. Although one time a while back I had a really nice salmon dinner and I got sick from the salmon. My Dr told me its because the salmon probably was from an Ocean same as most crab & lobster. But if it is fresh water salmon I don't get sick.
My allergy is severe vomiting, nausea, & diareah, all severe and will last a few days. My hands will also swell.
I have never used an epi pen. I just wait it out because I haven't had the breathing problems.
I think I will be getting me an epi pen just to be safe.
9/30/10 1:02pm
Same here. I remember eating crabs as a kid and then one day after dinner I got severe hives and was brought to the doctors. I'm 25 now, and I get really bad stomach ache and break into cold sweat if I accidentally ingest crabs.
I get similar reactions to lobster and crawfish too but I'm usually ok with shrimp, especially shrimp that has already been shelled. I could eat plates of fresh boiled shrimp and I'd be fine. I can also eat scallops and pretty much all the other seafood I've tried.
However, I just got my allergy test results back (I went to see the allergist for my cat allergy) and I'm actually more allergic to shrimp than I am to lobster and crab. The doctor told me to avoid all shellfish including scallops though, but honestly I don't know why I have to stay away from scallops if the test result shows I'm not allergic to it.

Hi Crab Wary,
I am a board certified allergist in the Chicago area.
You apparently have shellfish allergy. This does not mean you have allergy to other fish (non-shellfish). You certainly may, but until you have a reaction, it is assumed that you are free to eat other fish. I have many patients with shellfish allergy who consume all kinds of other fish.
The key is to be on the look out for cross contamination with shellfish, if shellfish is served from a restaurant or store where you are eating or shopping.
You must have an Epi-Pen or Twinject for self injection of epinephrine in case of accidental exposure. This must be prescribed, along with proper orientation on how and when to use it (as well as possible side-effects).
Even if you avoid all fish, you should still have access to epinephrine especially when eating out. Shrimp may have been grilled (without thorough cleaning of the grill) just before grilling your vegetables or soy burger (for example). Many severe reactions occur by accidental exposure.
You should see an allergist, if you have not already. There is plenty of more information for you.
Check out my site: www.allergy-asthmacorner.com
Shellfish allergy will be a future entry on this site (above).
Good luck

...as I just found out the hard way, my "shellfish" allergy (e.g. lobster, shrimp, clams) also pertains to CONTACT with FRESHWATER invertebrates (i.e. "shellfish").
If you're like me, those of you out there with shellfish allergies may also need to avoid FRESHWATER shellfish. I was standing in a river/on a riverbed here in Colorado over the weekend. My feet developed a pretty nasty urticarial reaction (i.e. hives).
Surprise, surprise...it turns out that the rivers and lakes here and elsewhere contain plenty of freshwater shellfish; these would seem to be pretty closely related, then, with their saltwater relatives - evoking similar allergic responses in some of us. Just FYI...
Keep that Benadryl and EpiPen handy!

HI, I saw your post. Last night, while eating crab legs, which normally I have had no problem with, I suddenly began feeling tingling on my lips and tongue. I discontinued eating it and still felt weird when I got home and went to bed. My lips and tongue still feel a little funny today. I called my doctor and he'll see me for a skin test. Are these symptoms that anyone else experienced? Is it related to the crab?
My daughter is 6 and last summer complained that she couldn't breath/swallow after eating fish sticks (cod) and albacore tuna. Said it felt like a bubble in her throat. I recognized the symptoms as a possible allergic reaction and gave her liquid benadryl. I made a call to her pediatrician and ordered her to carry an Epipen. She has never been "tested" and I don't know if she, too, would be allergic to shellfish or not, but would like to find out. Will she be able to tolerate the skin test. I don't know if I want to put her through it. I can tolerate it, but she's only 6.

Hello my daughter woke up to swollen face from eatting shimp, i know she has allergies but not to shimp, i guess now she dose
12/13/07 7:13am
Yes, by all means you - and your daughter - should get tested. Why play a game with your lives? There are alternatives to how the tests are done. Some are skin tests, while others are blood sample tests. You should talk to your allergist about it.
Regarding your crab experience - there is a nasty trick in the food industry to replace crab meat with immitation meat made from Alaska Walleye Pollock fish. So... you may even be fine with crab, but might be developing a fish allergy.
As I have a potentially fatal allergy to fish - although not to shellfish - I have done plenty of research on the subjects. My allergist, however, told me the fact is that a fish allergy - once gotten - will never go away, and most likely will get worse. Also, to note, sometimes it may not appear right away. You could possibly even eat whatever you are allergic to a couple of times with no reaction. Then, the next time, you could drop dead (potentially). I've even heard of a nurse having an anaphylactic shock while on duty at the hospital. She swelled up so bad that they could not save her - even after having her prepped within minutes.
So the moral is - don't play around. Get tested and find out all the facts from your doctor. And that goes especially for your daughter. Good luck!

I don't think a six year old would have any trouble with the allergy tests.
When I had it done, I was nervous (thinking it might hurt), but it didn't at all. Maybe there are different kinds of tests, but with mine they barely scratched the skin on my back with a plastic device. It was far less painful than having blood drawn or getting a shot. I could barely feel anything at all until the areas where I'd been scratched with things I'm allergic started itching--it felt roughly like mosquito bites and went away within a half hour or so.
My point is that NOBODY should be afraid of getting tested. It's not painful at all.
7/29/08 10:14pm
I too am allergic to shellfish. Although they say it is not genetic, my father was allergic and his mother was also. I have different reactions, depending on the fids and the concentration...I guess. I recently went to an allergist and refused to be pinched over 50 times and be injected with something I already knew I was allergic too. I asked the doctor to do a blood test instead. It's quick and not too uncomfortable. My 5 year old aslo had it done.
3/19/09 8:43pm
You should do some research on blood testing for allergies. It is not conclusive. My daughter had a blood test which showed positive for walnuts and pecans, a few weeks later a skin test also showed pistachio and hazlenut allergy. If done by a good allergist, the skin test is one or two panels that pricks your back for all of 2 seconds. My 5 year old said ouch and that is pretty much it. It's really not a big deal and worth saving you or your child a life threatening reaction.
5/17/07 12:31pm
Hi, I was wondering if anyone eles had a sever allergic reaction to shellfish and having a hard time going out to eat? I'm 38 and just found out that I no longer can eat shellfish. I started to have ichy hands and body then hives all over then started to swell up. First my faces neck and then haveing a hard time breathing. They told me I can't eat out of the same oil,pan or grill. I have to watch what are in things to make sure they don't have shellfish or any kinds of it. I can't eat chinesse food. It has been a big chore and pain on me and my husband. We live down south by the water so it doesn't give me much of a choice. If any one eles has this please let me know what I can do or what you do. Sincerely,

Hi;
I don't know if I can be of much help but I have a shellfish allergy too and it's very severe. I didn't know I had it until two years ago and I've almost died twice. The first time I passed out in a gift shop (3 times) I couldn't get up off the floor. They thought I was having a heart attack and rushed me to the hospital. They didn't figure out the problem. The second time I was on a cruise and passed out. The infirmiry worked on me most of the night and said they thought they lost me 3 times. Just be very careful because many things at resturaunts are contaminated by shellfish cooking on the same grill. Good Luck. Hope You do well.
8/17/07 10:03am
Hi Bumbed out,
I too have a shellfish allergy and it is extemely difficult to eat out! I nearly died eating a chicken sub at a famous sub shop. Now I've got strict instructions to only eat where there is no shellfish, which is hard cause living close to the water in the summer months everything is Seafood realted. I suffer from anxitey as a result of this allergy. If you look long and hard you can find a few places that may accomidate you. I can eat at a half a dozen places but I still feel like it holds me back from living a normal life. I hope you can find a balance that works for you I still struggle but my family is really supportive. I'm 29 now and have had my allergy since I was 5.. but have been forbbiden to eat out since 18.
best of luck.
8/21/07 4:43pm
Unfortunately my son who is 6 is allergic to shellfish. I feel so bad because I feel like I can no longer eat out with him because I worry every time his chicken fingers were cooked in the same deep fryer. Are their any chain restaurants that you felt really are sympathetic with this allergy? Also, are you allergic to nuts and peanuts because he is also. Hopefully he can lead a life without feeling deprived of everything. Sorry to hear of your troubles but hopefully someday their will be a cure. Concerned Mom

Hello:
My name is Dawn and I have been diagonoised with a shellfish allergy. I have eatten shellfish all my life. Then one night I was eatting shrimp at home and turned beat red, like I had been scalded. My lips and tongue began to thingle and they told me to carry an Epi-pen and stay away from seafood. Then a few months latter I ate tunafish and made chowder for my husband and son, but did not eat any. Within minutes I couldn't breath, so I know what you went through. I have been tested by two allergist and both get negitive readings, so I don't get it, but they say it will kill me if I eat it again. I don't go out to eat either. I have lost weight do to begining afraid to eat and what will trigger it next time. If you have any advice please pass it on. Fish is in so many things that we don't even know about.

Hi, im 20 years old and about 2 or 3 three years ago i found out that i cant eat shellfish either. It first started with shrimp and i got rushed to the emergency room and stayed there for a couple of hours months later i forgot all about it and then came across some crawfish over my girlfriends house i at about 2 1/2 pounds of it and i'll say about 10 or 15 minutes later i started to get hot or you can say heat flashes throughout my whole entire body then my eyes started to turn red and i started to itch and my skin started to turn red and i broke out in hives all over and i barley could breathe. So i wonder what is the cause of this i have all sorts of seafoods when i was little and stayed in Miami, Fl. so what is the cause of it.
11/ 6/07 2:54pm
Not to add to your worries, but you should also be wary of porous bowls, such as clay or unglazed ceramics. I've gotten sick after eating cantalope from an unglazed ceramic bowl that was previously used to serve a food that I'm allergic to (garlic). I thought the cantalope tasted a little funny, but had no idea that it had absorbed the garlic residue from the bowl. I was very sick.

I had my first sever reaction to shellfish when I was 21. Like you I had eaten shellfish for years and never had a problem. I went to the Keys for Father's Day. I ate tons of shellfish. On the way back home, my hands started itching. I couldn't figure out what was going on. Later that night, I woke up and couldn't breathe. My face was swollen to about 4 times the normal size. I couldn't bend my fingers and I felt like I was on fire. I went to the hospital and they gave me Benadryl. Which took care of most of it. Since then I stay away from most shellfish. I can eat oysters and clams. I am 36 now.
Here's what I do when I eat out.
If I am going to a seafood restaurant I ask to speak to the manager. I then explain the situation to them. I request that my food be cooked in a clean fresh pan. I try to get food that is broiled instead of fried, baked or grilled. I've found that asking to speak with a manager is the best way to make sure that it gets prepared correctly. I also tell them what will happen should the slightest bit of shellfish make contact with my food. I have never had a bad experience.
Although, sometimes shellfish turns up in the wierdest foods. I went to a Chinese restaurant the other night and ordered won-ton soup. Have never had shellfish in it before. I am so glad I stirred it before I ate it. Because sitting right in the middle of the soup was a huge piece of shrimp. It ruined the whole meal, because I had to wonder what else might be hiding in the other food. I then proceeded to explain to the waitress that no seafood could come anywhere near my food.
Finally, the best thing to do is when in doubt explain it to the server or the manager. Most are very willing to help and accomodate your needs.
2/ 6/08 2:15pm
I am in the same boat you are. My daughter is only 2 and we went to Red Lobster. She had chicken and fries and started getting hives everyone and her face was swollen. She has always eaten fish but I am guessing that they cooked her chicken in the same grease or oil as the shellfish. I don't know where it is really safe to take her.
2/20/08 6:27pm
Hey All,
I have been allergic to shellfish since I was 8 years old. The one piece of advice I can give you is when you are going out to eat pay attention to your body. I can honestly say your body will give you signs. When you first eat something, especially fried foods, pay attention to your tongue. It will give it away everytime. The tingling usually begins within a few seconds to a minute if there has been exposure to an allergen, or it has been cross-contaminated. I can tell and I will not eat it. Hopefully, it's the same with most of you. I have asthma, also, so it can be very ugly. I have had it happen on many occasions since then, but growing up with it and having very insensitive family members..
I learned how to keep myself from having too bad of a reaction. When you're eating out just pay attention to your tongue and your body. The more you eat or the longer you stay in that seafood restaurant trying to tough it out..the worst it gets!! Good luck, All!!

I had a near death experience myself with a blue crab party last year. I have been attending this party for years so you can imagine my surprise. I was tested and found that I am also allergic to shrimp.
I can eat oysters and clams though and have since been searching for an explanation.
Why some shellfish but not others?
Have you been told why this is?
8/21/08 2:18am
You will most likely be allergic to one species branchgroup and not the other.
Crustaceans are shrimp, crab, lobsters, this is one group.
Oysters, clams and other filter feeders are Mollusks, another species group.
Scaled fish is another group.
Cephalopods is another, octopus, squid, cuttlefish is another group.
But be wary, octopus eat crab, and will most likely cause a reaction to people allergic to crustaceans.
Also, cross contaimnation in restaurants is hard to avoid without speaking out to the restaurant.
Etc...etc..

I too am allergic to shellfish. I once got a reaction by eating eggs that were served with the same spoon used to serve shrimp. I am very careful when I eat out. I always ask the server and sometimes ask to speak to the chef to make sure that they keep shellfish separate from other foods, that they don't use same oil, same grill, utensils, etc. Two restaurants I've found are very good about that are:Romanos Macaroni grill, Bahama Breezes. You have to be proactive. Take the initiative and ask questions and make sure that the restaurant is a safe place for you to eat. Be on the look out for things that contain oyster sauce -- chicken lettuce wraps for example. Sauces in general could contain many different ingredients not listed on the menu. Alwya ask. When in doubt...don't eat it.

Shellfish in terms of "food" are technically two animal categories people roll into one, crustaceans and mollusks.
Clams and Oysters, and Abalone are Mollusks.
Lobster, shrimp, crab, and are in a different group called crustaceans when it comes to allergies.
Being allergic to crustaceans does not make you allergic to mollusks, but if you eat a giant clam that has made lobster and crab it's primary food source, you will most certainly get the allergic reactions.

I became allergic when I was in high school after eating shrimp before a school homecoming dance, and I had eaten shellfish plenty before, but had my appendix taken out a month earlier, which I feel could have impacted it somehow. Within about 2 hrs I had swollen fingers, feet, lips, and my tongue was starting to swell and hinder my breathing. I went to the ER for the remainder of the evening.
Now I'm 21 and still have pretty bad anxiety about what happened, ESPECIALLY when I go out to eat. I get really nervous because you never know if they truly are taking the right precautions with your food, so by the end of dinner I'm always really anxious and get the tingles all over just remembering what could happen. So then I get even more anxious wondering if it's just in my head or if it's really happening. So I definitely understand where you're coming from. And, I live in Maine, which is known for its shellfish, so it's extremely difficult finding a safe place to eat.
Cooking at home has become more common to me, and healthier too. Plus, it's made my boyfriend I much closer to be able to do things like cooking together, which has helped me to think more positively about my allergy, since it is very frustrating!

Shrimp and salmon steaks are two of my favorite dishes, I'd take them over beef--but at 56 I cannot eat them any more. 25 years ago if I was on the coast and indulging every night, after a week of salmon diet I would have a scratchy throat--now it burns and swells after eating 10 shrimp. suggest that if you have issues with seafood allergies, watch out for the progression of the allergy: it really ramped up for me this last year.

I too had a surprise reaction to crab starting in my late 40's after I had enjoyed a lifetime of eating it. My reaction was full anaphylaxis. Luckily, my husband, a physician had instant access to epinephrine in his medical bag. The incident repeated itself a few months later, this time I had an epi-pen. My allergy list is a little strange, being that only crab, lobster, and crawfish bother me, no problems with shrimp at all. I have been told that sometimes allergen changes occur with menopause. Could be. Easiest way to handle it is to let restaurants know, let people you dine wiht know, be educated on ingrediants, inform your hostess at parties, and never ever be without an epi-pen. BTW, if you participate in ocean swimming activities (like snorkeling), you should tape your epi-pen in the waterproof case to your thigh in the event you should come in contact with crab or other known allergan. With the pen always with me, I take the allergy in stride and know some have lots worse to deal with.

Hi I'm so very allergic to any seafood to the point that I cannot go into any resteraunt or store that has seafood. if I smell it or touch someone that has eaten or touched it. it started when I reached my 30rdies if anyone has more info please let me know

We found out my son was allergic to shellfish, mollusks and fish when he was 18 mos. old. He is so severely allergic that if you eat any of them and touch him without scrubbing with soap and hot water he will break out in blisters. Being in the same building where they are being openly cooked (open grills and hibachi) and places that cook large amounts of seafood (asian restraunts, seafood joints) is enough to set off an anaphlactic reaction. The best advice I can give is know where you are going out to eat. Check out the restraunts website. Alot of chains have a website that lists the foods safe from the 8 major food allergies. If they don't seem to have alot of shellfish safe foods, don't eat there. Also, when you go out to eat, as soon as you walk in, ask to speak to the manager. Tell them about your allergy. If they give you the blank stare...get up and leave. The restraunt manager should be able to tell you what is safe for you to eat and what accomadations they can make to help you. We tend to go out to eat at the same select few places simply because the managers were the most knowledgable and willing to work with us. One local place was even willing to make my son (who's almost 11 now) a steak by putting clean tin foil over the grill and use clean fresh utensils and not cook anything with seafood anywhere else on the grill while they were cooking for him. This was a rare treat for him and we left a HUGE tip for both the server and the cook. Calling ahead to let the restraunt know you'll be coming in and your food allergies also helps alot.
My best advice overall is to communicate with the restraunt...that means with the manager, server, and even if necessary, the cook, and tip well when they go out of their way to accomadate your needs!

Recently I have been diagnosed with an allergy towards shrimp and crab, thus, an allergy that follows under the shellfish category. My specialty doctor performed a skin test that confirmed my allergy.
Before these tests, I experienced an allergic reaction while working out on an elliptical machine. About 20 minutes into my workout, I started feeling itchy throughout my body and somewhat in my throat. I rushed to the shower, and no sooner, I was breaking out in hives. I was breathing fine and didn't feel my throat closing, however, the excitement of everything got me nauseous and faint-like.
For that brief period, I did find it hard to breath. I took some benadryl, and before I knew it, the hives had gone away. I was feeling much better, although, most of my body was bright red (sunburn-like) and I was extremely itchy all over my body. Miraculously, this was the worst of it. Everything seemed to subside completely several hours later.
I called a nurse that evening and she said she thought it was related to the shrimp I had eaten an hour before my ordeal. Funny, I said, I had the same shrimp the night before!? Nonetheless, as I now know, these systems can develop anytime if you're allergic to shellfish.
Well, at the time I didn't stop eating shrimp. As a matter of fact, from that point, three months prior, until now, I consumed a lot of shrimp without any side effects. Yeah, I loved the stuff!! However, a week ago I was playing basketball when I noticed my hands getting quite itchy. This continued for awhile until I felt the itching spread. Then, I thought, I had eaten shrimp an hour earlier. Eureka! My symptoms this time were minimal compared to my first outbreak as I only suffered some itching and a few hives here and there. Nonetheless, I immediately made an appointment with an allergist.
One must take food allergies seriously. Others may have life threatening encounters. I should've gone to the doctors with my initial experience.
I'm curious if anyone else has had similar reactions while working out, but not from simply ingesting the food...?
7/17/07 11:50am
Hi all. I almost went to the emergency room yesterday for a severe allergic reaction that escalated from the day before. The EMTs who examined me decided that I would be fine just going to my doctor, fortunately. What I ate the day before yesterday was a salad with shrimp and peanuts, and while the hives started appearing on my neck and chin a couple hours later, the swelling in my neck, lips, face, and tongue got progressively worse overnight and into yesterday morning. This is the first time in my life that I have had such a reaction to anything that I have eaten, and I will not know exactly what caused it until I get an allergy test in a couple of weeks. But what's worse is that I also believe I have a wheat allergy (which seems to cause gastrointestinal problems)! Aaaargh.
Anyway, the reason that I am responding to this specific post is that I did go for a run the night I had hives. In my ignorance, I thought the hives would just go away on their own. It was an unpleasant suprise to wake up at 4:30 AM because my neck was itching so badly! In the end, though, I also do not know if running is connected at all to my symptoms, i.e., by exacerbating them.
8/28/07 4:42pm
I had a similar experience. After eating shrimp and crab hours earlier, broke out in hives after walking around on an exceeding hot day. Found an interesting website on which the author theorizes that certain factors such and excersize, heat, etc. can cause another allergic reaction to kick in by stimulating the autoimmune system.
9/ 7/07 3:56am
I wasn't working out, but just was about to get up from the table at a seafood place, had just ate alot of shrimp and crab and experienced almost all (if not all) the symptoms you just described, just didn't have hives..which now been told by my allergist to stay away from all shellfish that next time it could kill me. Which is a shock after years of enjoying shellfish and never had a problem til last month!
11/24/07 12:31am
i just found this post because i had a similar thing happen to me twice. the fisrt time i thought it was just a fluke, but it happened again tonight, so i guess it must be related. but both nights i ate shrimp and then went to the gym for a pretty hard run the treadmill. after my run my face itched and i looked in the mirror and saw hives developing. i have eaten shrimp tons of time, and had no problem, its only when i work out right after. i just take some benedryl and it goes away.
11/28/07 12:57pm
It's good to hear someone other than myself has this strange reaction after exercising.
The allergist first advised me to not exercise after eating shrimp. Well, that makes sense.
But after the skin tests, the Doctor said I was allergic to shellfish and that I shouldn't consume anymore.
Can my allergic reaction worsen. I wouldn't want any life threatening reaction from ingesting shellfish. So far, it's only been hives outside my body and they go away quickly with Benadryl.
12/17/07 4:30am
well, hello!
I didn't know that I was allergic to prawns until yesterday. I had a couple of prawns about an hour before working out in the gym and broke out in hives an hour into the workout. My face developed a couple of nasty hives which looked like big ugly pimples and felt like horrible mosquito bites. However my body wasn't really itching, just a slight itch here and there.
I immediately stopped working out. My friend gave me an anti-histamine pill. The hives went away shortly after I took it and I took a cold bath as well to bring down the itch. So I guess exercise do induce allergic reactions because I am a fan of all kinds of seafood and have been eating tonnes of them my whole life without getting any kinds of allergic reactions. I shall just be more careful not to eat any kinds of seafood before working out.
:)
12/20/07 9:16am
Hello! ***UPDATE***
Well, last week I had shrimp cocktail and approximately 2 hours later, I broke out in hives....NO exercise this time. The hives were mostly facial - some on my chest and back. They didn't itch too badly. I took some benadryl and they subsided shortly after.
I guess it's official. Very strange, because in between my previous two bouts I was fine if I didn't exercise after consuming shrimp. This time, however, I didn't do much activity at all.
Are hives the extent of it for some, or can one eventually have life threatening systems?
6/ 8/08 7:10pm
Regarding exercise-induced food allergies, I had trouble with off-and-on, unpredictable allergic reactions (anaphylaxis) for years, then finally I found a doc that could figure it out. After being investigated for tons of freaky autoimmune stuff, he finally decided that my "idiopathic anaphylaxis" was being caused by a combination of food allergies and exercise-induced allergic reactions. His advice: do not eat for four hours prior to exercising, and before exercising, take one 25mg benadryl and two over-the-counter Pepcid ACs (the benadryl is a histamine blocker and the pepcid AC, as weird as it sounds, blocks some other component of the immune system that can also cause severe allergic reactions - maybe it was mast cells, or something like that, but I can't remember). Anyway, after nearly 10 years of having random severe reactions, I have now gone nearly THREE YEARS without symptoms. Give it a try - couldn't hurt.
7/ 3/09 1:43pm
I was dancing when my allergy flared up two hours after I ate shrimp-- my doctor told me that physical activity will increase your reaction immensely, so keep that in mind!
As far as if the reactions will get worse? It's a possibility. Some reactions do get worse over time with the next occurance, so be careful!

I don't know why none of the hundreds of people seeing this thread has mentioned this, but:
it is a well-documented fact that Histamine release and the resulting allergic symptoms CAN RESULT FROM SUDDEN PHYSICAL EXERTION, EVEN IN THE COMPLETE ABSENCE OF ANY ALLERGENS.
And this can refer to physical exertion that the body, for wahtever reason, perceives to be "sudden exertion," even if you may not consider it to be. Could be that histamine release from both sources combined to cause your symptoms. I would suggest that maybe you can continue eating shrimp if you want to, but not within 12-24 hours of any vigorous exercise?

I was told that there is a toxin in scallops that I can not detoxify and this is why when I eat scallops, I become very sick to my stomach. The first time it happened, I didn't get sick until a few hours later, but the second time (I also ate a lobster tail) I had to stop eating and leave the restaurant. I don't believe this is classified as an allergy, but others may have the same problem.
12/19/07 4:41pm
Like you slinkyplinky, my reaction to shellfish is not swelling or itching, but more like a reaction one gets to food poisoning. Severe gastrointestional distress (cramping, vomiting, diarreha) It started in my early 20's. Before that, I could eat shellfish without any problem. I experienced reactions to scallops, clam chowder, crab dip and oysters before finally putting two and two together and realizing this reaction occured wheneever eating shellfish. So far, shrimp does not seem to bother me, but I eat very little of it and rarely. All other fish is fine for me. But I avoid shellfish like the plague.
1/17/08 10:29am
Wow I had the same thing happen to me! It started on my 18th birthday, I went out to a super fancy seafood restaurant and I got this medly of seafood stew and came home, a few hours later I was throwing up. From then on though, it only happens randomly when I eat crab legs. Its not everytime, but sometimes...I ate crab last night though and I had the WORST gastrointestinal distress I've EVER had in my life! Cramping, vomiting, diarreha, hot flashes, dizziness and I am still not 100% and it's the next day. Even since this started six years ago I've always wanted to eat Crab and now I don't think I ever want it again. This sux. Why is this happening?
5/28/09 6:07pm
My experience exactly -- at around 24 yrs old, I had a nice dinner of crab legs, which I often ordered back then. But I spent the night in the bathroom getting very sick from both ends. It took getting sick one or two more times after eating crab to realize that crab was the cause.
Other crustaceans are fine -- I eat lobster and shrimp. Other fish and mollusks are fine. I don't get itching or anaphylatic reactions, just severe gastrointestinal problems with crab.
9/16/10 3:46pm
omg the same thing happened to me that happens to you guys. it started when i was 19 and im 20 but i cant eat scallops or i get so sick, first at red lobster, i had to leave and couldnt finish my meal because i got so sick. i assumed i was just sick, and didnt think it was the food. but when i had scallops again a few months ago by the end of the meal i felt like i could die, and spent hours in the bathroom trying to keep myself from throwing up my guts, it was miserable!!
When I think about it i saw something on here about calamari making people sick, and i remembered ive only had it once but the same thing happened and i got really sick.
everyone is saying that if im allergic i wont be nauseous and everything like this and i'll just have a rash... but there is without a doubt something wrong because these things make me so sick! it took a while to put 2 and 2 together but i know its something with the scallops clams and calamari, maybe even more i dont know of yet
10/18/10 3:43pm
I have been allergic to crab for probably 10 years. The first reaction was just bad stomache and the second time hives everywhere, swollen lips, etc. Was told to stay away from crab. I still could eat shrimp. I ate mostly fried shrimp with no shell.
Well this weekend I had a stew with shrimp (shelled) in it. Within 4 hours of eating it I was extremely sick with vomiting and diarrhea the rest of the night. I now am wondering if this was an allergic reaction since the shrimp was cooked in the shell and all the other food was cooked with the shrimp. I did not have any other symptoms and no one else got sick.
11/21/10 5:27pm
Im 24. I went out for a nice dinner about a month and a half ago and i vomited two hours after eating dinner. i just had a feeling it was from the mussels in my pasta dish and since my boyfriend only had 1 and i had a plateful i assumed it was food poisoning. last night, at another nice dinner, we had the steamed mussles appetiser and sure enough about 2 hours later my body was violently rejecting the food, once again. this time, my bf are way more mussels than i did and he was fine. shell fish allergy? i love shell fish :(
my grandma had the same thing. late onset (early 20's) allergic reaction to shellfish. however, she tried them again in her sixties and to her extreme surprise, no reaction!
explain!!
7/28/07 2:15am
Well I discovered I had this allergy at the age of 3. I was playing like every other child on the sand at the bay, hooking prawns onto my fishing line and well the difference was that I had large swollen eyes and a very bad rash on my body. I was taken immediately to the hospital and they said that I was allergic to prawns. Further tests proved that I couldnt consume or touch any type of shellfish as well as squid, octopus etc. The only sea creature i could eat was fish! As a teen I wanted to try and gave it shot. I ate a prawn and well that put me into hospital with a deadly reaction. I couldn't breathe and felt like I was literally dying. I am now 29 years old and I've never touched it since. Ignoring my doctors advice about avoiding the shellfish today I decided to cook prawns for my husband and well suprise suprise, my hand started swelling up after I finished peeling the little buggers! I immediately stopped and as I type I am waiting for the reaction to disappear.

I'm allergic to shellfish but have had no troubles with handling it. While I was in college, I even worked as a waiter in a restaurant that served a lot of shellfish. Now, it's usually not polite for a waiter to handle a customer's food so I mostly kept away from it, but I'd often come into contact with it while cleaning up, sraping plates etc. I also breathed a lot of steam from cooking shellfish, which I do know can cause a reaction with some people (luckily this never happened to me).
8/ 8/07 7:34pm
Hi Crab wary,
I too have a shellfish allergy which I discovered two yrs ago. I ate seafood pasta that contained salmon and scallops. I had never eaten scallops before however I have eaten other types of shellfish (shrimp, crab, lobster, mussels) and seafood in abundance before the reaction. My allergist told me that I am allergic to ALL shellfish but am not allergic to salmon, tuna and other types of seafood. I remain sceptical about my alleged allergy to shrimp and crab but I have avoided ALL seafood since. Recently I had a reaction a few days ago when I was on the beach. I had eaten Chinese food about 30 mins before I went on the beach and had the reaction at the beach. I'm not sure if I reacted to the Chinese food (which may have contacted seafood) or the beach! Has anyone allergic to shellfish ever had an allergic reaction to the beach???
As for your question, you should be careful when eating any type of seafood as fish can contact shellfish in restaurants and packaged foods. To be on the safe side, always carry an epi-pen! If you decide to try a new type of fish, try a small amount and be very attentive to your body so you can quickly detect any reaction! Although I am allergic to shellfish, I have unknowingly eaten a salted type of fish and oyster sauce in the past and I have not had a reaction so I think reactions vary among individuals. Good luck!
8/14/07 1:55pm
Hey all! I too have a shellfish allergy. When I was young (8 or 9) I would get sick during the middle of the night for no apparent reason. After months of my mom keeping a food diary of EVERYTHING she cooked in our kitchen the DR was finally able to trace it back to shellfish. We had 7 children in our home so late at night when everyone else was asleep my mom would make a seafood treat for her and dad. It was on those nights that she boiled the lobster, crab or shrimp that I got sick. My room was right above the kitchen and just the steam from cooking it would set me off. The diagnosis was later confirmed with a ***** test and I will not even eat at a seafood restaurant for fear of getting a wiff of steam.
9/10/07 3:18pm
Since I have an allergy to shellfish and to salt water fish and to fresh water fish, I stay far away from any of them. My allergic reaction is severe so when I eat out, I check to make sure that my food is not cooked near any fish or shell fish. The cross contamination of cooking oil or surfaces can cause a severe reaction. I tried Glucosamin-Condrohtin (sp?) for arthritis, and within 20 minutes, I had a severe headache. I called the manufacturer, asked the ingredients, and sure enough, they used shrimp tails in the mixture. The assured me that they had removed all the iodine from the shrimp tails. I told them it's not the iodine, it's a protein that people are allergic to - unless of course, they do have an iodine allergy, which I do not... just try convincing others that it's not the iodine - even the nurse practioner at my doctor's office ---
So, the best way to make sure you don't have an allergic reaction is to not take a chance. It seems that fish/shellfish reactions are severe and I don't want to have the EMS at my side to eat something that is poison to my system!
9/10/07 8:53pm
I recently had a reaction to eating shrimp..giving me numb hands and feel, rapid beating heart, swollen tongue and shortness or breath about a month ago. I then made the mistake of going into a restraunt and ordering scallops (which I had always done in the past without a problem).. again I had a reaction this time more severe. Last evening while out with friends they must have started steaming some type of shellfish because within 5 minutes I was blue. I went and got an epi-pen but am completely FREAKED out by this allergy. Any suggestions on how to avoid being near the steam or not having a reaction like this? I am completely embarrassed by this and feel like I am afraid to eat anything out. Is this normal? Any suggestions on what to request at restraunts? Thank you
10/19/07 8:22pm
Hello everyone,
Will anyone let me know of any information they have on shellfish? Like what common protein(s) they share, and etc? I'm in the beginning stages of researching.
I'm currently a bio grad student at harvard and thinking about writing a thesis on this topic. (i'm allergic to shellfish too, btw) =D
Long term goal: to create a blocker or a "cure" so that people can enjoy eating lobsters along with the rest of the family for once!

This reply is to you Tony and also anyone else who is interested. Check out the website below. In the past this allergy elimination technique has saved my life and greatly improved my health. However, my chiropractor who used this technique in my town was killed in a car crash. Last week I developed an allergy that sent me to the ER. I suspect shellfish that was in the glucosamine product I took or possibly fish oil supplements. I'm still having some symptoms 4 days later and knowing my drug allergies it may be to the steroid I am taking to counteract the allergy. I turned as red as if I'd been lying in the sun all day and felt like I was on fire. That was the most severe allergic reaction I've ever had and was very scary. I am going to research NAET with a doctor that is in another town that is an hr. and a half away to see if it can eliminate something as severe as this. I know that it has eliminated my cottonwood allergy that kept me coughing constantly for months every year. I do have to re-do it about every 3 yrs. though so I'm not sure I'd trust it to still eat a food, but it would eliminate most of the danger I would think. The way it works is you hold whatever you are allergic to in a vial in your hand and get accupunctured. You do not eat or touch that substance for 25 hrs. Then you get retested the next visit and if you passed you are no longer allergic. It is an amazing thing. The problem w/ me now is figuring out what I am having such a reaction to as it is happening nightly to a lesser extent and I can't identify what is the common factor yet. However, the dr. does muscle testing which is not normal allergy scratch testing. These drs. can teach you how to also do this so you can test things yourself before you eat them to see if you are sensitive. There is also a man named David Hawkins who teaches this technique. He has audio programs w/ Nightingale-Conant. Keep me informed if you come up w/ anything else new at paulaantim@cableone.net. Here is the website below. I will also be checking it out in more detail as I've not had time to go there yet. I just started researching shell fish allergies to know what to avoid until I can get treatment.

In reading all these accounts I feel weird because my allergy seems to be more selective and crosses boundries. I'm interested in knowing what Maine Lobster, oysters, snails and squid ink have in common, because that is all I'm allergic to that I know of. I can eat Costco lobster tails (non-Maine lobster), clams, mussels, crab, shrimp, scallops, squid, octopus and everything else than the four named above.
The other day I went in for my first CT scan and when they injected me I started throwing up. Oh, by the way, my reaction appears to be gasto-intestinal, as it starts about 4 hours after I eat and then my body tries to get rid of it anyway it can, vomiting and diahrea for hours until it is out of my body, it is really bad, but not life threatening. I'm not so concerned about what happened with the CT scan although it may be relevent. Sea food and shell fish are my favorite foods, my first allergic reaction didn't happen until I was about 25 years old, 30 years ago; and I've found out about the others through trial and error over time. At least I can still eat everything else other than the four; I hope that CT scan didn't screw anything up and make be allergic to anything else. I haven't read about anyone else with a similar allergy.

Im allergic to shellfish, but not regular fish. How do i know if I'm also allergic to other seafood like octopus or calamari?
12/ 4/08 8:25am
I became allergic to shellfish and iodine just before my 21st birthday. My doctor told me that there are various fish combinations that can cause the reaction. She said people can be allergic to shellfish, line-fish, or calamari, all of these or any combination of these. She told me to stay away from shellfish but to try calamari and various linefish. I tried calamari and it didn't give me the full anaphalaxis but did make me feel sick, so I stay away from it. I can eat most linefish, but stay away from anything that eats shellfish eg. musselcracker.
As for the eating out issues discussed at length on this page, I have never had a problem in 17 years, I don't order fried fish at all in case it is cooked in the same oil as the shellfish. I have had no problem with grilled linefish as most restuarants have seperate grills for different foods, else I choose something completely different like chicken or meat. You just have to be careful and read the ingredient lists, also you need to read labels and be very careful of thai food as the curry pastes (red, green or yellow) all contain a shrimp / prawn extract.
I have also been told by my doctor that is is highly unlikely that anyone with food allergies that develop later in life that you can grow out of them, and you never know how long the desensitising by allergy practitioners will last. I don't think it is worth the risk.

Hi-you should make an appointment with your allergist. They can do either a skin or a blood test to determine what exactly you are allergic too. I knew that I was allergic to lobster but recently had a bad experience with shrimp. It was much worse this time and I went into anaphylactic shock this time including itchy hives head to toe. I even passed out, blood pressure was very low. MUCH worse than previous. I am 43 and up to a few years ago used to enjoy lobster and all shellfish. Only this past year did I have issue with crab or shrimp. Once allergic, always allergic and allergist says that it will get worse each time. So please have yourself tested.

In my case shellfish affect my eyes. My eyes get irritated, itchy, watery, etc. My swollen eyelids forces me to close my eyes. The weird part is that even the smell of shrimp can cause me a allergic reaction.
So believe me when I say that I stay away from all shellfish period.
I try not to enter seafood restaurants because the smell may seafood irritates my eyes. I am also cautious about ingredients in tablets. Their are alot of over the counter tablets such as vitamins and diet pills that contain shellfish ingredients.

Hi, I am 40 yrs old and recently have had mild reaction to shrimp but not all the time. My husband was convinced it had to do with the vein that runs along the spine and inner curve of the shrimp. I believed him because when he prepared the shrimp nothing would happen to me. Last night he made a soup with shrimp. I was fine for about two hours and then I carried my son to the car outside to go home and it was pretty cold.
While driving my scalp and ears started itching and I though "oh, Oh"
My face started burning and my ice watering. My husband had to take over driving. My tongue swelled and my chest hurt. I took two Loratadine allergy tablets that I had. When I got home I looked like I went through a couple of bouts with "Rocky" and lost. The hives went down because of the Loratadine but the swelling didn't. Even my fingers are swollen. I am still swollen and it's eight hours later. I am going to the doctor today. I hope this doesn't last a long time. But no more shrimp for me.
1/ 7/08 11:07pm
I absolutely love shellfish and eat it frequently, but I have found that when actually just touching the shellfish when eating it with hands (usually shrimp) it makes my hands itchy and a develop a rash with little bumps. Fortunately I have not experienced any breathing problems or facial swelling from eating the fish, but does the rash on my hands mean I may be at risk for a more severe shellfish allergy?

Hi guys,
I have recently moved to Australia from the UK. I have eaten calamari all my life, and loved it, also fish and prawns. However, I had grilled calamari about ten nights ago, and got very strange feeling - tingling and then numbness around my lips, gums and tongue. Then the numbness went to my hand, (this was all as I was riding my bike home after the restaurant). Then some of my muscles started feeling weak and fatigued, and at this point I got very worried and went to the emergency. A friend of mine, GP, gave me also advice over the phone to take some antihistamine, which I did. In the hospital they did some blood tests and neurological tests and they could not diagnose anything. I was on very lean and simple food until about a week later when I had some omlette, and the thing repeated itself. I have been taking antihistamines from the first bout, and am waiting for allergy testing that is being done now on a blood sample. It is quite worrying that the symptoms have not completely gone away and that eggs could start it off too. There was never any swelling involved, hives, redness, just numbness, and muscular fatigue. Has anyone had any experience like mine? And what did you do?

I guess I am a freak or something. I have a severe allergic reaction if I touch the shell or tail of shrimp, crab, or lobster(crustaceans), but I can eat them. If I touch the shells or touch something that someone who has touched shellfish shells I have severe hives and pain in my chest. I also have the same reaction to allergy medications like Zyrtech. I try to be careful, but I am a cook in central Florida so it is kind of hard to avoid. If anyone has any ideas how to fix this let me know.

I have a friend who is allergic to iodine, but has no problem eating iodized salt (which is in just about everything). Does anyone know why iodized salt would not cause an allergic reaction, while all other iodized products (iodine, shellfish, etc.) seem to?
4/29/08 4:51pm
Allergic reactions occur then Iodine is complexed (attached) to a protien, the way it is in some shellfish like oyster, clams, etc. Iodized salt is not comlexed. Also, cooking reduces the iodine content in food by 60%. That is why I can eat cooked lobster and shrimp, but not raw oyster and clams. However, iodine allergy and shellfish allergy are not the same thing. Some people are allergic to a protein in the shellfish and can't have it cooked either, and some are allergic to just the complex iodine in the shellfish and some are allergic to both.

Hey there, I think that I have developed an allergy to shellfish (or at least to crabs and similar invertebrates,) as I had crab legs two nights ago and woke up this morning with a spreading rash... I have been reading a lot of the posts here and some of them focus on a numbness of lips, tongue or throat, not a rash - In my research, I discovered that these symptoms could point to neurotoxin (poison,) not just an allergy - below info quoted from Allergy Capital dot com:
Toxic reactions to eating seafood
Not all reactions to seafood are allergic in origin. Ciguetera poisoning and paralytic shellfish poisoning are both caused by eating seafood that has been contaminated by algae-derived toxins. These toxins interfere with the function of nerve endings and are thus "neurotoxic". Symptoms occur within 2-3 hours of eating contaminated food.
Ciguetera poisoning
Ciguetera poisoning is triggered by eating tropical reef fish that have fed on toxic algae which produce a "neurotoxin". As larger reef fish feed on smaller ones, the toxin concentrates in the organs of larger fish such as red snapper, barracuda, sea bass, eels and kingfish. Because the toxin is heat-stable, it is unaffected by cooking. Symptom consist of tingling of the lips, tongue and throat, often followed by stomach upset, headache, fever and muscle aches and pains. Numbness, collapse, coma and confusion have also been described. Most people recover within a few days or weeks with supportive treatment, but ongoing disability has occasionally been described.
Paralytic shellfish poisoning
Symptoms of paralytic shellfish poisoning are similar to those of Ciguetera poisoning. Symptoms occur after eating shellfish that have fed on toxic algal blooms. A heat-stable "neurotoxin" known as saxitoxin is produced by toxic algae, which concentrates in filter-feeding shellfish. Because the toxin is heat-stable, it is unaffected by cooking. Toxin can persist in contaminated shellfish for several weeks (and sometimes months) after exposure to toxic algae.
Symptoms arise within a few hours of eating contaminated shellfish, and consist of tingling of the lips, tongue and throat, numbness, loss of balance, dizziness, rash, fever and sometimes muscle paralysis. Death may occur if the breathing muscles become paralysed. Recovery is usual if the patient survives the first 24 hours, although muscle weakness may persist for several weeks. There is no antidote to neutralise saxitoxins. Treatment is supportive, although activated charcoal has been used to bind and inhibit further absorption of toxin.

I am allergic to all types of shellfish.. I have an EPI-PEN and get a new script every year.. I enjoy eating Chinese Food. Chinese buffets can be a killer!! In fact I have he writtend in Mandrin on a card the has been laminated so when I enter an Asian resturant they understand right away.. I can eat fish!.. When I go to a supermarket an get fresh fish i insist that the person behind the counter washes his hands, changes gloves, cleans the scale, and if gives me ice to protect my purchase from the heat (I live in Texas) that he gets fresh ice from the ice machine.
When I go to a resturant I ask the server if it is safe to eat fish.. When they do not understand my question, I then inform them of my situation.. I have had the waitstaff from various places ask me a question like, "And your point being?".. I just get up and walk out! No shame i just wnt to live..
I even have to watch when I go out out on a date.. I tell the person that I am allergic to shellfish.. When they we go out to dinner and they still order shellfish.. I excuse myself.. Leave money for a Taxi and go home... I want to live..!

Shellfish and other seafood have been my favorite since a little girl. Last year on my vacation to Atlantis my boyfriend and I ate at a pretty nice rest.; I ordered lobster. I had a major reaction that night...throwing up and all. Probably the sickest I've ever felt in such a short period of time. But thought maybe food poisioning. Felt pretty bad the next day, but by the next I was fine. Then over holiday (either Thanksgiving or Christmas) I had some oysters and had the same thing happen; threw up, but not as severe. Obviously then I started to think something was up. My mom a few months later made crabcake sandwiches and I had a reaction to those, but again a little less severe than before. The weird part is I have eatten shrimp before, between, and after all these episodes and have had nothing happen. I'm wondering if there are different types of shellfish and if you could be allergic to one kind or the other?

On my 16th birthday I went to a japanese steak house and ate shrimp and lobster. I had never tried either. I thought it tasted gross! Within minutes, i couldn't breathe. I jumped up and tried to get someones attention. I was still able to drink somehow, so I gulped down water until the EMS arrived. They took me to the ER and gave me epinephrine. I was shook up for days. For up to a year afterwards I was having panic attacks. Still to this day, I will not eat anywhere that has shrimp or ANY other shellfish... It was traumatising. I am now 19 and deathly afraid of ANYTHING from the ocean, lol.

I was diagnosed with a shellfish allergy about 35 years ago. Since then, I have been extremely careful about what type of sealife that I eat. I have also discovered that you must be very careful when it pertains to over the counter medications, glucosamine chondroitin especially. While it does wonders for people with joint issues, one of the ingredients is a shellfish derivative. I was taking it for quite a while before I discovered that I had been handling a time bomb, literally. In any case, I have found some delicious shellfish substitutes at the supermarket, so they help to fill the void. My rule of thumb is: if it had tentacles or scales, it's safe. It's worked so far. (I'm keeping my fingers crossed as I'm typing. Good luck!

I developed an allerygy to shellfish...that is mollusk type shellfish. I can eat all the shrimp, lobster, and fish I can eat and feel no affects. One clam and I am a resident of the restroom or worse. Funny thing is I didn't react to clams until I was almost 25 years old.....eating clams almost weekly all my childhood. I am 52 now and still enjoy shrimp and lobster whenever I want but watch carefully when ordering anything associated with "shellfish". I sure do miss that bushel of clams and hot butter!!!!

Hey,
I acquired a pretty bad crab and shrimp (and clam and scallop) allergy around puberty, but I noticed recently that there's other food that I react similarly to, like heavy cream (in alfredo) and some cakes and boxed pasta mixes... I found the one thing they all had in common was Carrageenan, and when I looked it up it turned out to be a seaweed extract used as a thickener.
So if you notice any weird reactions, check that out...

I am new at this....my daughter who is four was born with reflux of the kidney so she has to get x-rays with contrast dye once a year. This year she had a moderate allergic reaction....hives on her behind and back of legs....eczema knees to head.....dry eyes.....sick to stomach and threw up once......itchy all over for about a week......not easy. We took her to a pediatric allergist and found out in addition to xray contrast/dyes she is also allergic to iodine, betadine and all shellfish.
The shellfish is what really scares me. She is only four years old. I am thinking not to give her any fish until I know more about cross contanimation, what is a shellfish and what isn't, what fish eat other fish, can fish get contaminated by shellfish from the water, production, store or eatery? I am thinking about getting her a JR EpiPen but plan to research it more pros and cons before I ask her allergist about it.
I read that the steam from shellfish could put a person in a shock.....
My husband got a dental injection a few years ago and he is sulfite sensitive....he went into shock twice within thirty hours....this makes it even more frightening to think of my little girl being accidentally hit with shellfish. With my husband we didn't know he had the allergy until after he was in ER....at least wtih my daughter we have warning.

i discovered that i was allergic to salmor first. the smell never agreed with me, but when i ate it for the first time my throat closed up so i had to spit it out. then i tried shrimp and the reaction wasnt sudden, but it was when i left the restaurant that i had difficulty breathing. so i am allergic to fish, except myoglobin rich fish like tuna. i dont get reactions to it. but white fish, salmon, and shellfish can be lethal.

For years I was able to eat shrimp without any problems. Its been 7 yrs now I can no longer tolerate it. My first reaction caught me by surprise. After eating a chinese dish that had shrimp it I broke out into huge hives on my face, neck, back ...all in my upper body. A co-worker took note of it and yelled out "My God...what has happened to your face?" Someone realized that it was a reaction to something and since I was already working in a hospital suggested I go to the emergency room. By the time I walked down there I had developed a cough and was wheezing. E.R. md said that it could be a shrimp allergy and only way to know was to be tested for it. I thought nothing more of it and sometime later had a shrimp and fish platter and same thing happened minus the wheezing. Just took soome benadryl and was ok. Then I knew to avoid it and started carrying an epi-pen. Well...after having dinner a a local chinese buffet and yes I avoided the shrimp and still developed a severe reaction. I asked the waitress to find out if everything was fried in the same oil as the fried shrimp. Yep...it was. I had eaten 2 small egg rolls, a fried bisquit, wontons and and chicken strip with lemon sauce. Now I ask if shrimp is fried seperately and shrimp fried rice has its own wok. Same should be done where ever shrimp is being served just to be on the safe side. Its been several days and am still still trying to recover from it.

My family and I ate out a few days ago. My son is 10 months old so he eats off of everybody's plates. My husband had ordered clam chowder, and shared with him. He really seemed to enjoy it but after about 5 teaspoonfuls he refused to eat anymore (which isn`t uncommon for him, lol) but was still hungry. After leaving we put him in his carseat for the 2 hour drive home. When we got home I noticed that his face, head and back were covered in a rash that continued to get worse for about 24 hours. The doctor identified it as an allergic reaction but at the time I had forgotten about the clam chowder so I didn`t know what had caused it. I believe that if it is the clams that he reacted to, it's probably just a shellfish allergy since he's tried salmon and battered fish which I believe is usually cod. After reading all of these posts I am sufficiantly freaked out! Should I give him him shellfish again to make sure that`s what caused the reaction or avoid it all together? Will the reaction be worse this time? Is he too young for allergy testing? Do I have to go to the doctor to buy and epi-pen or can I buy it over the counter? I have so many questions!!!!! Any advice would be greatly appreciated!
3/ 4/10 9:32pm
i have had reactions to lobster and calamari and that is it. I eat seafood all the time which includes many types of fish, shrimp, scallops, oysters, and clams and have been fine, it has just been lobster and calamari. Is there anything in common with these two items that would be the cause of the reaction?
9/30/10 1:10pm
I don't know about how old one need to be to get allergy test but it really doesn't seem like there would be a problem, I just got mine and they just took some blood samples and sent it off to a lab.
But I would say not to risk it and feed your son shellfish for now, until you speak to your doctor for allergy testing?
As for the Epi-Pen, I believe its by prescriton only in the United States. They have special lower dosage ones for children. You cannot buy them over the counter so you would need to see a doctor anyway, be sure to ask for an allergy test.

Yes,your point is great, if you are intresting in injection molding,please scan the next.
Reducing the cycle time on injection machines means not only greater part output, but also, in some cases, less total capital investment in tooling and manpower for a given job. One important way to achieve such savings is to optimize cycles by properly sizing a tool based on realistic shrinkage rates for the plastic mold material being run.

Within the last few years I have noticed that I am allergic to crab. But only crab. I am able to eat shrimp, lobster as well as all other shellfish but just the smell of crab makes my lips tingle and my throat constrict. I had never previously had crab or noticed this before but it seems as though it is getting progressively worse.
Any ideas?

I had been eating crab for a few years, with no reactions. Last april i ate some steamed crab legs and thought they tasted funny. but kept on thinking it was a different seasoning. 20 minutes later nausea set in, followed by vomiting, then extreme diarrhea. this lasted for an hour or 2 supposedly after i had nothing left to expell. it seemed like food poisoning symptoms. tried again 5 days later, same thing... same funny taste...both times they were purchased at the same store. wondering if i just got a bad batch of crablegs or if im allergic, havent tried any since then but i do like crab legs. anything else i can eat with no problem as far as sea food. any insight on this problem, i have no swelling or itching as stated with anyone else's problem. just symptoms similar to food poisoning or tainted food products..thank you for your time
9/30/10 1:05pm
If you've always been fine and only have gotten sick from this store's crab legs, maybe you can try another store? Or to be on the safe side, you can get tested for allergies you may have.
Although I have to tell you, this is the exact same reaction I get if I eat crabs/lobster/crawfish. I don't vomit but I would get really bad stomach ache and it's so bad that I feel like I would pass out, and I have shellfish allergy (just got tested)
12/12/10 1:34am
I know i am allergic to calamari the first time i had it i ended up in a Er getting a shot and sent home with some meds And same with the second time , Well for a long while i kept getting these small bug bite looking bumps that would itch like no tomorrow and then scab like a blister . Well i finally put 2 and 2 together i am allergic to shrimp it happens about a little after a hour after eating them i get a few very itchy small rashes and the pooes . Tonight i ate some shrimp and boom i got more than one patch this time and itchy . the reason it was linked cause just about 5 days before i had Shrimp and one popped up on my hand and my chin then tonight !!! it is crazy itchy seems worst than all the others and i only ate 12 shrimp . So guessing its just shrimp and calamari ? tuna don`t seem to affect me and i dont really like any other shell fish . And should i let the doctors know about this reaction due to shots or go to a allergist and get it on papers first ?

I had my first allergic reaction to seafood at the age of 30. Went to the ER and was told it was probably the shelfish I'd had about 1.5 hours earlier. With that I avoided shelfish, but a year later I was back at the ER after eating halibut. I went to an allery doc and got the shin tests and found that I was allergic to most seafood except shrip and tuna. Fast forward 15 years and yesterday I had a meal that included shrimp. Seven hours later I had an allergic reaction. I called the restaurant and asked if the dish included any stocks or bases that might include other types of seafood and was told it did not, but that it may have come in contact with other types of seafood during preparation or cooking...Reactions included hives, itchy/tingly eyes throat and ears and, unusually, very upset stomach. I took 2 Benedryl gelcaps, biting one open for fast reaction and kept my epipen handy. Can such a reaction occur 7 hours after consuming the seafood?

I am 73 years old and have fished for salmon, trout and salt water species for 50 years. I also eat my catch. 2 weeks ago I suffered extreme vomitting after eating a piece of purchased cooked salmon. I thought it was food poisoning pertaining to my paricular piece. My wife had no problems. Last night I ate salmon which I had barbecued again with the same result. Once again my wife was fine. I have made an appointment with my GP for some tests. But it is very scary.

Yes, your point is great; if you are interested in plastic injection molded please scan the next Low injection speeds are desirable from the standpoint of part appearance. If splay (visible flow lines generally radiating from the gate) is encountered, it can generally be minimized by reducing the injection speed. If the molding machine is equipped with programmed injection, an initial slow injection rate can be used until some material has entered the cavity; then a more rapid fill rate can be used without causing the splay effect.

Yes,your point is great, if you are intresting in injection molding,please scan the next. During injection molding, plastics may be subjected to an overload of heat. The result can be immediate decomposition and a very short lifetime. For a practical determination of their lifetime, plastic molded parts generally must go through a time period in actual service so reliable data can be obtained. However, the tests (usually per ASTM) used have a degree of reliability based on experience or as presented in an ASTM standard. If proper material and process controls are used, the parts might outlast predictions.

I had been eating shellfish alot in my younger years and loved it. However after I had my first baby my first meal of shellfish sent me to the hospital with a severe reation. I looked like the creature of the black lagoon. This was in 1968. Since then I have discovered that any type of shellfish that has legs that are salt water (not freshwater like crawdaddies) send me to the hospital. So, my favorite foods crabs, shrimps etc I havent eaten for several decades. I can eat imitation crab and can eat mussells, abalone, stuff like that but they do not have legs. So, I am 64 yrs old now. I stay away from those saltwater shellfish with legs. Yuck. But I dont want to go to the hospital..................... so that is why. I just dont eat it.

A common theme in many posts is "I'm allergic to this, how do I know what I can/cannot eat."
As far as I have researched, the major fish groups are not crossed linked for allergic reactions, (unless cross contamination from public eateries occurs).
What it means:
if you are allergic to scaled fish, you can probably eat othe types of seafood, but not ANY type of scaled fish, unless it is super frozen and super cooked, ie canned tuna maybe.
If you are allergic to crustaceans(shrimp, crab, lobster, etc.) your allergy is limited to those saxitoxin carring creatures, which happen to be infested with algae blooms.
If you are allergic to mollusks (clams, oysters, and filter feeders) you have a mollusk allergy applying to all filter feeders.
You of course should be tested by a doctor to be sure.
And in public, always be aware of cross contamination.
I found some useful information here:
http://www.allergycapital.com.au/Pages/seafood.html
I ate all seafood until my 18th birthday, and had tingling, inching, throat swelling, and rash folllowing a large lobster dinner. I am allergic to crustaceans, possibly due to my allergic reactions to algae bloom caused saxitoxin residue present in crustaceans.
But use your common sense, if I am allergic to crab but not octopus, the primary food source of octopus is crab, so octopi will most likely cause my reactions to flare, although the cephalopod species itself is not causing my allergies, octopus are highly likely to carry saxitoxins.
I eat crab claws once in a while, and take a claritin-D before I eat it to alleviate the body hot rash feeling. Crab is my favorite, and I noticed if it does not touch my lips, I don't get the annoying itching/swelling on my lips, so I drop it into my mouth, and take care not to lick my lips.
I don't eat shrimp, lobster, because the reactions are severely annoying from those foods, and I don't feel it's worth it for those, since they are not my favorites.
I can eat any fish I have tried in 40 years, no reaction, clams and oysters produce no reaction either, but I hate clams and oysters, so I don't eat them for that reason alone.
My mom is also allergic, and has never stopped eating crab, it's her favorite, her allergies started around 30 yrs old. She is 78 and gets no reaction any more from crab, except for minor itching on her body after it digests. SHe also gets rid of it with claritin.
I am not a doctor, nor do I recommend anybody eating large amounts of the fish you are allergic to in an effort to nullify the allergic reactions.
I would recommend anyone with questions to speak with an allergy specialist or doctor for testing, to gauge your level of reactions, and to see if there is the possibility for you to even eat it at all.

I just turned 69 yrs. old and have had no allergies all my life. The other night I had crab legs at my sister's house and became very ill and swollen. I noticed I felt full after eating only 1/2 of 1 crab leg and did not eat any more. I went home shortly after this and by the time I got home, my stomach was swollen and I was nausiated. I threw up violently and could feel my face swelling and become red and a burning sensation. The tip of my nose and a line on each side of my mouth was pale white. My eyes became swollen and burning. I had a headache. When I looked in the mirror while washing my face, I could not believe what I saw looking back at me. I did not have any respitory problems. It is now 3 days later and I still have some swelling despite taking a fluid pill every day. I did not go to the doctor since it is a weekend and I did not have breathing problems. Is this a true allergy to crab legs? I also did not have itching, but did have burning and continued red rash and broken blood vessles on my face. None of the other guests were affected.
Your best guess would be appreciated.

I am 34 years and I started feeling tingling in my ears after eating shrimp, lobster ....10 years ago. Lickily I did not eat it that often. 3 years ago I went for a cocktail party and had a crab cake and hell broke loose. I have diarrhea, vomiting, dizziness, itchy and swollen face, and luckily I managed ti get epi-pen within 15 minutes and everything subsided. 6 months ago, I went to the mosy popular sub-restaurant and orderd a beef sandwich with beef soup, before I could even finish the soup I had a swollen throat with pain on swallowing and did not have the rash and the other things. I went to the ER and got epi-pen, benadryl and a steroid. 3 months ago, I went to a different restaurant and ordered ribs and mushrooms. I confirmed with the waiter that the mushrooms did not have any "seafood." Before I could even finish the dish, my throat was at it again and I ended up in the ER. Later on, I figured that the mushrooms had oyster sauce. I had my blood tested and reacted strongly positive with all the types of shellfish and fish except walleye. Now I am so scared, I can't eat out anymore. Apparently, there is so much cross contamination out there. I have to read every label etc. I hope the scientists out there are going to come up with something.
yes, that is definitly a shellfish allergy, you might want to see if shrimp and scallops do it too... by just trying a little piece. I aquired my shellfish allery around puberty, and I also found out throuigh trial and error that I'm allergic to Carrageenan, with is a seaweed extract used to thicken thiings like heavy cream.
Year ago I worked in a restaurant for a summer job and every time I'd handle shrimp in the shell my hands would swell-up and itch...I figured this was from the spikey/sharp bits on the shell and hence wore gloves. Now I'm in my early 30's and recently (last year or so) every time I eat crab I get a "hot" feeling, my eyes feel funny/puffy, and my stomach burns, then bad "have to run to the toilet" an hour or so later - is this an allergy? Should I get tested? I don't get a rash or hives. The thing is, I don't always have a reaction to shrimp, but I always have one to crab. If I was truly allergic wouldn't it happen every single time with all crustaceans?
On a scale of 1 to 10, 10 being my most problematic..
Lobster = 10
Shrimp = 10
Crab = 8
Squid or Calimari = 6 (This could have been caused by frying in same with fried shrimp)
Oysters = 4
Caned Tuna = 4
Scallops = 2
Salmon = 1
All other fish = 0
I recomend all fried shrimp to have it's own dedicated vat.
what is a vat.
in anyways i think you should get rid of all the shrimps and lobster recipies because they're a problem to you.
try to think and replace recipies for the lobster and shrimps maybe you could have shark recipies or snail recipies or something like those but not anything that is related to shrimps and lobsters except for crabs.
or your problem could be how your shef works how set the food or how he cook the food.
bad things could happen if your not sure on how well cooked the foodis,especially the shrimp and lobster because those crustaceons tends to takes a long time to be simmered and delicous including well cooked.
make sure you take this advices and I'm sure they'll help.
I had the same feeling of fullness after eating snow crab yesterday. I thought I did not have an allergy to crab. Previously, I had enjoyed Crab Rangoon at Chinese buffets. Plus, I tasted a crab leg a few weeks ago. However, I remembered having uneasiness in my stomach after eating shrimp, so I hate the snow crab with some awareness that I could have a reaction. After about 30 minutes, I began to sneeze. I felt like I had suddenly come down with a cold. I felt chilled after I left the restaurant and went into a bookstore. Next, I quickly went home and began feeling nauseous. Then, my eyes were itching, and I was still sneezing. I took my regular antihistamine earlier than usual. I looked in the mirror. My face and scalp looked sunburn. I had hives. By then, approximately 3 hours had past. I began feeling anxious and light-headed. I didn't want to take any chances. I had eaten about 10-12 snow crab legs. I went to the ER. Fortunately, my reaction was not life-threatening. I was told it could be life-threatening next time. The nurse, who also has a shellfish allergy, stated that life-threatening reactions typically occur within a few minutes after eating. I was told that the Zyrtec I had taken was not necessarily beneficial. I was given about 5 pills, which included Benadryl and prednisone. In about 2 hours, my hives disappeared, and I was discharged. My prescriptions included prednisone--"in case the hives come back." I asked for a refill on my epipen. I had a reaction to a bee sting when I was a kid, so I thought it would be wise to carry one in the event I eat food that was cross contaminated with other shellfish. I was told to stay away from any shellfish, including cramp, shrimp and lobster. After completing research, I learned that there are many other types of seafood in which I should stay clear, such as clams. The funny thing is that I love to fish. I recently moved to Florida, so I took up saltwater fishing. I had used shrimp for bait. As I reflect, I remember my hands stingy a bit. I thought it was the saltwater entering tiny nicks on my hands. I am not a big fan of eating fish, but I wonder if I would have a reaction to fish that eat crab--which a lot of them do. I have never reacted to tuna fish or polluck (Mrs. Pauls). I am not willing to take the risk on the fish I catch. I am interested in knowing if fish, such as flounder or grouper, should be avoided.
Hi,in response to your question...unless you have an allergist run a test,it is a hit and miss...I've never had any test ran,but by hit and miss only...I've discovered that I'm very allergic to shrimp and crawfish...but I can eat pounds of crab and all other shellfish and seafood...with no problem at all! can anybody tell me,why it is only shrimp and crawfish?
Hello???
I would say to you - NEVER eat shellfish again. You were just lucky that time. Listen to your body, it's always right!!! Next time you'll be on the floor, not breathing and won't be able to get to a Hospital fast enough.
Take Care and stick to Chicken next time
NO MORE CRAB LEGS for you!!
I found out I couldn't eat shrimp when I was 20 after eating out with some friends. I got really sick and had to go to the ER with major stomach cramps. Years later, I ate lobster and while everyone kept saying it was wonderful, I couldn't get paste the horrible metallic taste of it. I then got sick again later. So I've avoided all shrimp, lobster, crab etc. However, I love fish, and I've eaten snails and oysters with no problem. I always tell the doctor just in case I need to have a test with dyes that I have a shellfish allergy, and he said it was smart to do. It doesn't bother me that I can't some of this stuff because like I said it has a wierd taste to it that makes me gag. Not sure why that is though. The rest of my family laps that stuff up.
I dont have an answer to your question, but I do have a similar situation.
I have grown up eating seafood and living on the coast, I ate it regularly. When I was about 10, I developed a slight allergy to shrimp, which would make my throat a little itchy and uncomfortable. I have NEVER had a problem with any other seafood, and I love crab, lobster, (all crustaceans like shrimp), and any other seafood like oysters, scallops, mussels, (all in the mollusk family). I would continue to eat shrimp, despite the itchy throat, because I loved it so much until...
I was on vacation with some friends, ate some shrimp, and then went on a run. I think the run caused my allergy to react faster and more severely. My whole body broke out in hives, swelled up, breathing was difficult, and benadryl didn't even begin to help. I ended up at the ER, where they told me that the more you are exposed to an allergy, the more severe the reaction can become. Since then, I don't eat wild shrimp. Farm raised, (which isn't as good in my opinion), doesn't bother me, but I avoid shrimp altogether for the most part. I continue to eat seafood, including other crustaceans like crab, lobster, and crawfish with no problem. Just another opinion and example of someone who can't eat shrimp, but has no problem with other seafood. Hope this helps :)
Yes, your point is great; if you are interested in plastic injection molded please scan the next The constantly turning screw augers the plastic through the heated barrel, where it is heated to a proper temperature profile and blended into a homogeneous melt. The rotation causes forward transport. It is the major contributor to heating the plastic once the initial barrel heat startup occurs. The melting action through the screw is as follows: We are special in Plastic Injection Molding and Injection Molded Parts Manufacturerand please send email to: info@vulcanmold.com our website is http://www.vulcanmold.com

Molds using cold-runner technology offer opportunities to improve profitability with hot runners. If a conversion to hot runners provided cycle savings of only 10% for a 40-machine plant, this would free up four machines, or it could increase the revenue from the plant by 10% without adding any new machines. The elimination of a cold runner, as previously mentioned, can also reduce energy consumption and mold maintenance, eliminate granulator and sprue picker, and improve part quality and the efficiency of cavities.

Two different forms of shrinkage must be considered when designing to meet tolerances: the initial shrinkage that occurs while a part is cooling, called the mold or die shrinkage, and that which occurs after as many as 24 hr, called the after-shrinkage or after-swell. Some plastics are more stable than others after aging, regardless of their initial shrinkage. In many cases, low shrinkage may indicate greater stability. Some plastics have zero shrinkage, with others exhibiting little or a high degree of shrinkage.

Yes,your point is great, if you are intresting in injection molding,please scan the next. With thermoplastics the mold is kept at a temperature below the solidification point of the plastic, causing the injected melt to “freeze,” thus forming the part. After cooling, the mold opens and the part is ejected. From 85 to 90% of all injection-molded plastics are thermoplastic.

Bosses and other projections from the nominal wall are commonly found in injection- molded plastic parts. These often serve as mounting or fastening points. Figure 8-70 shows some typical boss designs, along with common problems. As with rib design, avoiding overly thick wall sections is important, to minimize the chance of appearance or molding problems.

These sea food can be found in the ocean floor are actually nasty and gross also very dangerous to our health. They not suppose to be eaten. These creepy crawling things are crabs,lobster,shirmp,clams mussels etc.. consume decaying organic matter that sinks to the sea floor,including sewage. A common demonator of many of the animals..They routingly eat flesh that would sicken or kill human beings. When we eat such animals we partake of food chain that inludes things harmful to people. God forbid us to eat the unclean animals. God in his wisdom,created certain creatures whose sole purpose is to clean up after the others. Their entire calling may be to act exclusively as the sanitation workers of our ecology. God may simply be telling us that its better for us believers not to consume the meat of these trash collectors.? Now you wonder why we have these deseases?

Rubber pad forming, also called rubber molding or rubber stamping, is similar to matched-metal stamping except that one of the metal dies is replaced by a block of solid rubber. The processing material cannot flow to the extent that it can with matched-metal die stamping. However, more uniform pressure is exerted on the material charge.

Mold temperature is not critical to the production of acceptable parts from PETG. When fast cycles are desirable, a cold mold can be used. When cavity filling is a problem, a warmer mold can be used. Mold temperatures higher than 130°F (54°C) should be avoided because parts may end to stick in the cavities.

A tool that has received all the necessary attention and care from the designer and moldmaker should be handled with extreme care so that the expanded effort is fully protected. Any protruding parts should be protected against damage in transfer. The mold surfaces, especially cavities and cores, should be covered with a protective coating against surface corrosion. The coating should be easily removable before the molding operation starts.

i am 52 years old i have eaten shrimp and seafood for 40 years , all of a sudden after eating a large order of fried shrimp, i become very swollen in my face and neck, i had a severe anxiety attack could not breath and broke out in huge whelps that looked like over sized mosquito bites that covered my entire body. my body became intollerant of these shellfish after all these years.
