E. coli enteritis is inflammation of the small intestine from Escherichia coli ( E. coli ) bacteria. It is the most common cause of travelers' diarrhea.

Traveler's diarrhea - E. coli; Food poisoning - E. coli; E. coli diarrhea; Hamburger disease

E. coli is a type of bacteria that normally lives in the intestines of humans and animals without causing any problems. However, certain types (or strains) of E. coli can cause food poisoning. One strain ( E. coli O157:H7) can cause a severe case of food poisoning.

Bacteria may get into your food in different ways:

• Meat or poultry may come into contact with intestinal bacteria when being processed
• Water that is used during growing or shipping may contain animal or human waste
• Improper food handling or preparation

Food poisoning often occurs from eating or drinking:

• Any food prepared by someone who did not wash their hands properly
• Any food prepared using unclean cooking utensils, cutting boards, or other tools
• Dairy products or food containing mayonnaise (such as coleslaw or potato salad) that have been out of the refrigerator too long
• Frozen or refrigerated foods that are not stored at the proper temperature or are not reheated properly
• Raw fish or oysters
• Raw fruits or vegetables that have not been washed well
• Raw vegetable or fruit juices and dairy products
• Undercooked meats or eggs
• Water from a well or stream, or city or town water that has not been treated

Although not common, E. coli can be spread from one person to another. This may happen when someone does not wash their hands after a bowel movement and then touches other objects or someone else's hands.
