    Does Cooking With Bottled Oyster Sauce Cause Allergic Reaction?

    I'm allergic to shellfish and want to make some chinese beef dishes..If I use a store baught Oyster sauce, will i get an allergic reaction? What are some ingredients i need to look for?..I'm currently allergic to Shellfish

    Answer

    If you are sensitive to shellfish, then any contact with it... whether by eating it or by breathing in airborne fumes/dust from it... can potentially cause an allergic reaction that could be severe. So I would urge extreme caution in using the oyster sauce. Cooking while wearing a HEPA-filter equipped mask might help prevent a reaction.

    Talk with your allergist if you really want to be sure you're not doing anything that may be harmful.
