Has anyone had experience in developing a severe allergic reaction to opening fresh water oysters in vacuum sealed bags with colored pearls? I have severe allergies to peanuts and sesame. I am also allergic to soy. Last night I opened oysters with my kids at home as something fun to do and I would up in the hospital with a very severe allergic reaction. Have no idea what fluid they were in. Have read online they could be in formaldehyde. But no clue. Looking for any information if something similar has happened to anyone else. Thanks in advance.
