Ok this may be a little silly but I thought I would ask some fellow nurses here on AN.Say you are allergic to mushrooms? Is it possible to have an allergic reaction from just being in the presence of a "cooked mushroom." Even if you have not ingested any of it or even touched it, in any way shape or form. It's a long story that accompanies why I am asking,it's mildly humorous in itself. But I am no way shape or form saying that food allergies are not serious. Just that I personally have not heard or seen anyone who had an allergic reaction just from being in the presence of a food that they were allergic too. Has anyone ever witnessed this?
