some people are alleged to nuts, shellfish milk, and a lot of different things. some food can kill someone because of something called Anaphylaxis. Anaphylaxis is an acute allergic reaction to an antigen (e.g. a bee sting) to which the body has become hypersensitive. I choose the shellfish allergy because my mom is alleged to shellfish. An Epipen sent the meds that help with Anaphylaxis shock
