What is shellfish allergy?

Food allergies are when a person develops allergy antibodies (IgE antibodies) to a protein in a food, and when exposed to this protein it causes an allergic reaction. Shellfish allergy is when you have an allergic reaction to crab, lobster, shrimp, oysters, scallops, clams, or other shellfish. This is different from a fish allergy.
