Crab Allergy Crab allergy is included among the big eight food allergies that occur among the residents of the United States of America. Crabs have been classified as crustaceans along with lobsters, shrimps and crayfish. Being allergic to the entire range of crustaceans is a usual occurrence instead of developing allergic reactions to isolated sea food items.


Reasons for Crab Allergy


Cha f1 along with a muscle protein known as tropomyosin is generally responsible for trigerring off allergic reactions to crabs. The body starts secreting histamine and a specific antibody called IgE is created to fight the allergens present in the crab meat.


Individuals who are allergic to crabs are advised to avoid all kinds of crustaceans. However, a group of people with crab allergies have been seen to tolerate mollusks. Being allergic to cod fish and salmon is not related to the allergy in any way.
