Seafood allergies are caused when the immune system tends to overreact. The immune system mistakes any certain protein present in seafood as harmful. This can then lead to the production of antibodies in a severe reaction by the immune system. Thus, whenever a person is in contact with an allergen the immune system releases histamine which causes the symptoms of allergy.
