FISH ALLERGY
humans can be allergic to fish (BWC, personal experience) although not to other seafoods such as crustaceans and molluscs. Gadus morhua allergy has been studied the most and other species are believed to be similar although not all fish species may trigger a reaction. Gad c l, a parvalbumin, is the major cod allergen. Symptoms appear within minutes to a few hours of eating fish and include swelling of the lips, tongue or throat, hoarseness, cough, hives, rashes, runny nose and watering eyes, and asthma. Potentially fatal if the throat constricts. Symptoms may be limited to nausea, vomiting or cramping diarrhea
