Histamine is not destroyed by normal cooking temperatures, so even properly cooked fish can still result in poisoning. [9] Histamine is the main natural chemical responsible for true allergic reactions, so the symptoms produced are almost identical to a food allergy. [10] [11] Rarely, cheese may be involved. [3]

When immune cells encounter the allergenic protein, IgE antibodies are produced; this is similar to the immune system's reaction to foreign pathogens. The IgE antibodies identify the allergenic proteins as harmful and initiate the allergic reaction.
Fish allergies are a frequent cause of anaphylaxis, a potentially life-threatening allergic reaction that appears quickly, impairs a person’s breathing and can send them into shock.
Shellfish allergies are highly cross reactive, but its prevalence is much higher than that of fish allergy. Shellfish allergy is the leading cause of food allergy in U.S adults. [31] As of 2018 six allergens have been identified to prawn alone; along with crab, it is the major culprit of seafood anaphylaxis. [13]
