Fish allergy is an immune hypersensitivity to proteins found in fish.Symptoms can be either rapid or gradual in onset. The latter can take hours to days to appear. The former may include anaphylaxis, a potentially life-threatening condition which requires treatment with epinephrine.
Shellfish allergy is among the most common food allergies."Shellfish" is a colloquial and fisheries term for aquatic invertebrates used as food, including various species of molluscs such as clams, mussels, oysters and scallops, crustaceans such as shrimp, lobsters and crabs, and cephalopods such as squid and octopus.
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]
People may be allergic to other types of seafood, such as fish. [31] Fish allergies were found to be more common in countries that have high fish consumption compared to those with lower consumption. [32] Other common food allergens include soy and wheat. [33] Those allergic to wheat may be sensitized to any protein in the wheat kernel. [34]
Ciguatera fish poisoning (CFP), also known as ciguatera, is a foodborne illness caused by eating reef fish contaminated with ciguatoxins. [ 4 ] [ 2 ] Such individual fish are said to be ciguatoxic . Symptoms may include diarrhea , vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness , and weakness.
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]
The frequency of allergic symptoms in connection with fish ingestion has led to the concept of gastroallergic anisakiasis, an acute IgE-mediated generalized reaction. [15] Occupational allergy, including asthma, conjunctivitis, and contact dermatitis, has been observed in fish processing workers.
A wide variety of foods can cause allergic reactions, but 90% of allergic responses to foods are caused by cow's milk, soy, eggs, wheat, peanuts, tree nuts, fish, and shellfish. [41] Other food allergies, affecting less than 1 person per 10,000 population, may be considered "rare". [ 42 ]
