![]() While eating the food is the major trigger for allergic reactions, some sensitive individuals may react to the fumes when seafood is being cooked, and occasionally from touch, such as when cleaning and handling fish or even “injected”, such as penetration of the skin from fish hooks. Do not try tinned fish unless advised by your allergy specialist. Seafood allergens are usually very heat stable and cannot easily be destroyed through cooking, although occasional individuals seem to tolerate tinned fish (intensely heat treated), yet are unable to tolerate the same fish freshly cooked. Therefore it is not possible to reliably predict the likelihood of allergy to one or more seafood group or individual seafood species without specific testing. Unfortunately, it is sometimes difficult to predict whether a person will be allergic to one unique protein allergen present in one food only, or several similar cross reactive proteins present in multiple foods, simply based on whether foods have a similar appearance. Examples of cross reactivity include people allergic to similar proteins present in one fish that are also present in other fish, or those allergic to proteins present in prawn, crab and lobster. If the same protein is present in several foods, then that person may have allergic reactions to any food containing that protein. Cross reactivity can be difficult to predict without testingĬross reactivity means that a similar protein is present in a range of different foods. molluscs), this cannot be guaranteed without specific allergy testing. Similarly, people allergic to crustaceans may also be allergic to edible insects such as crickets (that may be used as cricket flour in baked goods). ![]() crustaceans) can usually tolerate those from another (e.g. While those allergic to seafood from one group (e.g. Similarly, allergy to one crustacean usually means that all must be avoided. That means that one can be allergic to fish only, shellfish only or members of both groups. People who are allergic to one fish are usually (but not always) allergic to most other fish. Invertebrates (without a backbone) Shellfish: crustaceans including prawns/shrimps, lobster, crab, crayfish, yabbies and molluscs including oysters, mussels, clams, octopus, squid, calamari, abalone, sea slugs.Įven though fish and shellfish live in the same place, the protein allergens present in one seafood group are generally considered to be very different to those in others.The major groups of seafood that can trigger allergic reactions are:įish including salmon, cod, mackerel, sardines, herring, anchovies, tuna, trout, haddock, John Dory, eels, rays. Children with a history of asthma may be more likely to have severe allergic reactions to seafood. Occasionally, breathing difficulties may occur from inhaling fumes when seafood is being cooked, and in seafood processing factories. This is known as anaphylaxis, a severe allergic reaction. The most dangerous symptoms are breathing difficulties or collapse, caused by a drop in blood pressure (shock), either of which can be life threatening. ![]() Many allergic reactions to seafood are mild and cause hives (urticaria), tingling of the throat and mouth, swelling (angioedema) and/or gut reactions (vomiting, diarrhoea). About 20% will grow out of their allergy with time. It is more common in teenage and adult life than very early childhood. Whilst figures vary from country to country, approximately 1% of the population is estimated have a seafood allergy. ![]() Some conditions caused by toxins or parasites in seafood can resemble allergic reactions to seafood. Seafood allergy occurs most commonly where seafood is an important part of the diet, such as in Asia and Scandinavia. ASCIA PCC Allergic Reactions seafood 2022 168.87 KB ![]()
