[Seafood allergy].
Products of the sea are important source of food. Increase in consumption, due to their nutritive value has also led to a great frequency of reactions, including those that are immunologically mediated. Although hypersensitivity reactions to sea products are often easy to identify and can be confirmed by specific in vitro and in vivo tests, some patients can only be diagnosed by double-blind provocation test against placebo (DBPCFC). An atypical or incomplete clinical history suggests, always, contamination with toxins and/or parasites such as Anisakis. Crossed reactivity between different sea products is frequent. However, there are clinical differences between allergy to molluscs, crustaceans and fishes. From precise evaluation of the reactions to sea produce, will result a reduced and reasoned suppression from this type of allergens at food levels.
