Several shrimp species are known to induce allergy diseases. However, the whole spectrum of allergens they contain is unknown and few of them have been completely characterized.

We emphasize the species Litopenaeus vannamei , the most consumed shrimp in Colombia. Well characterized shrimp allergens are named following an official classification; nevertheless, they are better known according to the biological function associated with them. Tropomiosin, the main and most studied allergen in different shrimp species, is involved in crossreactivity among shrimp and other arthropods like domestic mites. The other characterized allergens seem...
