Anisakis Blastocystis Cryptosporidium Fish Prevalence

Sponsor: University Hospital, Lille

Summary

Anisakidae frequently infect fish species that are commonly eaten by humans. Some of them are recognized as zoonotic agents, and have a high impact on human health. Infestation results from the ingestion of living larvae from contaminated fishes. It can be asymptomatic or symptomatic, resulting in acute gastric, acute intestinal or chronic forms. Allergic manifestations are frequently encountered in gastric forms, but isolated allergic symptoms can occur after ingestion of Anisakidae antigens in raw or cooked fish. Cutaneous contact or Anisakis allergen inhalation have also been reported to induce allergy/anaphylactic reactions or sensitization in the occupational setting in Spain, Italy, Sicilia or South Africa. But no data is available in France. In this context, the investigators propose to determine and compare the frequency and characteristics of fish allergy in fish workers (fishermen and fish-processing factory workers) and a control population of workers without occupational exposure to fish, in Boulogne-sur-Mer, which is an important fishing port in France, and the first European center for fish processing.
