Ciguatera - Definition

Ask a question


Ciguatera is a foodborne illness caused by the ingestion of fish contaminated by the Gambierdiscus toxicus, a microalgae. The Gambierdiscus toxicus colonize coral in warm seas (mainly the South Pacific and the Indian Ocean) where there are fish (barracuda, groupers, mullets, moray eels, etc.) susceptible to becoming carriers of the toxin. Ciguatera causes digestive troubles such as vomiting and diarrhea, neurological and cardiac disturbances, and dermatological reactions (itching, intense sweating, etc.) These symptoms appear several hours after the ingestion of the contaminated fish.
