ciguatera poisoning


Also found in: Dictionary, Thesaurus, Encyclopedia.
The ciguatera, a coral reef fish, secretes ichthyosarcotoxin—ciguatoxin—produced by the reef dinoflagellate, Gambierdiscus toxicus; it is concentrated and unchanged up the food chain by herbivores and carnivores. CP is the most common marine intoxication in the US; 400 species of fish are implicated—e.g., barracuda, grouper, red snapper, amberjack, surgeonfish, sea bass; unlike scombroid poisoning, it may cause morbidity regardless of the form of preparation
Treatment IV mannitol reverses symptoms
