ciguatera poisoning

The ciguatera, a coral fish, in his ongoing battle to remain a coral reef fish, secretes ichthyosarco-toxin–ciguatoxin, which is produced by the reef dinoflagellate, Gambierdiscus toxicus, and concentrated, unchanged, up the food chain by herbivores and carnivores. Ciguatera poisoning 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 and, unlike scombroid poisoning, may cause clinical disease regardless of the form of preparation

Clinical findings Onset 6-12 hours after ingestion; nausea, vomiting, cramping, diarrhoea, paraesthesia, reversal of temperature sense, arthralgias, myalgias, cranial nerve palsies, pruritus with alcohol ingestion, chills, hypotension, bradycardia, respiratory paralysis or death, average duration 8 days 

Management IV mannitol usually reverses symptoms
