  Ciguatera and the Fish that cause Ciguatera Poisoning
Ciguatera is reported to be the most common form of sea food poisoning in the world (1, 2, 4) with the estimated number of cases ranging from 50,000 (1, 2) to 1,000,000 (3, 9) annually.
Ciguatera may also have a slow insidious onset if there is a gradual accumulation of toxins due to the continuing consumption of fish which have a low level of toxicity (10, 30).
Ciguatera may be caused by some 400 different species of tropical reef fish around the world (1, 16,), and, in theory at least, the avoidance of these species will considerably lower the risk of falling victim to ciguatera.

 Ciguatera - fish poisoning, Ciguatoxin, seafood disease, sushi poisoning
Ciguatera fish poisoning is endemic wherever coral reef fishes are a food source.
The toxin first affects the coral-grazing fish and is then passed up and through the food chain to the piscivorous fish (i.e., snapper, grouper, amberjack, barracuda) and finally to man. The toxin is not affected by either cooking or freezing, and the affected fish, cooked or raw, is not tainted by bacteria in any way.
A typical scenario of Ciguatera fish poisoning would include a delicious family fish dinner at the evening meal, perhaps applauding the successful fisherperson and the culinary skills of the cook.

 Ciguatera Fish Poisoning
A case was defined as ciguatera fish poisoning if there was a combination of gastrointestinal symptoms (i.e., nausea, vomiting, diarrhea, or abdominal cramps) and neurologic symptoms (i.e., muscle pain, weakness, dizziness, numbness or itching of the mouth, hands, or feet) in a crew member after eating fish on October 12.
These fish are then eaten by large, predatory reef fish (e.g., barracuda, grouper, and amberjacks), which appear to be unharmed by the toxin; because the toxins are lipid-soluble, they accumulate through the food chain.
Neurotoxic shellfish poisoning is caused by a third type of dinoflagellate with another toxin that occasionally accumulates in oysters, clams, and mussels from the Gulf of Mexico and the Atlantic coast of the southern states.

 Ciguatera Fish Poisoning
Ciguatera presents primarily as an acute neurologic disease manifested by a constellation of gastrointestinal (diarrhea, abdominal cramps and vomiting), neurologic (paresthesias, pain in the teeth, pain on urination, blurred vision, temperature reversal) and cardiovascular (arrhythmias, heart block) signs and symptoms within a few hours of contaminated fish ingestion.
In Polynesia, Ciguatera is dominated and initiated by neurologic symptoms (90% of patients report paresthesias and dysesthesia), while reports from the Caribbean suggest that Ciguatera initially presents acutely as a gastroenteritis often with associated cardiovascular symptoms, with the gradual onset and dominance of neurologic symptoms over the first 24 hours.
In the differential diagnosis of Ciguatera, poisoning with the other marine toxins, especially NSP and PSP should be considered since dysesthesias with nausea, vomiting and diarrhea are the presenting symptoms.

 Ciguatera - Wikipedia, the free encyclopedia
Ciguatera is a foodborne illness poisoning in humans caused by eating marine species whose flesh is contaminated with a toxin known as ciguatoxin, which is present in many micro-organisms (particularly, the micro-algae Gambierdiscus toxicus) living in tropical waters.
Due to the localized nature of the ciguatoxin-producing micro-organisms, ciguatera illness is only common in tropical waters, particularly the Caribbean, and usually is associated with fish caught in tropical reef waters.
The symptoms of ciguatera are gastrointestinal distress (nausea, vomiting) followed by neurological symptoms such as headaches, muscle aches, numbness, ataxia, and hallucinations.
