  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.

The toxins are known to originate from several dinoflagellate (algae) species that are common to ciguatera endemic regions in the lower latitudes.
Ciguatera poisoning is usually self-limiting, and signs of poisoning often subside within several days from onset.

 Ciguatera Fish Poisoning   (Site not responding. Last check: 2007-10-25)
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.
