The diagnosis is supported by detection of ciguatoxin in the implicated fish.
More than 80% of the seafood-related outbreaks were caused by scombrotoxin or ciguatoxin, heat-resistant toxins found in warmwater species of fish.
Chemical agents caused 45 outbreaks (264 cases): ciguatoxin caused 13 outbreaks (43 cases), and scombrotoxin caused 13 outbreaks (27 cases).
The egg microinjection method had already been used to characterize the adverse effects of known bioaccumulants such as ciguatoxin (a related polyether toxin also produced by a dinoflagellate) and the pesticide DDT in medaka fish.
This method has previously been used to characterize the adverse effects of ciguatoxin and chemical contaminants such as DDT (19,20).
