While ciguatera is little known in northern latitudes, this foodborne illness remains a persistent public health problem with significant economic consequences for several tropical countries. The objectives of this study were to provide an overview of the trends in this form of ichthyosarcotoxism since 2002 in French Polynesia (FP) and to clarify the link between the severity of the disease and certain environmental etiological factors, such as the diet of the fish consumed. To this end, data from the surveillance program of the Health Directorate and the Louis Malardé Institute were used. The main results of this study show an overall downward trend in ciguatera cases in FP, with a more pronounced incidence in the Tuamotu and Gambier archipelagos. The clinical picture observed remains classic, but cardiac symptoms are more atypical, with a high frequency of hypertension. No link between the severity of the disease and environmental factors was observed. Although a decline in the incidence of this poisoning appears to be real, it is important to maintain ad hoc surveillance of ciguatera and its health effects in French Polynesia. (R.A.)
