Abstract
Historical records of ciguatera in Mexico date back to 1862. This review, including references and epidemiological reports, documents 464 cases during 25 events from 1984 to 2013: 240 (51.72%) in Baja California Sur, 163 (35.12%) in Quintana Roo, 45 (9.69%) in Yucatan, and 16 (3.44%) cases of Mexican tourists intoxicated in Cuba. Carnivorous fish, such as snapper (Lutjanus) and grouper (Epinephelus and Mycteroperca) in the Pacific Ocean, and great barracuda (Sphyraena barracuda) and snapper (Lutjanus) in the Atlantic (Gulf of Mexico and Caribbean Sea), were involved in all cases. In the Mexican Caribbean, a sub-record of ciguatera cases that occurred before 1984 exists. However, the number of intoxications has increased in recent years, and this food poisoning is poorly studied in the region. Current records suggest that ciguatera fish poisoning in humans is the second most prevalent form of seafood poisoning in Mexico, only exceeded by paralytic shellfish poisoning (505 cases, 21 fatalities in the same 34-year period). In this study, the status of ciguatera in Mexico (epidemiological and treatment), and the fish vectors are reviewed. Dinoflagellate species Gambierdiscus, Ostreopsis, and Prorocentrum are related with the reported outbreaks, marine toxins, ecological risk, and the potential toxicological impact.

We review the status of ciguatera in Mexico from 1984 to 2013, the fish vectors implicated, and the potential causative dinoflagellates (Gambierdiscus spp., Ostreopsis spp., and Prorocentrum spp.)
There have been 464 CFP intoxication cases over 25 separate outbreaks recorded in Mexican coastal zones between 1984 and 2013: 240 (51.72%) in Baja California Sur, 163 (35.12%) in Quintana
Summary
Ciguatera fish poisoning (CFP) is a food-borne illness endemic to tropical and subtropical waters. The true incidence of CFP is difficult to ascertain due to under-reporting of CFP-related symptoms (2 to 10%) to health authorities [6]. Mar. Drugs 2019, 17, 13; doi:10.3390/md17010013 www.mdpi.com/journal/marinedrugs. Other benthic dinoflagellate species of the genus. Ostreopsis produce Palytoxin-like compounds (PTX) and some Prorocentrum species produce okadaic acid and its analogs (diarrheic shellfish toxins), which have been associated with ciguatera [5,22]. We review the status of ciguatera in Mexico (epidemiological and treatment) from 1984 to 2013, the fish vectors implicated, and the potential causative dinoflagellates (Gambierdiscus spp., Ostreopsis spp., and Prorocentrum spp.)
