toxins have been a major problem in Latin America and the Caribbean for years, and now we have become the first laboratory in the region capable of monitoring ciguatera
toxins on-site through the use of nuclear techniques, said Carlos Alonso-Hernandez, Vice Director at the Centre of Environmental Studies of Cienfuegos (CEAC).
Currently there is no reliable, quick test for ciguatera
toxicity in fish, and heat from cooking doesn't inactivate the toxins.
fish poisoning (CFP), caused by the ingestion of predatory reef-dwelling fish harboring ciguatoxins is one of the most commonly reported fish-associated marine intoxications.

Whether the barracudas are a part of a local population or they came from the Caribbean where they are more abundant, it is obvious that the causative agent of ciguatera
may reach high abundances in the northern waters of Yucatan.
toxin is a lipid-soluble, heat-stable marine toxin (2) made by dinoflagellates such as Gambierdiscus toxicus in tropical and subtropical waters.
