ciguatera

 [se″gwah-ta´rah]
a form of fish poisoning, marked by gastrointestinal and neurologic symptoms due to ingestion of tropical or subtropical marine fish such as the barracuda, grouper, or snapper that have ciguatoxin in their tissues.

ci·gua·te·ra

(sē'gwă-tār'ă),
An acute toxic syndrome with predominantly gastrointestinal and neuromuscular features induced by ingestion of the flesh or viscera of various marine fish of the Caribbean and tropic Pacific reefs that contain ciguatoxin. The lipid-soluble, heat-stable toxin is produced by the dinoflagellate Gambierdiscus toxicus, which is epiphytic on red and brown algae. Herbivorous fish foraging on reef algae consume the flagellates and are in turn consumed by carnivorous fish, the toxin becoming increasingly concentrated as it passes up the food chain. Some 400 species of fish have been associated with human intoxication. Symptoms come on 3-12 hours after exposure and include vomiting and diarrhea, myalgia, dysesthesia and paraesthesia of the extremities and perioral region, pruritus, headache, weakness, and diaphoresis. Toxic effects usually resolve spontaneously in about 1 week.

Ciguatera 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.
Ciguatera 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.
