ciguatera

poisoning by consumption of the flesh or viscera of sporadically toxic tropical predatory fish of a wide range of species. The causative heat-stable toxins (ciguatoxin, maitotoxin and others) originate in the dinoflagellate (Gambierdiscus toxicus) and possibly others or from associated bacterial microflora. The toxins are subject to bioaccumulation in fish which eat the dinoflagellates, and subsequently in the predators. Growth of the dinoflagellates is promoted by the destruction of their coral reef habitat. Poisoning characterized by vomiting, diarrhea and paresis in cats, dogs, humans. See also lyngbya.
