A type of poisoning caused by eating fish whose flesh contains ciguatoxin, a substance that is probably obtained initially from marine cyanobacteria eaten by small fish, in turn eaten by larger fish in which the toxin accumulates. The symptoms include nausea, vomiting, numbness of parts of the body, and even coma. Sometimes, therefore, it is probably wise not to eat certain species (e.g. mackerel, grouper, jack, and snapper).
