Ciguatoxin is found in over 400 species of reef fish. Avoiding consumption of all reef fish is the only sure way to avoid exposure. [31] Imported fish served in restaurants may contain the toxin and produce illness which often goes unexplained by physicians unfamiliar with the symptoms of a tropical toxin.
Rapid testing for this toxin in food is not standard. Some ciguatoxins lower the threshold for opening excitatory voltage-gated sodium channels in the nervous system. Opening a sodium channel causes depolarization, which could sequentially cause paralysis, heart arrhythmia, and changing the senses of heat and cold. Such poisoning from ...
Ciguatoxin 1 or CTX-1 is a toxic chemical compound, the most common and potent type in the group of ciguatoxins. It is a large molecule consisting of polycyclic polyethers that can be found in certain types of fish in the Pacific Ocean. The compound is produced by Dinoflagellates Gambierdiscus toxicus and is passed on through the food chain by ...
The foods are divided into one of four different categories (unprocessed, processed culinary ingredient, processed, and ultra-processed) to help users find, say, the least processed type of ...

Several Gambierdicus species produce potent toxin such as ciguatoxin and maitotoxin, which cause ciguatera fish poisoning. [4] Humans often consume the toxins, as herbivorous fish, which feed on macroalgae, ingest the dinoflagellates. Afterwards, carnivorous fish, which are targeted by fishing industries, move the toxins further up the food chain.
Gambierdiscus toxicus is a species of photosynthetic unicellular eukaryote belonging to the Alveolata, part of the SAR supergroup.It is a dinoflagellate which can cause the foodborne illness ciguatera, [1] and is known to produce several natural polyethers including ciguatoxin, maitotoxin, gambieric acid, and gambierol.
