Ciguatera fish poisoning (CFP), also known as ciguatera, is a foodborne illness caused by eating reef fish contaminated with ciguatoxins. [ 4 ] [ 2 ] Such individual fish are said to be ciguatoxic . Symptoms may include diarrhea , vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness , and weakness.
Such poisoning from ciguatoxins is known as ciguatera. Ciguatoxins are lipophilic , able to cross the blood–brain barrier , and can cause both central and peripheral neurologic symptoms. The major symptoms will develop within 1–3 hours of toxin ingestion: vomiting, diarrhea, numbness of extremities, mouth and lips, reversal of hot and cold ...
The symptoms of acute ciguatera fish poisoning can already start 30 minutes after eating contaminated fish. [3] [11] However, in milder cases the first symptoms arise 24 to 48 hours later.

Eating fish containing a high enough dose of CTX-1 causes Ciguatera Food Poisoning (CFP). It is suspected that concentration of 0.08 ug/kg fish is high enough to cause clinical symptoms and concentrations over 0.1 ug/kg fish are considered a health risk. [ 15 ]
The finding is gaining attention in the scientific and fishing communities because gambierdiscus is contained in a toxin that causes a type of food-borne illness called ciguatera.
Afterwards, carnivorous fish, which are targeted by fishing industries, move the toxins further up the food chain. Ciguatera is the most common form of seafood poisoning caused by harmful algal blooms in the world and its incidence and range appear to spread. Best estimates indicate that more than 50,000 people are globally affected every year.
