Quick GuideFood Poisoning: 20 Common and Uncommon Types, Signs and Symptoms
What is ciguatera poisoning?
Ciguatera is a type of food poisoning. The ciguatera toxin may be found in large reef fish, most commonly barracuda, grouper, red snapper, eel, amberjack, sea bass, and Spanish mackerel. These fish live in coral reef waters between latitudes of 35 degrees south to 35 degrees north, corresponding to the area located between the Tropic of Cancer and the Tropic of Capricorn. These geographic lines ring the earth north and south of the equator and make up the tropics. These areas include the Caribbean Sea, Hawaii, and coastal Central America.
Ciguatera toxin tends to accumulate in predator fish, such as the barracuda and other carnivorous reef fish, because they eat other fish that consume toxin-producing algae (dinoflagellates) that live in coral reef waters.
Ciguatera toxin is harmless to fish but poisonous to humans. The toxin is odorless and tasteless, and it is heat-resistant, so cooking does not destroy the toxin. Eating ciguatera-contaminated tropical or subtropical fish poisons the person who eats it.
What are the symptoms of ciguatera poisoning?
Symptoms of ciguatera poisoning generally begins six to eight hours after eating the contaminated fish.
- muscle pain,
- abdominal pain,
- dizziness, and
Hot and cold sensation may be reversed.
Severe cases of ciguatera poisoning may result in tearing of the eyes, chills, skin rash, itching, shortness of breath, drooling, and paralysis. Death due to heart or respiratory failure occurs in rare cases.
