Ciguatera is a type of food poisoning caused by consuming fish contaminated with ciguatoxins. These toxins are produced by certain types of algae that are consumed by small fish, which are then eaten by larger predatory fish. The toxins accumulate in the flesh of these larger fish, such as barracuda, grouper, and snapper, making them dangerous for human consumption.

Symptoms of ciguatera poisoning can include nausea, vomiting, diarrhea, abdominal pain, muscle weakness, and neurological symptoms such as tingling or numbness. In severe cases, ciguatera poisoning can lead to cardiovascular and neurological complications.

There is no specific treatment for ciguatera poisoning, as the toxins are heat-stable and cannot be destroyed by cooking. Management of symptoms typically involves supportive care, such as intravenous fluids for dehydration and medications to control nausea and vomiting.

Prevention is key when it comes to ciguatera poisoning. Avoiding consumption of large predatory fish from tropical and subtropical waters, especially reef fish, can help reduce the risk of exposure to ciguatoxins. It is also important to be aware of local advisories and warnings regarding fish consumption in areas where ciguatera poisoning is more common.

If you suspect that you or someone you know may have ciguatera poisoning, it is important to seek medical attention promptly. While the symptoms of ciguatera poisoning are usually self-limiting and resolve on their own within a few days to weeks, severe cases may require medical intervention. As a medical professional, I recommend staying informed about the risks of ciguatera poisoning and taking precautions to avoid exposure to contaminated fish.
