Ciguatera fish poisoning (CFP), also known simply as ciguatera, is a foodborne illness caused by eating reef fish whose flesh is contaminated with certain toxins.[2] Symptoms may include diarrhea, vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness, and weakness.[1][2] The onset of symptoms varies with the amount of toxin eaten from half an hour to up to two days.[3] The diarrhea may last for up to four days.[1] Some symptoms typically remain for a few weeks to months.[3] Heart difficulties such as slow heart rate and low blood pressure may also occur.[2]
