Ciguatera poisoning is the most common foodborne illness caused by a chemical toxin in the United States and is endemic in the Caribbean and Indo-Pacific. Ciguatoxin, produced by a marine dinoflagellate that attaches to algae, is passed up the food chain to large fish and, finally, to humans. The toxin has anticholinesterase activity. The clinical picture is characterized by a variety of gastrointestinal, neurologic and cardiovascular symptoms, usually self-limited. Amitriptyline is reported to be beneficial.
雪卡毒素中毒是美国由化学毒素引起的最常见的食源性疾病，在加勒比地区和印度-太平洋地区呈地方性流行。雪卡毒素由附着在藻类上的海洋双鞭毛虫产生，通过食物链传递给大型鱼类，最终传递给人类。该毒素具有抗胆碱酯酶活性。临床表现以各种胃肠道、神经和心血管症状为特征，通常为自限性。据报道，阿米替林有益。
