鲀毒鱼毒素检测及物种鉴定技术研究进展

Recent Advances in Techniques for Tetrodotoxin Detection and Species Identification of Tetrodotoxic Fish:A Review

鲀毒鱼引起的河鲀毒素(tetrodotoxin,TTX)中毒是中国沿海地区食物中毒致死的主要原因之一。河鲀毒素中毒发病迅速,至今尚无特效药,因此,通过检测TTX含量或鉴定携带TTX的物种可以更好地进行TTX中毒的风险分析、管理和控制。本文综述了鲀毒鱼TTX的检测技术以及鲀毒鱼物种鉴定的方法,以期能预警并减少鲀毒鱼引起的食物中毒事件,或在中毒事件发生后,能迅速判断中毒原因以便于施救;此外,提出了对未来河鲀毒素检测技术、鲀毒鱼物种鉴定方法的展望。本文对预防河鲀中毒事件的发生以及合理利用河鲀资源具有一定的意义。

Tetrodotoxin(TTX)poisoning caused by consumption of puffer fish is one of the major causes of death related to food poisoning in coastal areas of China.Tetrodotoxin poisoning occurs rapidly,and there are no specific antidotes at present.Therefore,detecting the content of TTX or identifying the species of puffer fish as a source of TTX is useful for better analysis,management and control of the risk of TTX poisoning.In this article,the detection techniques of TTX and the methods for species identification of tetrodotoxic fish are reviewed,which could be of great significance for preventing puffer fish poisoning and rational utilization of puffer fish resources,and future prospects are discussed.We hope that this review will help early warn and reduce food poisoning caused by puffer fish and promptly identify the cause after it happens.
