江西省一起食用亚稀褶红菇中毒引起死亡事件的调查与溯源

Investigation and tracing of the mushroom poisoning caused death case by Russula subnigricans in Jiangxi Province

目的调查并溯源2020年9月江西省一起误食有毒蘑菇中毒引起死亡事件的情况,为预防类似事件的发生提供参考。方法采用访问调查法进行流行病学描述性分析并初步判断,对收集的有毒蘑菇样品进行形态学和分子生物学鉴定。结果流行病学调查发病患者均食用了野生蘑菇,未食用者未发病,平均潜伏期19 min,病情进展迅速,出现恶心、呕吐等症状,对肝肾和心脏功能造成损害,致死率较高。有毒蘑菇样品经形态学、分子生物学比对鉴定为亚稀褶红菇。结论本次事件为江西省报道的一起误食亚稀褶红菇引起中毒死亡的事件,提示江西省毒蘑菇中毒形势较为严峻,相关部门需要加强防控,预防类似事件发生。

Objective This study aimed to provide a reference for preventing the occurrence of events similar to the mushroom poisoning case by Russula subnigricans that caused the death of individuals in Jiangxi Province in September 2020 by investigation and tracing.Methods Epidemiological descriptive analysis was used to make a primary judgment.Then,morphological and molecular biological identification were carried out on the collected mushroom samples.Results The epidemiological information indicated that all the patients ate the wild mushroom,while those who did not eat the mushroom did not get sick.The average incubation period was 19 min,which suggested that the disease progressed rapidly.Symptoms such as gastrointestinal discomfort and vomiting were observed.The liver,kidney,and heart functions were damaged,and the mortality rate was high.The morphological and molecular studies identified the samples as Russula subnigricans.Conclusion This incident is a reported poisoning death event in Jiangxi Province caused by eating Russula subnigricans by mistake,which indicates that the poisoning situation of poisonous mushrooms in Jiangxi Province is relatively serious,and relevant departments need to strengthen prevention and control efforts to prevent similar incidents.
