摘要
目的调查2022年甘肃省临夏回族自治州(临夏州)L县发生的一起由毒蘑菇引起的食物中毒事件的流行病学特征及环境因素,为毒蘑菇中毒防控提供依据。方法设计调查表收集病例资料、明确病例定义、开展病例搜索,采集剩余食物样本及现场样本进行基因测序及序列分析。结果本次疫情共发现9例临床病例,现场流行病学调查和实验室检测结果表明,导致本次食物中毒的原因是食用自采的野生蘑菇。检测样本与变红岐盖伞的核酸序列覆盖度为100.00%,一致度为96.06%,属于神经精神型毒蘑菇,是临夏州首次报道变红岐盖伞近似种食物中毒事件。结论此次暴发是由于群众误食野生毒蘑菇变红岐盖伞引起的食物中毒事件,需要进一步加强对群众的野生蘑菇中毒健康教育工作,告知群众不要轻信民间流传的有毒野生蘑菇识别方法,建议在蘑菇中毒高发季节,通过多媒体、公众号、广播电视等方法发出预警,积极宣传不要随意采摘、食用野生蘑菇,谨防食物中毒。
