河南省2011年生食水产品监测结果分析

Analysis on health monitoring results for raw aquatic foods in Henan Province in 2011

目的:了解河南省生食水产品卫生状况,指导消费,防止因食用生食水产品而引起食源性疾病。方法:随机采集河南省18个地市73家餐饮单位生食水产品192份,采用国家标准方法进行菌落总数、大肠菌群、致病菌、寄生虫囊蚴、异尖线虫和24种抗生素检测。按照国家标准及农业部193、235号公告对生食水产品进行评价,并将日本生食水产品卫生标准与GB10136-2005进行比较。结果:所检项目都合格的样品占总抽查量的15.1%,其中菌落总数、大肠菌群、致病菌、寄生虫囊蚴及异尖线虫合格率分别为23.4%、25.5%、95.8%、100%、100%,抗生素合格率为100%,检出率为5.73%。不同品种生食水产品、大中型饭店生食水产品合格率差异均无显著性(P>0.05)。结论:河南省生食水产品普遍存在微生物污染,应加强生食水产品在其生长水域及运输、存放、加工等环节的监管力度。
