Surveillance on aquatic products for Vibrio parahemolyticus,Henan province,2014-2016

目的了解2014~2016年河南省水产品中副溶血性弧菌的污染情况。方法在河南省7个地市的超市、农贸市场、餐饮和批发市场等流通环节,三个季度采集5类水产品913份,按照国家食品污染和有害因素风险监测工作手册和GB 4789.7-2013《食品安全国家标准食品微生物学检验副溶血性弧菌检验》进行采样和检验。结果 913份水产品中副溶血性弧菌的检出率为29.03%,不同年份、不同种类样品间副溶血性弧菌的检出率差异无统计学意义(P>0.05),第三季度检出率为36.03%,明显高于第二季度和第四季度(P<0.01)。批发市场中副溶血性弧菌的检出率高达49.07%,不同流通环节检出率差异有统计学意义(P<0.01)。结论河南省水产品中副溶血性弧菌污染较严重。
