摘要
目的了解北京市昌平区主要消费食品中食源性致病菌的污染状况,寻找引起食源性疾病的重点食品,对可能发生的食源性疾病进行预测和预报。方法 2011—2012年采集昌平区市售14类共275件食品样品进行10种食源性致病菌的分离与鉴定。结果 275件样品中共检出致病菌17株,总检出率为6.18%。生肉类和鲜冻水产品污染最为严重(20.00%),其次是生食动物性水产品(11.76%)。金黄色葡萄球菌的检出率为6.93%,副溶血性弧菌检出率为1.85%,其他致病菌未检出。结论生肉类、鲜冻水产品和生食动物性水产品是北京市昌平区市售食品的主要污染品种,金黄色葡萄球菌、副溶血性弧菌是污染食品的主要致病菌。

[ Results] A total of 17 strains of pathogens （6.18% ） were isolated. The polluted status in raw meat and fresh frozen aquatic products were t most serious（ 20.00% ） , followed by the raw food animal aquatic products[ 11.76% ）. The positive rates of Staphylococcus aureus was 6.93% , that of vibrio parahemolyticus was 1.85% , other pathogenic bacteria were not detected.
