十堰市2000～2006年食源性致病菌监测分析

目的：了解十堰市2000～2006年食源性致病菌污染及分布状况。方法：用增菌、培养、分离、血清学、API生化学对病原菌进行鉴定。结果：平均检出率为11.87%,乳制品和冷饮均未检出致病菌,其次是熟肉制品检出率最低,为2.35%,猪肉制品检出率最高,为22.22%;2002年检出率最低,为3.26%,2004年检出率最高,为20.00%;市乳品公司生产的45份样品均未检出病原菌,其次是餐饮业检出率最低,为7.69%,农贸市场检出率最高,为15.31%;7年共检出病原菌64株,沙门菌检出率最高,5.75%,空肠弯曲菌均未检出,其次是肠出血性大肠杆菌（O157）为2.04%;检出菌构成比沙门菌占48.43%,单核细胞增生李斯特菌占26.56%,肠出血性大肠杆菌（O157）占17.19%,副溶血性弧菌占7.81%,空肠弯曲菌0.00%。结论：我市食品中不同程度受到沙门菌、单核细胞增生李斯特菌、肠出血性大肠杆菌（O157）、副溶血性弧菌的污染,O157为我市新发病原菌,尤以生畜禽肉、蔬菜沙拉、非发酵豆制品污染严重。
