摘　　要：目的了解南通市市售食品中食源性致病菌污染状况,为食品安全风险评估和监管提供科学依据。方法按照《南通市食品安全风险监测方案》、《江苏省食品中微生物及其致病因子监测工作手册》要求,2017—2020年共监测了12类1025份食品样品,开展单核细胞增生李斯特氏菌、沙门氏菌、副溶血性弧菌、蜡样芽胞杆菌、金黄色葡萄球菌等致病菌监测,并对结果汇总、分析、评估。结果共检出了142份阳性样品,总阳性率13.85%,2018年阳性率最高(25.65%),2017年阳性率最低(4.98%),肉与肉制品阳性率最高(25.38%),其次是水产及其动物制品阳性率(17.92%),学校周边熟制米面制品阳性率(14.29%),桶装饮用水阳性率最低(2.86%)。从1025份样品中检出了170株致病菌,其中菌株检出率较高的为学校周边熟制米面制品中蜡样芽胞杆菌5株,检出率14.29%;肉与肉制品中金黄色葡萄球菌18株,检出率13.85%;水产及其制品中副溶血性弧菌70株,检出率13.49%;肉与肉制品中单核细胞增生李斯特氏菌16株,检出率12.31%。餐饮环节阳性率要高于流通环节,城市阳性率高于农村。结论各类食品中有不同程度的致病菌检出,食品安全总体态势平稳,今后仍将不断扩大监测范围,加强监测连续性,增加采样数量,提高监测质量,及时掌握该市食品污染变化趋势,做好食品安全预警,同时要加强对食品从业人员食品安全宣教,降低食品污染风险,切实保障该市的食品安全。Objective In order to understand the contamination status of food-borne pathogens in food in Nantong City,and to provide a scientific basis for food safety risk assessment and supervision.Methods The monitoring was performed according to the plan of food safety risk surveillance in Nantong City and the manual on monitoring microbes and its pathogenic factors in foodstuffs of Jiangsu Province.A total of 1025 food samples of 11 kinds were monitored from 2017 to 2020 for detecting of pathogenic bacteria such as Listeria monocytogenes,Salmonella,Vibrio parahaemolyticus,Bacillus cereus and Staphylococcus aureus,and the test results were summarized,analyzed and evaluated.Results A total of 142 pathogenic bacteria were detected,with a total positive rate of 13.85%.The detection rate was the highest in 2018(25.65%),and the lowest in 2017(4.98%).The highest detection rate was found in meat and meat products(25.38%),followed by aquatic products and animal products(17.92%),cooked rice and flour products around the school(14.29%),the detection rate of barreled drinking water was the lowest(2.86%).170 strains of pathogenic bacteria were detected from 1025 samples.The higher positive rate was Bacillus cereus in the cooked rice flour products around the school,and 5 strains of Bacillus cereus were detected,with the detection rate was 14.29%.18 strains of Staphylococcus aureus were detected in meat and meat products,and the detection rate was 13.85%;70 Vibrio parahaemolyticus were detected in aquatic products,and the detection rate was 13.49%;16 Listeria monocytogenes were detected in meat and meat products,and the detection rate was 12.31%.The positive rate of catering links is higher than that of circulation links,and the positive rate of urban areas is higher than that of rural areas.Conclusions Pathogenic bacteria were detected in different kinds of food,and the overall situation of food safety is stable.In the future,the monitoring scope will be expanded continuously,the monitoring continuity will be strengthened,the sampli
