摘　　要：目的了解咸宁市市售食品中食源性致病菌的污染状况,为制定食源性疾病控制的策略提供科学依据。方法按湖北省食品安全风险监测计划要求,2011—2015年采集9类市售的食品样品,依据计划提供的方法和国家标准方法对食品中致病菌进行分离与鉴定。结果 5年共监测样品1 432份,总检出率为14.53%(208/1 432);其中沙门菌为1.05%(15/1 432);金黄色葡萄球菌为4.96%(71/1 432);单核细胞增生李斯特菌为4.69%(52/1 108);蜡样芽孢杆菌为8.98%(68/757);阪崎肠杆菌为1.98%(2/101);大肠埃希菌O157:H7未检出。9类食品中致病菌阳性率最高的为婴幼儿食品(21.78%),其次为热干面(20.14%)和芝麻酱(18.99%)。9类食品中致病菌的检出率差异有统计学意义(χ~2=35.181,P=0.000)。结论咸宁市主要食品遭受不同程度的致病菌污染,以婴幼儿食品遭受蜡样芽孢杆菌污染最为严重,生畜肉、热干面等也遭受到单核细胞增生李斯特菌、金黄色葡萄球菌的污染。因此,有针对性的控制各类食品致病菌的污染,是防止食源性疾病暴发的重要措施。[Objective]To understand the contamination status of food-borne pathogens in commercially available foods in Xianning City,provide scientific basis for making the control measures against food-borne diseases.[Methods]Based on the Food safety risk monitoring plan of Hubei Province,9 kinds of food samples were collected from 2011-2015. The bacteria in the food samples were isolated and identified according to the methods from the plan and the national standard. [Results]A total of 1 432 samples were monitored for 5 years with the total detection rate of 14.53%（208/1 432）. The detection rates of Salmonella,Staphylococcus aureus,Listeria monoeytogenes,Bacillus cereus and Enterobacter sakazakii was 1.05%（15/1 432）,4.96%（71/1 432）,4.69%（52/1 108）,8.98%（68/757） and 1.98%（2/101）,respectively. Escherichia coli O157：H7 was not detected. Among 9 kinds of foods,the positive rate of pathogenic bacteria in infant food was the highest（21.78%）,followed by hot dry noodles（20.14%）and sesame paste（18.99%）. The difference in the detection rate of pathogenic bacteria was statistically significant among nine kinds of foods（χ^2=35.181,P=0.000）. [Conclusion]The commercially available foods in Xianning City have been contaminated by pathogenic bacteria in different degree,and the contamination with Bacillus cereus in infant food is most severe,while Listeria monoeytogenes and Staphylococcus aureus have been detected in raw meat and hot dry noodles. Therefore,targeted measure for controlling the contamination by all kinds of food-borne pathogens is important to prevent the outbreak of food borne diseases.
