目的了解内蒙古通辽市消费量大、流通广的食品中主要食源性致病菌的污染情况,进行食品风险评估,确立风险管理决策,降低人群食源性疾病的发病率。方法依据国家食品污染和有害因素风险工作手册上的方法。结果2009年-2013年在通辽市农贸市场、超市、生产厂家、批发场所、食品专卖店等地采集16种食品,共1 284份,检测12种食源性致病菌,检出食源性致病菌151株,检出率为11.76%,其中地产食品—生畜肉检出率为33.59%、生禽肉检出率为29.89%、动物性水产品检出率为18.89%、米面制品检出率为16.98%,主要以单核细胞增生李斯特菌、副溶血性弧菌、蜡样芽孢杆菌污染最严重。膨化食品、蛋糕、水果、蔬菜类食品未检出致病菌。包括散装食品865份,检出率为13.76%;定型包装食品419份,检出率为6.92%。结论食品中存在的致病菌对人群构成潜在健康危害,应加强卫生监管、监测,预防食源性疾病的发生。 Objective To understand the pollution of major food-borne pathogenic bacteria in Tongliao City, Inner Mongolia, which is characterized by high consumption and wide distribution, to conduct food risk assessment, establish risk management decision-making and reduce the incidence of food-borne diseases. The method is based on the approach of the National Risk Food Handbook on Food Contamination and Hazard Factors. Results From 2009 to 2013, 16 kinds of foods were collected from Tongliao City farmer’s market, supermarkets, manufacturers, wholesale establishments, food stores and other places, with a total of 1 284 samples. 12 food-borne pathogens were detected, 151 strains of pathogens, the detection rate was 11.76%, of which 33.59% of real estate food - raw meat, the detection rate of raw poultry was 29.89%, the detection rate of animal aquatic products was 18.89%, rice product inspection The rate of 16.98%, mainly Listeria monocytogenes, Vibrio parahaemolyticus, Bacillus cereus the most serious pollution. Puffed foods, cakes, fruits, vegetables, no detectable pathogens. Including bulk food 865, the detection rate was 13.76%; 419 packaged food, the detection rate was 6.92%. Conclusion The pathogens present in food pose a potential health hazard to the population. Health supervision, monitoring and prevention of foodborne diseases should be strengthened.
