2010～2016年北京市大兴区食品中食源性致病菌污染状况分析

The survey of food contamination status caused by food-borne pathogens from 2010 to 2016 in Daxing,Beijing

目的通过对北京市大兴区市售食品食源性致病菌污染状况的分析总结,为食源性疾病的监测、预防、控制提供科学依据。方法对2010~2016年在大兴区辖区内采集的1272件样品进行研究,严格遵守《全国食源性致病菌监测工作手册》的操作流程,对样品中的6种食源性致病菌(蜡样芽孢杆菌、沙门氏菌、金黄色葡萄球菌、单增李斯特菌、副溶血性弧菌、创伤弧菌)进行检测分析。结果 2010~2016年连续7年共检出食源性致病菌82株,污染样品检出率为6.45%。在检出的82株致病菌中,单增李斯特菌、沙门菌、金黄色葡萄球菌、副溶血性弧菌、创伤弧菌、蜡样芽孢杆菌检出率的构成比分别为42.68%、18.29%、9.76%、17.07%、4.88%和7.32%。结论本研究样品中,首要污染的致病菌为单增李斯特菌,主要受污染食品为生畜肉,食品安全监管部门应当增大对食品安全的监管力度,进一步预防和控制食源性疾病的发生。

Objective To investigate the occurrence of food-borne pathogenic bacteria in retail foods in Daxing area and provide scientific basis for monitoring,prevention and control of food-borne diseases.Methods Studied on 1272 samples collected in Daxing District area from 2010 to 2016.In accordance with the standard operating procedure from the"national food-borne pathogens monitoring manual",and six food-borne pathogenic bacteria(bacillus cereus,salmonella,staphylococcus aureus,listeria monocytogenes,vibrio parahaemolyticus and vibrio vulnificus)were tested and analyzed.Results From 2010 to 2016,82 strains of food-borne pathogenic bacteria were detected for 7 years in a row.The detection rate of contaminated samples was 6.45%.In 82 strains of pathogenic bacteria detection,the listeria monocytogenes,salmonella,staphylococcus aureus,vibrio parahaemolyticus,vibrio vulnificus and bacillus cereus,salmonella detection rate than respectively 42.68%,18.29%,9.76%,17.07%,4.88%and 7.32%.Conclusion In this study sample,the primary contaminant is listeria monocytogenes,mainly contaminated food is raw meat.The food safety supervision department should increase the supervision of food safety and further prevent and control the occurrence of food-borne diseases.
