【摘要】：目的了解资阳市市售食品微生物污染情况,为开展食品安全风险评估与预警及制定有效的食品安全监管措施提供依据。方法按照《四川省食品安全风险监测实施方案》、《食品卫生微生物学检验》(GB4789)和《国家食品污染和有害因素风险监测工作手册》要求,采集资阳市市售食品17类559件,开展金黄色葡萄球菌等10种食源性致病菌检测,并对其中13类289件食品开展一般卫生指标检测。结果 2012-2016年共开展13类289件食品一般卫生指标检测,不合格率为43.94%(127/289),主要不合格食品类别有自制饮品、桶装饮用水、果蔬及沙拉类和散装糕点等即食食品。共开展17类559件食品常见食源性致病菌检测,不合格率16.10%(90/559),有11件生肉类样品同时检出2种(株)致病菌。共检出7种101株食源性致病菌,蜡样芽孢杆菌检出率最高,阳性菌株构成比显示金黄色葡萄球菌居首位。五年食源性致病菌检测不合格率0%~33.3%,一般卫生指标不合格率20%~68%。结论资阳市市售食品受到不同程度食源性微生物污染,即食食品卫生状况差,生肉类食品致病菌污染严重,食源性致病菌检测不合格率逐年增长。
[Abstract]:Objective to investigate the microbial contamination of food sold in Ziyang City, and to provide basis for food safety risk assessment and early warning and effective food safety supervision measures. Methods according to the requirements of Sichuan Province Food Safety risk Monitoring Program, Food Hygiene Microbiology Test (GB4789) and the National Manual of Food pollution and harmful factors risk Monitoring, we collected 559 food products of 17 kinds sold in Ziyang city. Ten kinds of foodborne pathogenic bacteria such as Staphylococcus aureus were detected and the general hygienic indexes were detected for 289 foods of 13 categories. Results from 2012 to 2016, 289 food samples of 13 categories were tested, the unqualified rate was 43.94% (127 / 289). The main unqualified food categories were homemade drinks, bottled drinking water, fruits and vegetables, salad and bulk pastry and other ready-to-eat foods. A total of 559 common foodborne pathogens were detected in 17 kinds of 559 food samples. The unqualified rate was 16.10% (90 / 559), and 11 samples of raw meat were detected with 2 strains of pathogenic bacteria at the same time. The detection rate of Bacillus cereus was the highest, and the composition of the positive strains was the highest in the proportion of Staphylococcus aureus. The unqualified rate of foodborne pathogenic bacteria in 5 years was 33. 3%, and the unqualified rate of general health index was 20. 68%. Conclusion the food on sale in Ziyang city is polluted by foodborne microorganism, the hygienic condition of ready-to-eat food is poor, the contamination of pathogenic bacteria of raw meat food is serious, the rate of unqualified detection of foodborne pathogenic bacteria is increasing year by year.
