【摘要】：目的了解常熟市食品中污染物和有害因素的污染状况,及时发现食品安全隐患,为政府提供决策依据。方法选取当地居民食品主要购买点,共采集1 282份样品,按照各类食品卫生国家标准对食品中食源性致病菌及化学污染物和有害因素进行检测分析。结果食品中菌落总数、大肠菌群超标率分别为16.6%(84/507)和19.9%(101/507),不同类别食品中的菌落总数和大肠菌群超标率差异有统计学意义(χ2=157.2,P0.001;χ2=100.4,P0.001);食品中致病菌检出率为4.2%(34/808),检出的致病菌主要是副溶血性弧菌、金黄色葡萄球菌、蜡样芽胞杆菌、沙门氏菌。酱腌菜中防腐剂、甜味剂超标严重,超标率分别为70.0%(28/40)和40.0%(16/40);海带、紫菜无机砷超标率为72.7%(16/22),蔬菜中存在铅超标;茶叶中农残超标率高,甚至检出禁用高毒农药;水发产品中使用烧碱致p H超标达35.4%(17/48),腐竹中甲醛超标20.0%(3/15)。结论常熟市的食品安全形势总体良好,但也有部分食品中有食源性致病菌和化学污染物污染,相关职能部门应进一步加强监管,并继续做好风险监测工作。
[Abstract]:Objective to investigate the contamination of food pollutants and harmful factors in Changshu City, and to find out the hidden dangers of food safety in time, and to provide the basis for the government to make decisions. Methods A total of 1 282 samples were collected from the main food purchase sites of local residents, and the foodborne pathogenic bacteria, chemical pollutants and harmful factors were detected and analyzed according to the national standards of food hygiene. Results the total number of colonies in food, The rates of exceeding the standard of coliform bacteria were 16.684 / 507 and 19.910 / 501 respectively. There were significant differences in the total number of coliform and coliform bacteria in different kinds of food (蠂 ~ 2157.2n ~ (2) P 0.001; 蠂 ~ (2) 100.4 ~ (4) P _ (0.001); the detection rate of pathogenic bacteria in food was 4.22% ~ 34% ~ 808%, and the main pathogenic bacteria were Vibrio parahaemolyticus, Staphylococcus aureus, Staphylococcus aureus. Bacillus cereus, Salmonella. The preservatives and sweeteners in pickled vegetables exceeded the standard seriously, the rates of exceeding the standard were 70.0% 28 / 40) and 40.010% 40 / 40 respectively, the inorganic arsenic excess rate of kelp and porphyra was 72.7% / 22%, lead exceeded the standard in vegetables, the residual rate of farmers in tea was high, and the high toxic pesticide was even detected. In water hair products, the pH exceeds the standard by using caustic soda to reach 35.4 / 48, and formaldehyde in humus exceeds the standard by 20.0 / 3 / 15. Conclusion the food safety situation in Changshu City is good in general, but there are some foodborne pathogenic bacteria and chemical pollutants in some foods.
