摘要:目的: 检测市售鲜奶、乳制品以及肉制品的微生物性污染情况,初步评定当今社会的食品安全系数。方法: 采集200份鲜奶、乳制品以及肉制品样品,经増菌后,分别采用常规培养基检验法测定菌落总数,采用GB/T —2008法进行大肠菌群MPN计数,并按照国家食品安全评定标准对其符合率进行比较分析。结果:%,其中在超市中购买的食品检测合格率(82%)比在集贸市场上购买的食品检测合格率(75%)高。结论: 市售鲜奶、乳制品以及肉制品存在不同程度的细菌污染,但在超市购买比集贸市场上更加安全卫生,同时应该加强食品卫生的监督和管理,为居民群众提供安全的饮食环境。

Abstract: Objective: To detect the microbial contamination mercial milk,dairy products and meat ,and to achive the initial assessment of the food safety Coefficient in today's society. Methods: Collect 200 milk,dairy products and meat samples,Increase bacteria,the test medium were determined by conventional colony count,using GB / T -2008 method MPN to count coliform,and in accordance with the National Food safety assessment Standard pare pliance rates. Results: The overall pass rate of detection is %,of which buying in the supermarket testing pass rate (82%) higher than buying on the qualified rate (75%) .Conclusion: There are different levels of bacterial contamination in mercially available milk,dairy products and meat products,but buying in the supermarket is more health and safety than buying in the fair trade market,at the same time we should strengthen the supervision and management of food hygiene to provide the residents of a safe eating environment.
