新疆阿拉尔垦区部分肉和肉制品的细菌学评价

Evaluation of meat and meat product by bacteriologica in Alar area of Xinjiang

目的:对阿拉尔地区部分肉及肉制品进行细菌学评价,为消费者提供健康和安全的饮食标准。方法:对新疆阿拉尔片区部分肉制品进行随机抽样,分别进行细菌菌落总数和大肠菌群的测定,并将分离的细菌进行血清学鉴定和动物回归试验,观察所分离的大肠杆菌的致病力。结果:检测结果表明:该地区部分肉及肉制品的细菌菌落总数和大肠菌群与国标的细菌菌落总数和大肠菌群(MPN)对比得出:新鲜生肉、卤肉的细菌菌落总数合格率均为100%,大肠菌群(MPN)合格率分别为100%和80%,通过血清学鉴定和动物回归试验表明生肉和卤肉中分离的部分大肠杆菌有很强的致病力。结论:虽然该地区的肉及肉制品的细菌菌落总数和大肠菌群的合格率平均为80%,但是动物回归试验显示所分离的部分大肠杆菌仍具有很强的致病力,因此可见该地区部分肉及肉制品安全性还是令消费者担忧的。

Objective：To evaluate the meat and meat product in the Alar area to provide a standard of quality and safety for consumer. Methods：Samples were randomly selected for measuring the GB eode＇s total bacterium colony and the large intestine bacteria colony （MPN） in the meat and the meat product of Alar area. The serology and the return animal experiments were earried out to detect the E. coli which separated from the raw meat and the halogen meat and watched the pathogenesis. Results：The experiment results showed that the fresh meat and halogen meat total bacterium colony qualified rate was 100%, the large intestine bacteria colony （MPN） the qualified rate respectively was 100% and 80%. Conclusion：The average quality in the total bacterium colony and the large intestine bacteria colony （MPN） are 80%, but in the serology and the return animal experiments the E. coli separated from the raw meat and the halogen meat has stronger pathogenesis.
