摘　　要：目的检测分析进出境冷冻原肠携带肠出血性大肠杆菌O157∶H7的情况。方法对2010-2011年进境或国产的35份冷冻原肠样品(包括19份冷冻羊原肠和16份冷冻猪原肠)进行检测,根据细菌的培养特性、生化鉴定和血清学鉴定,同时设立标准菌株作为对照。结果 2份原肠样品检出肠出血性大肠杆菌O157∶H7,检出率为5.71%。结论进境和国产原肠均有可能携带肠出血性大肠杆菌O157∶H7,应该加强监测。To study the enterohemorrhagic Escherichia coli （EHEC） O157 ： H7 in entryexit frozen intestines, 35 intestine samples, which included 19 samples derived from lambs/sheep and 16 samples derived from hogs, were collected in imported or domestic products during 2010-2011. Based on bacterial properties, biochemical and serological confirmation, and a EHEC O157 ： H7 reference strain was prepared as well, it shows that 2 frozen intestine samples were contaminated with EHEC O157 ： H7, positive rate was 5.71%. Imported or domestic intestines might be contaminated with EHEC O157 ： H7, the relevant supervision and study should he strengthened.
