摘要
目的:了解我国进口冻肉产品中小肠结肠炎耶尔森氏菌的检出情况,为此类产品的风险分析和检验检疫工作提供依据。方法:通过采用小肠结肠炎耶尔森氏菌的国标检验方法和VITEK、API生化鉴定仪对247份进口冻肉产品进行检测。结果:247份样品中共检出耶尔森属菌33份,其中17份为小肠结肠炎耶尔森氏菌,检出率为6.88%,均属于生物1A型,其中3株为血清O:8型,其余均属非常见血清型。阳性样品中16份为冻鸡类样品,1份为冻猪肉类样品。94份海产样品无一份检出。结论:通过实验数据分析我国进口的冻肉产品中冻鸡类产品检出小肠结肠炎耶尔森氏菌比率较高,而海产品和冻猪肉产品中检出率相对较低,所以认为冻鸡类产品小肠结肠炎耶尔森氏菌污染风险较高,应加强此类产品检验监管力度。
Objective： To evaluate the presence of Yersinia enterocolitica in the imported goods of frozen raw meat and seafood in China.Methods： All samples were assayed by the national standard method, Strains isolated and identified as Yersinia entercolitica were further analysed for serotype and biotype.Results： From 247 samples including chicken, seafood, pork and turkey, 17 （6.88%） samples were found to be contaminated with Y. enterocolitica. Among the 17 strains of Y. enterocolitica, 16 strains were isolated from chicken, 1 strains were isolated from pork, while no positive result was found in 94 seafood samples.Conclusion： Of all the samples chicken show the highest isolation rate of Y. enterocolitica. The isolation rate of seafood and pork are relatively low.
