1 research, test methods or technical routes 1) 222 samples of pig tonsils, pig carcasses, surface sewage, cutting boards, aprons and so on were collected from the slaughterhouse of Nanjing Roulian Chang Plant. Yersinia enterocolitica was tested in the above The contamination status in the samples was studied. The serotypes and biotype distributions of the isolated strains were also studied. 2) A total of 95 samples of raw fresh pigs, cattle, mutton, fresh fish, frozen frozen poultry meat and raw poultry meat were collected from the farmer’s market to detect the bacteria, and the detected strains were subjected to serum and biochemical typing. 3 Polymerase chain reaction (PCR) technology All the above isolates were subjected to ail, ystA,
