“…However, neither vacuum‐packaging compared to air storage nor heat‐shock prior to irradiation increased radiation resistance of Y. enterocolitica O:8 (strain ATCC 27729) in ground pork (Shenoy and others ). In raw ground pork stored under modified atmosphere, the mean D 10 ( 137 Cs) for pathogenic Y. enterocolitica serotypes O:3 (strains GER), O:5,27 (strain PT18–1) and O:8 (ATCC 51871) decreased significantly from 0.24 kGy in 100% N 2 to 0.21, 0.19, and 0.16 kGy when 50%, 75% and 100% of N 2 was replaced with CO 2 (Bhaduri and others ). It would seem that CO 2 increases the irradiation sensitivity of pathogenic Y. enterocolitica .…”

Enteropathogenic Yersinia comprising pathogenic Yersinia enterocolitica and Yersinia pseudotuberculosis, are zoonotic pathogens causing foodborne intestinal illness in humans. Y. enterocolitica is common in pork production and pork is associated with infections in humans. Therefore, there is a need to reduce the occurrence and spread of these pathogens within the pork production chain. It would be most effective to control enteropathogenic Yersinia at the farm level. However, at present, feasible intervention methods are lacking and more research is needed. The most effective way to prevent the spread of Y. enterocolitica is to buy piglets from Y. enterocolitica-negative farms. At slaughterhouses, the occurrence of enteropathogenic Yersinia can be reduced but not completely removed by slaughter hygiene and changing slaughter methods. After slaughter, it is difficult to control enteropathogenic Yersinia, since they can survive and even multiply during cold storage and under modified atmosphere. In addition, current knowledge and actions in both domestic and professional kitchens are insufficient for the prevention of yersiniosis. The significance of Y. pseudotuberculosis carried by pigs is uncertain. Although data are still lacking for pathogenic Y. enterocolitica in many aspects, there is even a greater lack of information regarding Y. pseudotuberculosis in pork production. There is a definite need for further research on these pathogens.
