The objective of the studies was to evaluate survival of Yersinia enterocolitica serotypes 0:3 and 0:9 in freezed pork meat. After 42 days storage of meat samples at —10 and — 20°C live cells of the bacterium were found when an inoculum contained 10⁴ cells of Y. enterocolitica/g. Y. enterocolitica was not found after 28 days of storage of meat at — 10°C and after 35 days of storage at — 20°C when an inoculum contained 10³ of bacterial cells/g. The results point to a better survival of Y. enterocolitica in pork meat stored at — 20°C than in — 10°C.
