Summary

SURVEY OF COMMERCIALLY AVAILABLE VACUUM-PACKAGED FRESH PORK HELD AT 278 K (5 DEG C) FOR 7, 14, 21 AND 28 DAYS, AND OF FOUR VACUUM-PACKAGED LEG ROASTS STORED FOR 21 DAYS AT 278K THEN FOR 90 DAYS AT 255K (18 DEG C) BEFORE SAMPLING. SURFACE CORES OF MEAT WERE ENRICHED IN SORBITOL BILE BROTH 21 DAYS AT 278K TO ENHANCE RECOVERY OF YERSINIA ENTEROCOLITICA ON PECTIN AGAR. OF THE 54 SAMPLES SURVEYED, 20% YIELDED HIGHLYPECTINOLYTIC COLONIES OF AEROMONAS HYDROPHILA THAT WERE CYTOTOXIC TO Y1 AND HELA CELLS, 6% YIELDED Y. ENTEROCOLITICA AND 6% YIELDED YERSINIA INTERMEDIA. YERSINIA WAS RECOVERED FROM BOTH FRESH AND FROZEN SAMPLES. THIS IS BELIEVED TO BE THE FIRST REPORT OF PECTINOLYSIS BY A. HYDROPHILA AND RECOVERY OF CYTOTOXIC A. HYDROPHILA FROM VACUUM-PACKAGED PORK.
