Summary

BEEF LIVERS FROM FRESHLY SLAUGHTERED CATTLE WERE INOCULATED WITH COAGULASE-POSITIVE STAPHYLOCOCCUS AUREUS AND THEN PLACED IN FROZEN STORAGE. AFTER 14 D OF FROZEN STORAGE, ONE-HALF OF THE LIVERS WERE SUBJECTED TO 294 K (21 DEG C) FOR 24 H FOLLOWED BY A 15-D PERIOD OF STORAGE AT 272 K (-1 DEG C). THE OTHER LIVERS WERE KEPT IN FROZEN STORAGE: 244 K (-29 DEG C) DURING THIS 15-D PERIOD AFTER WHICH ALL LIVERS WERE SUBJECTED TO EITHER 283 OR 294 K (10 OR 21 DEG C) TEMPERATURES. S. AUREUS COUNTS DID NOT CHANGE DURING THE 15-D STORAGE PERIOD AT 272 K, WHEREAS AEROBIC PLATE COUNTS INCREASED BY OVER ONE THOUSAND TIMES.
