Summary

SURVIVAL AND GROWTH OF NATURALLY OCCURRING OR INOCULATED BACTERIA WERE STUDIED IN REFRIGERATED: 278 K (5 DEG C), VACUUM-PACKAGED IRRADIATED GROUND PORK. NUMBERS OF NATURALLY OCCURRING MESOPHILES, PSYCHROTROPHS AND ANAEROBES OR FACULTATIVE ANAEROBES WERE REDUCED BY IRRADIATION, WHEREAS LACTIC ACID BACTERIA WERE LEAST AFFECTED. PARTIAL BACTERIAL RECOVERY SUGGESTED SUBLETHAL BACTERIAL INJURY DUE TO IRRADIATION. IRRADIATION PROLONGED SHELF LIFE 2.5-3.5 DAYS IN UNINOCULATED AND 1.0-1.5 DAYS IN INOCULATED MEAT. ADDED SODIUM ACID PYROPHOSPHATE CONTRIBUTED 2 ADDITIONAL DAYS TO INOCULATED, PORK SHELF LIFE BUT HAD NO EFFECT ON THE NATURAL MICROFLORA. LIPID OXIDATION DID NOT INCREASE.
