Summary

Vacuum-packaged ground fresh pork samples absorbed gamma radiation doses of 0, 0.57, 1.91, 3.76, 5.52, or 7.25 kilograys at 2 deg C. Samples were analyzed after 1, 7, 14, 21, 28, or 35 days storage at 2 deg C for presence and number of aerobic and anaerobic mesophiles and endospore formers, and aerobic psychrotrophs. Conventional plate counts did not detect surviving microflora in any sample that received an absorbed dose of 1.91 kilograys or higher, even after refrigerated storage for up to 35 days.
