Summary

THE COMBINED EFFECT OF 3 INITIAL LEVELS OF OXYGEN (0, 10, AND 20%), IRRADIATION DOSE (0, 0.5, AND 1 KILOGRAY), AND STORAGE AT 278, 288 AND 298 K (5, 15 AND 25 DEG C) ON TOXIN PRODUCTION BY CLOSTRIDIUM BOTULINUM IN INOCULATED MODIFIED ATMOSPHERE PACKAGED PORK WERE INVESTIGATED. TOXIN WAS DETECTED AFTER ONLY 2 DAYS IN ALL TREATMENTS STORED AT 298 K. AT 288 K, IRRADIATED AND NONIRRADIATED PRODUCT PACKAGED WITH 10 OR 20% HEADSPACE OXYGEN WERE TOXIC AFTER 14 DAYS. FOR PRODUCT PACKAGED WITH 0% OXYGEN AND AN OXYGEN ABSORBENT, TOXIN WAS DETECTED AFTER 21 DAYS IN NONIRRADIATED SAMPLES COMPARED TO 43 DAYS FOR PRODUCT TREATED WITH AN IRRADIATION DOSE OF 1 KILOGRAY. NO TOXIN WAS DETECTED IN ANY PRODUCT STORED AT 278 K, EVEN AFTER 44 DAYS.
