DETERMINATION OF RADIATION STERILIZATION DOSE FOR CANNED MEAT. Report No. 13 (Final) for August 1, 1957-November 30, 1959

;
Canned ground beef containing 5.000.000 C. botulinum spores per gram was sterilized with between 3.80 and 3.85 megarad of gamma rays. Higher spore inocula would probably require higher sterilizbtion dosages. Botulinus toxin was regularly found in irradiation-sterilized and incubated cans of ground beef inoculated with 2,670.000 or more C. botulinum 62A spores per gram. The lethality of gamma rays for C. botulinum spores was found to be slightly dependent upon both the temperature during irradiation and the intensity of the radiation field. Canned peas, inoculated with C. botulinum spores, were more easily sterilized with combined irradiation-heat processing than by either form of energy alone. (auth)
