The radiation resistance of spores of 6 strains of Type E Clostridiunw botulinum was determined in a beef stew substrate. The results are evaluated in terms of the minimum dose showing no spoilage for a 2 billion total inoculum level (20 cans each with 100 million spores per can) and in terms of a calculated radiation D value. The mean radiation D value for 6 strains is 0.132 megarad (range 0.125to 0.138). A comparison with results for 6 strains of Type A and 5 strains of Tyne B shows that Type E strains possess about 45 to 55% of the resistance to ionizing radiations of Types A and B. It is concluded that any radiation dose for food sterilization based upon the maximum resistance of Type A or B strains would provide ample protection against Type E strains. The unswelled cans at the lowest radiation level showing no spoilage were free of toxin and recoverable Type E spores. (Publ. Health Eng. Abstr.).
