Radiation Sterilization of Food..: II. Some Aspects of the Growth, Sporulation, and Radiation Resistance of Spores of Clostridium Botulinum, Type E
The radiation resistance of spores of 6 strains of Type E C. botulinum in beef stew was determined. The results were evaluated in terms of the minimum dose showing no spoilage for a 2 billion total inoculum level (20 cans each with l00 million spores per can) and in terms of a calculated radiation D value. The mean radiation D value for 6 strains was 0.132 megarad (range Type A and 5 strains of Type B showed that Type E strains possessed about 45-55% of the resistance to ionizing radiation of Types A and B. It was 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. (H.H.D.)
