SUMMARY Spore recovery counts made on five strains of Clostridium botulinum indicated striking differences in radioresistance. Strain 12885A was most resistant, and strain 32B least resistant. A difference was noted in the survival of spores in five food products (green beans, chicken, codfish, pork, and beef), with green beans providing the most destruction. It was also observed that a given substrate was found to allow a greater per cent survival of one strain than another, so that two strains compared in one food do not always show the same relationship as when compared in another food. Some evidence indicates a modest recovery of viability of the irradiated spores during frozen storage prior to culturing. Since the character of the food determines in part the dose required for the destruction of Cl. botulinum , no single dose would be best for all food products.
