Toxin Production by Clostridium Botulinum Type E in Radiation Pasteurized Fish

概要

Herring homogenates were inoculated with 10<SUP>5</SUP> spores of Clostridium botulinum type E per gram, irradiated at 0, 0.1 and 0.3 Mrads and then stored at 20°C or 10°C. Total volatile base, total bacterial counts, and oxydation-reduction potential were periodically examined and the relation between these indices in irradiated samples was compared with that in unirradiated ones.<BR>Toxin production in unirradiated samples occurred so rapidly that there seems to be no significant difference between the time for development of toxin and the spoilage time, whilist toxin production in irradiated samples began to occur before the appearance of signs of spoilage. In addition, more toxin was produced in irradiated samples than in unirradiated ones.<BR>The fact that radiation pasteurization apparently enhances the growth and toxin production of Clostridium botulinum type E in herring homogenates was further discussed from the view of oxydation-reduction potential.
