WebJun 1, 2002 · C. perfringens spores pre-heated to 100 °C for 60 min were found to be heat-resistant, but upon germination, the resultant vegetative cells sporulated poorly, whereas spores heated to 70 °C for 10 min were far less heat resistant, but had subsequently increased sporulation potential of the vegetative cells ( Nishida, Seo & Nakagawa, 1969 ). WebThe significant outputs of our studies are: spore heat resistance is critical for C. perfringens to cause foodborne illness; thoroughly cooking food is the best approach to prevent and control C. perfringens type A foodborne illness; rapid cooling of cooked foods and then storing and serving these foods at nonpermissive conditions for ... highland homes corporate office dallas
