Canned shelf-stable luncheon meat containing varying amounts of sodium nitrite, prepared according to a commercial formula, was processed at 110°C to Fo = 0.4 and held at 35°C until nitrite was no longer detectable. The meat was then inoculated wit

Spores of Clostridium botulinum strains 13983B and 62A were heated at pH 6.0, 6.5 or 7.0 in M/15 phosphate buffer at 110 C (230F) to Fo = 0.01, 0.1, 0.3, and 0.6. The spores that survived were enumerated in media of the same pH as the buffer in which

A strain of Clostridium perfringens type D was grown in a complex medium with or without pH control. Rate and extent of growth was the same without pH control and at controlled pH levels between 6.0 and 7.4, but was reduced at pH 7.6. With controlled

Salmonellae were isolated from naturally infected swine and human feces by means of selective migration through semisolid enrichment (SM) media in modified “U” tubes. Comparative studies showed that recovery of Salmonella by SM techniques was equ

Bacterial counts are valueless as a measure of the degree of spoilage in fresh fillets.There is a very close correlation between the number of psychrophilic gram-negative organisms on fillets and their keeping time in cold storage. This correlation d

Glucose and dextrin were compared for their ability to support toxinogenesis in cultures of strain D7 of Clostridium perfringens type D with pH controlled at 7.0 or uncontrolled. At pH 7.0 both carbohydrates supported toxinogenesis equally: the yield
