  • The incidence of Salmonella in gulls on the Oregon coast

    Creator:
    Berg, Ronald Wayne
    Abstract:
    Environmental swabs and meat samples from two of three seafood processing plants sampled on the Oregon Coast were found to contain Salmonella. Although these enteropathogens were not isolated from the finished products, the danger of contamination is great since the processing received by many seafoods is not designed to yield...

  • Gamma irradiation inactivation kinetics of medically important bacteria contaminating seafoods

    Creator:
    Quinn, Dorothy Jean
    Abstract:
    Gamma irradiation inactivation kinetics were studied using fifteen organisms naturally contaminating seafoods. Survival curves for seven Salmonella, three Shigella, two Streptococcus species and a Staphylococcus, Escherichia and Proteus species were determined using Hartsell's broth and fresh oysters. Also, the Shigella species and one species of Streptococcus, Escherichia and Proteus were...

  • Methods of identifying food poisoning staphylococci

    Creator:
    Orth, Donald Simms
    Abstract:
    Several biochemical tests were studied to determine their correlation with coagulase activity. The lysozyme test was in perfect agreement with the coagulase test for the strains studied. Mannitol fermentation and egg yolk lipase tests were in agreement with the coagulase test for 96% of the coagulase positive strains. Sheep red...

  • The irradiation resistance of food pathogens contaminating seafoods

    Creator:
    Dutiyabodhi, Pisawat
    Abstract:
    Studies have been made to determine the limits of tolerance to gamma radiation for 15 cultures of the following bacterial species both in culture media and in irradiation-sterilized seafoods (crab-meat, halibut and shrimp) inoculated with Salmonella (seven species), Shigella (three species), and one species each of Neisseria, Myco-bacterium, Esctrerichia, Proteus...
