Type of article: Article

Summary

In the presence of no or low background flora, there was growth of the strains at 8 deg C. High background flora in ground beef inhibited growth at this temperature. In the foods held at low temperatures, only small amounts of verotoxin were detected; however, even at the optimum 37 deg C, there was still relatively little verotoxin formed. Even under nongrowth conditions, the strains remained viable.
