Comparison of net growth of Shiga toxin-producing Escherichia coli strains of serogroups O26, O103, and O157 in ground meat at different temperatures

Abstract

In this study, the net growth of 22 Shiga toxin-producing Escherichia coli O26, O103, and O157 strains originating from risk foods, animal feces, and patients suffering from hemolytic-uremic syndrome was compared in ground beef at 15 and 37 °C. The results of this study demonstrated that the ability to grow to high numbers in ground meat at these temperatures is strain-specific rather than serogroup- or origin-specific.
