Validation of predictive mathematical models describing the growth of Escherichia coli O157:H7 in raw ground beef.

Type of article: Article

Summary

The growth of Escherichia coli O157:H7 in raw ground beef was investigated at 12, 20, and 35 deg C at pH 5.7 (unadjusted) and adjusted to pH 6.3 to 6.4. These growth data were fitted to the Gompertz equation and the resulting growth kinetics were compared with predictions from the US Department of Agriculture Pathogen Modeling Program. Close agreement with the model was obtained at pH 5.7, but at pH 6.4, growth was more rapid than predicted.
