The aim of this study was to evaluate the performances of two growth models for prediction of
Salmonella Enteritidis in ground beef, namely the extended logistic model and the ComBase web
edition Baranyi model. Performances of the growth models were evaluated by using various statistical
criteria, namely the square root of the mean of the square error (RMSE), calculation of the residuals,
and student T. test. It was found that both models described well the growth curves for Salmonella
Enteritidis at various initial doses, constant and dynamic temperatures. In addition, no significant
differences were observed between the estimated values of data points at various initial doses and at
constant and dynamic temperatures with the two models (p>0.05) except at the initial dose of 2 log
(CFU/g) that was significant (p
