Abstract Salmonella is one of the most pathogenic bacteria known. In the present study,to predict Salmonella growth during chilled storage of raw fresh pork, a single strain of Salmonella was used to investigate and model its growth on pork slices. Kinetic data for the pathogen’s growth on fresh pork slices at refrigeration temperature (4, 7, 10, 12 and 15℃) were ift to Gompertz, Logistic, Richards and MMF models using Curve Expert 1.4 software. The results indicated that the Richards model was optimal at 7 and 10℃with a correlation coefifcient (r) of 0.996 9 and 0.994 0 respectively, while the MMF model was optimal at 12 and 15℃with an r value of 0.997 4 and 0.998 2 respectively. No single model could give a consistently preferable goodness-of-ift for all growth data. This study can provide theoretical guidance for identifying the consumption safety of raw fresh pork.
