This study established a predictive model for the reduction of cross-contamination of Salmonella on chicken during the chilling process. A Normal (0.75, 0.1) distribution model describes the bacterial reduction in the chilling process and a Triangle (2.5,1.5,1.1) distribution describes the logarithm of transfer rate. For prediction of post-chill incidence, the developed response surface model has a satisfactory performance, which can be used to provide input for the QMRA model of Salmonella in poultry supply chains in China.
