A simulation model was developed for exposure assessment of Salmonella during poultry primary processing to assess the effects of different processing steps on the microbial behavior. The model was able to predict the prevalence and number of Salmonella in broilers or their carcasses from arrival to chilling process in a processing plant. Published literature was reviewed, relevant data were complied, and experimental data from challenge tests were fitted to define probability distributions to characterize the incidence and variation of pathogen events affecting the microbial behavior of Salmonella in broilers. Uncertainty analysis was performed using Monte Carlo simulation, separating knowledge uncertainty and stochastic variability.(Download PDF) (Export to EndNotes)
