Modelling Salmonella spread within a pig farm under three biosecurity strategies

Résumé

Pork products contribute to human cases of salmonellosis. The Salmonella contamination level of pigs at slaughter age is a critical point in the contamination of the human food chain. The aim of this study was to estimate the number of shedder and carrier pigs at slaughter age under three biosecurity strategies. A stochastic mathematical model was hence developed to simulate the pig population dynamics and the pathogen tr ansmission within a farrow -to-finish herd in which the batch farrowing system was set. We considered, both, the biological variability and the producers’ management that can alter the contact structure and thus, the transmission of Salmonella. The proportion of pigs at slaughter age either carrying or shedding Salmonella was almost twice higher when batch mixing occurred. Our modelling approach allowed us to investigate the magnitude of the effects of biosecurity strategies
