A quantitative approach towards a better understanding of the dynamics of Salmonella spp. in a pork slaughter-line

► Dynamics of Salmonella transmission in a pig slaughter-line was investigated. ► Nearly all animals tested Salmonella positive on their skin. ► Prevalence of Salmonella clearly declined at the re-work station. ► Seven different serovars identified; S. Derby and S. Typhimurium most prominent. ► An endemic 'house flora' was present in slaughterhouse studied (S. Rissen).
