Salmonellosis is an infectious disease whose main clinical manifestation is acute gastroenteritis caused by consumption of contaminated water or food especially meat. The aim of this study was to determine the Salmonella spp. prevalence inside pork and the environment from 6 slaughterhouses and 14 butcher's shops all of them selected in Tolima region. A convenience study was realized, choosing slaughterhouses depending on animal reception charge and the good manufacture practices. Sample were obtained (n=507) from environment samples were realized smears on knives, tables, hooks, waste pipes, floors, and transportation trucks. Samples were under microbiologic analysis for Salmonella isolation, which was identified by biochemical and serological test (Poli A +Vi). The results showed a prevalence of Salmonella spp. of 4.93% (25/507). 14 out 25 positives (56%) were isolated from carcass and 11 remaining (44%) were isolated from environment; in slaughterhouses as well as butcher's shops. In conclusion, Isolation of Salmonella spp. in post-production phases can be due to cross contamination with environmental fomites in transport as well as in butcher's shops and it's important for the risk in public health. This is the first time, in the Tolima region that the Salmonella prevalence is known in slaughterhouses and butcher's shops.
