Poultry meat has been identified as one of the principal foodborne source of Salmonella. In this preliminary study the prevalence of Salmonella spp. contamination of broiler carcasses, were determined. Sixty samples were collected from poultry carcasses from the commercial broiler slaughtering facility in Namakkal, Tamil Nadu. The presence of Salmonella spp in collected samples was assessed by performing the pre-enrichment and enrichment culture, followed by PCR assay. The primers were selected from the invA gene specific for the detection of Salmonella spp. In this study 8.3% of poultry carcasses were found to be contaminated with Salmonella spp. In order to provide a more accurate profile of the prevalence of Salmonella spp in broiler carcasses, it is pertinent to use inv A gene specific PCR method that could be considered as an appropriate alternative to conventional culture method.
