The Prevalence of Salmonella spp. In Bovine Carcass at Tabriz Slaughterhouse, Iran

Foods of animal origin are considered to be the major sources of food borne salmonellosis. Salmonella cause much of the food poisoning in the world. Salmonella live in the intestinal tracts of humans and other animals. Humans are usually infected by eating foods contaminated with animal feces. For this study, 75 cattle carcasses were randomly sampled from Tabriz commercial slaughterhouse from September 2007 to January 2008. Sample swabbing of the carcasses was performed after evisceration. A surface of about 100 cm2 per site was swabbed using two swabs for interior and the exterior surfaces of cattle carcass. Swabs were transported to the microbiological laboratoiy of Islamic Azad University, Shabestar branch and, for the isolation of salmonella from the sample was used culture media, supported by biochemical tests. Of all samples salmonella was not found.
