-- Salmonella spp., is one of the most important causes of gastroenteritis in humans worldwide, constituting a public health problem. The slaughtering process favors the spread of microorganisms and may increase the frequency of Salmonella in the final product. The possible sources of contamination are the wash water of the carcasses, the rupture of the viscera during evisceration and the poor hygiene of the establishment. In this study we sought to determine the presence of Salmonella. For this purpose 170 samples of the body surface of carcasses (among eviscerated and non eviscerated) and 170 cloacal swabs were analyzed. These samples were acquired from 17 slaughterhouses in Metropolitan Lima. For the body surface, we used the method of rinsing described by USDA / FSIS (2008). We used the traditional method for the isolation of Salmonella. In slaughterhouses where the evisceration was not carried out the percentage of samples of body surface carcasses tested positive for Salmonella spp., was 21.3%; and 28.8% for cloacal swabs. While in slaughterhouses where the evisceration was carried out, 25.6% of body surface samples were contaminated and 35.6% of the cloacal swabs were positive. The degree of concordance of the results for both sampling methods was insignificant (k = 0.074, k = 0.146). In conclusion the results of this study show that Salmonella spp. is present in the slaughterhouses of Metropolitan Lima. -- Keywords: Salmonella, chicken carcasses, cloacal swabs, body surface, slaughterhouse
