Salmonella spp. are widely distributed in nature, which the main reservoir of the bacteria are humans, domestic and wild animals’ gastrointestinal tract. Humans infection is usually by food poisoning and poultry, beef and pork are often sourcing of contamination. Considering the Brazilian great representativeness in the global market, a national exploratory study to estimate Salmonella spp. prevalence in abattoirs under federal inspection service has great importance. Risk assessment by quantifying and characterizing the bacteria presence, through the abattoir’s size classification and commercialization license, has a positive impact on risk mitigation actions, whether they are token by government, companies or both. These efforts improve all the production chain, resulting in international market confidence in Brazilian`s meat, new marketing agreements and economy improving. This study aimed to contemplate a brief contextualization of Brazilian poultry and pork meat market and international trading; present the results of the exploratory study of the prevalence of Salmonella in pig carcasses, which was 10% (95% CI 7.5-43.2) before chilling and 4.6% (95% CI 3.1-6.6 ) after chilling, and Salmonella in poultry carcasses which was 17.88% (95% CI 14.34-22.05), also the sanitary risk assessments respectively. In final considerations relate implemented actions due to study and suggest improvements regarding Salmonella prevention, especially at slaughter sites.
