Detection of “Salmonella” spp. in broiler buildings and stuff of slaughterhouse in the central region of Mato Grosso do Sul Ocorrência de "Salmonella" spp. em aviários e abatedouro de frangos de corte na regi o central de Mato Grosso do Sul

The aim of this study was to search Salmonella spp. occurrence in broiler poultry shed and poultry products from slaughterhouse in central county of Mato Grosso do Sul. Were analyzed 134 drag swabs in broiler poultry farms located in five counties 123 samples of chickens carcasses, viscera and chilled water from the slaughterhouse. The results showed that 11.28% of 257 samples tested positive for Salmonella, and 1.95% from the field and 9.33% from the slaughterhouse. The serovars found were Salmonella Enteritidis (1.16%), S. Typhimurium (1.94%), S. Senftenberg (0.77%), S. Schwarzengrund (4.28%), S. Livingstone (0.38%), S. Corvallis (1.55%) and Salmonella enterica subspecies enterica (O: 4.5:-:1.2) with 1.16%. The use of two enrichment broths and two or more plating means increases the chances of Salmonella spp. Isolation. The serovars Enteritidis and Typhimurium, important in the poultry industry, were found in field and slaughterhouse. It can be concluded that there is an occurrence of different serovars of Salmonella spp. In poultry slaughterhouse and in Mato Grosso do Sul central county. Serovar Schwarzengrum shows the highest percentage of occurrence in the slaughterhouse, suggesting that further studies are conducted to determine the importance of presence compared to other serovars. Control programs and risk analysis are essential for maintaining the health of poultry and reduce potential health risks to the consumer. Objetivou-se com este estudo pesquisar a ocorrência de Salmonella spp. em aviários de frangos de corte e em produtos de abatedouro avícola na regi o central de Mato Grosso do Sul. Foram analisados 134 suabes de arraste em aviários de frangos de corte localizados em cinco municípios e 123 amostras de carca as de frango, vísceras e água do chiller provenientes do abatedouro. Os resultados demonstraram que 11,28% das 257 amostras apresentaram resultados positivos para Salmonella, dos quais 1,95% provenientes do campo e 9,33% do abatedouro. Os sorovares encontrados foram: S. Enteritidis (1,16%), S. Typhimurium (1,94%), S. Senftenberg (0,77%), S. Schwarzengrund (4,28%), S. Livingstone (0,38%), S. Corvallis (1,55%) e Salmonella enterica subspécie enterica (O:4,5:-:1,2) com 1,16%. A utiliza o de dois caldos de enriquecimento e de dois ou mais meios de plaqueamento aumenta as chances de isolamento de Salmonella spp. Os sorovares Enteriditis e Typhimurium, importantes na indústria avícola, foram encontrados no campo e no abatedouro. Pode-se concluir que há ocorrência de diferentes sorovares de Salmonella spp. nos aviários e no abatedouro da
