An evaluation of the presence of Salmonella spp. in broilers of the naked neck Label Rouge lineage

Abstract

Paulo Coutinho Ambrosio

The presence of Salmonella serovars in poultry products is a worldwide public health concern. Moreover, salmonellosis is one of the most common foodborne diseases with approximately 10 million cases of human infection occurring per year worldwide. The aim of this study was to assess the presence of Salmonella spp. in broilers of the naked neck Label Rouge lineage by cloaca swab technique in a broiler house in the northwestern region of the state of Paraná, Brazil. Cloaca swab samples were collected from 100 broilers raised under the free-range farming system and the detection of Salmonella spp. was carried out using biochemical and serologic techniques. No Salmonella spp. was detected on the poultry studied. This result may indicate the free-range farming system as a contributing factor to reduce the presence of foodborne pathogens in poultry production as compared to confinement and intensive farming system. More studies in this area are necessary in order to understand the real benefits of the free-range farming system in relation to foodborne pathogens.
