RESUMO

The aim of this work was identify the risk factors for S. Enteritidis in the production system of broiler chickens, to evaluate, qualify and quantify the variables studied and to make a theoretical model of risk assessment of this serovar in broilers in integration system. Therefore, the data was obtain from works of some authors and supported the proposed model of microbiological risk analysis. For molecular characterization were included 42 Salmonella spp. strains isolated from chicks and feed experimentally inoculated with S. Tiphimurium. After inoculation of feed with the specific dose of strain, it was submitted to treatment with propilic, formic and acetic acids in several concentrations and it was given to birds ad libitum until 21 days old, when they were sacrificed. It was obtained different patterns through the ERIC and BOX-PCR techniques, which showed good discrimination power for the strains analyzed.
