Background and Objectives: Currently there is a growing concern about the sanitary conditions of food products made available to population, as there is a wide range of pathogens associated with food contamination. The purpose of this study was to isolation and susceptibility profile analysis of Escherichia coli, Salmonella spp. and Staphylococcus positive coagulase from ground beef samples collected in commerce of Pelotas city, Rio Grande do Sul, Brazil. Methods: For bacterial isolation were utilized 20 samples of ground beef originating in local commerce, being performed the research for E. coli, Salmonella spp. and S. coagulase positive. Any bacterial strains isolated were submitted to analysis of the susceptibility profile, where ten different antibiotics have been tested. Results: The susceptibility profile ranging among isolates in Salmonella spp., we observed the higher rate multidrug resistance, 58% of these were resistant to multiple antibiotics. In isolates of Escherichia coli occurred 44.4% of multidrug resistance. Strains of Staphylococcus positive coagulase showed the lowest rate, 25% of these have been multiresistant, and all isolates were sensitive to oxacillin. Conclusions: The high contamination of samples of ground beef highlights the need for a good hygiene practices and transport animal products. Resistance and multiresistance levels to the antibiotics tested, may demonstrate a possible inappropriate use of antimicrobials in veterinary medicine.
