The aim of this study was to analyse the susceptibility of Enterobacteriaceae strains isolated from food to antibiotics used in human therapy. The tests were conducted on 433 samples of raw and processed meat intended for sale. A total of 114 strains belonging to Enterobacteriaceae were isolated by the classical bacteriological technique. Escherichia, Klebsiella, Serratia, Enterobacter, Proteus, Hafnia, Citrobacter, Salmonella and Shigella were cultured from samples of beef, pork, poultry and ready-made meat products. Antibiotic susceptibility was tested by the mean of E-tests for the following antibiotics: piperacillin, piperacillin with tazobactam, cefotaxime, cefuroxime, imipenem, ceftazidime, gentamycin, tobramycin, ciprofloxacin and trimethoprim with sulfamethoxazole. Over 37% of the strains isolated were resistant to some of these antibiotics, and 34% showed resistance to at least 2 of them. Resistance was observed most frequently to cephalosporins, penicillins and trimethoprim with sulfamethoxazole, which may suggest that these antibiotics are used excessively in veterinary medicine.
