Residues of antibiotics in food of animal origin may pose health hazards to consumers. For this reason, their presence must be systematically controlled. One aspect of the official control is a national programme for the control of banned substances and of chemical, biological and medical product residues in animals and in food of animal origin, developed and implemented in accordance with Council Directive 96/23/EC. The aim of this study was to present the results of investigations of antibiotic residues carried out as part of this programme in 2005-2010. Samples were taken by veterinary inspectors. Analyses of antibacterial substances were performed using microbiological screening methods (4-plate method and Delvotest SP-NT). Positive results were confirmed by the chromatography technique. Furthermore, some of the selected antibiotics were detected by instrumental methods. During the period under analysis, the residues of antibacterial substances were detected in 0.32% of samples tested. The residues of sulphonamides were identified in 25 samples of honey, whereas tetracyclines in two samples of poultry. No residues of quinolones, streptomycin, penicillins and florfenicol were detected. The presence of banned substances was detected in 9 samples: nitrofurans in 2 samples, and chloramphenicol in 7.
