The prevalence and antibiotic resistance of Staphylococcus aureus and coagulase-negative Staphylococcus (CoNS) strains isolated from raw chicken samples (breast, neck and wing) in Ankara, Turkey, were determined. Totally, 195 Staphylococcus strains were isolated from 105 raw chicken meat samples. Of the isolates, 92 (47.2%) were identified as S. aureus and 103 (52.8%) as CoNS. Among different raw chicken samples, chicken necks showed the highest contamination incidence (39.1% for S. aureus and 38.8% for CoNS), respectively. Most of the S. aureus and CoNS isolates were resistant to one or more of the microbial agents, with none being resistant to vancomycin. However, a high percentage of S. aureus isolates were resistant to beta-lactam antibiotics such as penicillin (75%) and methicillin (50%); the CoNS tested were highly resistant to erythromycin (41.7%). The resistance to chloramphenicol was rare. The results provided evidence that raw chicken samples are frequently contaminated with S. aureus and CoNS and could be potential vehicle of resistant Staphylococcus foodborne intoxications. This calls for better control of sources of food contamination and of the spread of antimicrobial resistant organisms.
