Abstract:
Food with animal origins and especially meat may play an important role in
transmission of methicillin-resistant strains of Staphylococcus aureus to humans. The present
investigation was carried out to determine the prevalence of MRSA in various types of Iranian
meat samples as well as study their antimicrobial resistance properties. Nine-hundred raw
meat samples were collected during various months of the year. Samples were cultured and
those that were MRSA-positive were subjected to the disk diffusion method to study the
antibiotic resistance pattern. One-hundred and sixty out of 900 raw meat samples (17.7%)
were positive for MRSA. Raw sheep meat samples had the highest (24.0%), while raw camel
meat samples had the lowest (10%) prevalence of MRSA. Samples which were collected in
June, July, August, September and June months had the highest prevalence of MRSA. Bacterial
strains were also resistant to ampicillin (100%), penicillin G (100%), gatifloxacin (96.8%),
ceftriaxone (80%) and oxacillin (76.2%) antibiotics. We found that only one isolate was resistant
to all tested antimicrobial agents. Contaminated meat samples are potential risk factor for
transmission of MRSA. Thoughtful antibiotics prescription, control the hygienic quality of
meat inspections and increase the hygienic status of butchers and slaughterhouses can
decrease the prevalence of MRSA in meat.
