Introduction:Staphylococcal food poisoning is one of the most common food-borne diseases. The antibiotic resistance of Staphylococcus aureus has been reported globally. Today, strains of Staphylococcus aureus in food have become a problem in clinical infections and are considerde as a serious public health concern.
Methods: A total of 100 samples were tested in the laboratory; including 75 handmade and 25 industrial hamburger samples. The Staphylococcus aureus samples were isolated and identified according to the National Iranian Standard No. 6806-3. Antibiotic resistance was determined by disk diffusion method and minimum inhibitory concentration was performed. In this study, the antibiotics penicillin, ciprofloxacin, erythromycin, clindamycin, chloramphenicol, cefoxitin, trimethoprim-sulfamethoxazole, tetracycline, gentamicin, vancomycin, and oxacillin were used.
Results: Of 100 analyzed hamburger samples, 39 samples were infected with Staphylococcus aureus (23 industrial and 16 ­ handmade samples). All isolates of Staphylococcus aureus (100%) were susceptible to gentamicin and vancomycin antibiotics.
Conclusions: Due to the importance of Staphylococcus aureus, as the supergene antigen and its role in causing food poisoning, contamination of foodstuffs with Staphylococcus aureus can threaten the consumers' health.
