- Resistant and enterotoxigenic Staphylococcus aureus are considered to be one of the major causes of foodborne diseases. The present investigation was done to study the pattern of antibiotic resistance and enterotoxigenic genes profile among the S. aureus strains isolated from traditional sweets. Two‐hundred sweet samples were cultured and S. aureus strains were identified. Antibiotic resistance and enterotoxigenic gene profile were studied using disk diffusion and polymerase chain reaction (PCR), respectively. Seventy‐nine out of 200 (39.50%) traditional sweet samples harbored S. aureus. Baghlava (79.16%) and Ghotab (73.10%) had the highest prevalence of S. aureus. S. aureus strains harbored the highest prevalence of resistance against penicillin (87.34%), tetracycline (84.81%), and erythromycin (65.82%). Distribution of sea, seb, sec, and sed were 5.06, 1.26, 8.86, and 1.26%, respectively. Presence of resistant and enterotoxigenic S. aureus showed an important public health issue. However, further researches are required to found additional epidemiological aspects of the bacteria. PRACTICAL APPLICATIONS: Due to the high‐consumption rate of traditional sweet, they should have a high microbial quality. Staphylococcus aureus is common foodborne bacteria with an emergence of antibiotic resistance and enterotoxin production. This study emphasizes the importance of multidrug resistant enterotoxigenic Staphylococcus aureus in traditional sweet samples. Results represented that traditional sweet samples may act as a reservoir of S. aureus with ability to transfer antibiotic resistance and enterotoxin genes to human population.
