“…The results in table (1) declared that the examined Kareish cheese samples were the most contaminated with Staphylococci, followed by White cheese, Roomy cheese, and Flamingo cheese. While referring to machine and hand swabs, hands revealed higher contamination with Staphylococci, which also appeared as high incidence of machine contamination that indicated low hygienic practices.…”

A Hundred-eighty random cheese samples includes varieties of cheese, soft (kareish and white), hard (Roomy), processed (Flamingo), beside machine and hand swabs were collected from different supermarkets (30 of each), at Qalubiya Governorate, Egypt to investigate the incidence of Staphylococci with especial reference to methicillin-resistant Staphylococcus aureus (MRSA) strains. The results revealed that the mean values of staphylococci and Staph. aureus counts (cfu/g) in kareish cheese samples were 3.16×10 5 and 6.57×10 4 , respectively. For white cheese samples, they were 7.60×10 4 and 5.12×10 4 , respectively. For Roomy cheese, samples were 5.79×10 4 and 3.38×10 4 , respectively. For Flamingo cheese samples were 2.96×10 4 and 1.05×10 4 , respectively. For machine swab samples were 1.02×10 4 and 1.48×10 3 , respectively. For hand swab samples were 1.43×10 4 and 3.71×10 3 (cfu/ml), respectively. A total of 118/180 (65.5%) isolates of staphylococci species, includes 55 S. aureus (30.6%). All 55 isolated Staph aureus strains were coagulase positive while, other isolated staphylococcal strains (63) were coagulase negative. The isolated Staph. aureus was highly resistant for methicillin followed by oxacillin, nalidixic acid, ampicillin, oxytetracycline, cefotaxime and streptomycin. Meanwhile, it was highly sensitive to vancomycin followed by norfloxacin, gentamicin, meropenem and ciprofloxacin. A 49 out of 55 Staph. aureus strains grew well on ORSAB media (they were MRSA strains). Finally, Staph. aureus and MRSA strains were found in the examined cheese samples sold in markets at Qalubuiya Governorate; beside that MRSA strains were detected that threats the consumer's health.
