Abstract EN
Milk and dairy foods have frequently been implicated in staphylococcal food poisoning, and contaminated raw milk is often involved.
The aim of the study was to determine the occurrence of methicillin-resistant Staphylococcus aureus (MRSA) in raw cow milk cheese produced in Mexico.
A total of 78 unpasteurized cow milk cheese samples were screened for S.
aureus.
The isolates were identified as S.
aureus based on morphology, Gram stain, catalase test, coagulase test, and mannitol salt agar fermentation.
Isolates were subjected to biotyping, the methicillin resistance was analyzed using the disk diffusion, and the Staphylococcus enterotoxin A (SEA) production was examined by a dot-blot analysis.
From a total of 78 samples of unpasteurized cheeses analyzed in this study, 44 cheeses were positive for S.
aureus; however, a differential contamination between the different types of cheeses was observed, with high risk of contamination in adobero cheese (12, 95% CI 1.75 to 94.20; p=0.002).
In this study, the frequency of methicillin-resistant Staphylococcus aureus (MRSA) was 18.1% (8/44) and of enterotoxin A producers was 18.1% (8/44).
When classified by biotypes, MRSA only belongs to the human ecovar biotype (2/8, 25%) and the D biotype (4/8, 50%).
S.
aureus producers of enterotoxin A were distributed in specific nonhost biotypes.
