Prevalence of methicillin-resistant Staphylococcus aureus in meat.

摘要: Recently the isolation of methicillin-resistant Staphylococcus aureus (MRSA) strains from several food-producing animals has been reported. During slaughtering MRSA-positive animals, contamination carcasses with MRSA may occur and consequently meat these get contaminated. The aim this study was to estimate prevalence in raw samples retail trade. Samples beef, pork, veal, lamb/mutton, chicken, turkey, fowl game were collected A detection method including a two-step enrichment Mueller-Hinton broth+6.5% NaCl phenol red mannitol broth containing ceftizoxime aztreonam, followed by on ID agar (bioMerieux) evaluated subsequently applied for meats. isolated 264 (11.9%) 2217 analyzed. Isolation percentages species were: beef (10.6%), veal (15.2%), lamb mutton (6.2%), pork (10.7%), chicken (16.0%), turkey (35.3%), (3.4%) (2.2%). majority (85%) belonged spa-types pulsed-field gel electrophoresis (PFGE) non-typeable (NT)-MRSA, corresponding multilocus sequence type ST398, also recently Netherlands pigs. However, smaller part found be other ST's, possibly human origin. Further studies are needed elucidate transmission routes relation foods provide tools preventing spread MRSA. At present high not shown contribute significantly dissemination humans possible health hazard consumers presence should further elucidated.
