Isolation and Characterization of Methicillin-Resistant Staphylococcus aureus Strains from Louisiana Retail Meats

Abstract

We investigated the prevalence of Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) in 120 retail meat samples from 30 grocery stores in Baton Rouge, LA. S. aureus strains were recovered from 45.6% of pork samples and 20% of beef samples, whereas MRSA strains were isolated from six meat samples (five pork samples and one beef sample). The MRSA isolates were of two strain types (clones), one harboring Panton-Valentine leucocidin and belonging to pulsed-field gel electrophoresis type USA300 and the other one belonging to USA100.

Empfehlungen zur Prävention und Kontrolle von Methicillin-resistenten Staphylococcus aureus-Stämmen (MRSA) in medizinischen und pflegerischen Einrichtungen

“…MRSA wurde auch in Lebensmitteln in den Niederlanden, den USA und Kanada nachgewiesen [234][235][236]. Diese Nachweise erfolgten alle aus einer Anreicherungskultur heraus.…”

Isolation of Methicillin-Resistant Staphylococcus aureus Strains Producing Enterotoxins A, K and Q From Chicken Meat in Isfahan, Iran, 2014

“…The isolation of MRSA from different meat samples was reported previously from different countries (16)(17)(18)(19)(20)(21)(22)(23). Another study (10) reported MRSA strains from poultries in Iran; therefore, the isolation of MRSA strains from chicken meat was not surprising.…”

Methicillin-Resistant Staphylococcus aureus (MRSA) in Food- Producing and Companion Animals and Food Products

“…In 2010, the Federal Institute for Risk Assessment reported a contamination rate of 32% in turkey meat in Berlin, Germany [126]. Similar contamination frequencies were reported from Canada and the USA [72,127], as well as from Taiwan [128]. Moon et al [91] reported that the S. aureus isolated from chicken carcasses contained 1.3% MRSA, which was more than the MRSA isolated from other animal carcasses (0.3%) in Korea.…”

“…A USA survey of 120 retail meat samples indicated that 39.2% contained S. aureus strains, 5% of which were MRSA of the types USA100 (ST5) and USA300 (ST8) [127]. A Canadian survey [72] found that 7.7% of retail meat samples harbored MRSA; 30% belonged to the clonal complex CC398, 40% were CC8, and 30% were CC5, a strain commonly found in humans in both the USA and Canada.…”
