Prevalence of Livestock-Associated Methicillin-Resistant Staphylococcus Aureus (LA-MRSA) Among Farm and Slaughterhouse Workers in Italy



Prevalence of Livestock-Associated Methicillin-Resistant Staphylococcus Aureus (LA-MRSA) Among Farm and Slaughterhouse Workers in Italy



Journal of Occupational and Environmental Medicine 60(8): E416



We measured the prevalence of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) in swine livestock workers, examined LA-MRSA resistance profile, and associated carriage with the working activities. Information was collected on demographics and occupational history. Swabs were collected and tested for the isolation of S. aureus, examined for antimicrobial susceptibility, and all MRSA underwent ST398qPCR assay. LA-MRSA was isolated in 7.3% of the 396 enrolled workers. LA-MRSA colonization was more likely in farmers than in slaughterhouse workers (Fisher exact P = 0.001). Carriage was associated with herd size, being less frequent in small/medium farms (odds ratio = 0.20; 95% confidence interval = 0.07 to 0.53), and with the number of working days per week (OR = 2.11; 95% confidence interval = 1.07 to 4.19). LA-MRSA carriage is strongly animal-exposure related, and educational intervention informing about the risks related to the activity with livestock is needed.
