Prevalence and Antibiogram Assessment of<i> Staphylococcus aureus</i> in Beef at Municipal Abattoir and Butcher Shops in Addis Ababa, Ethiopia

Abstract

The prevalence of <i>S. aureus</i> in the abattoir, butcher, cutting table, hook, and knife was 9.4%, 19.8%, 15%, 15%, and 22.5%, respectively. The prevalence of <i>S. aureus</i> in the knife and butcher was found to be 2.8 (OR = 2.8, CI = 1.2-6.4) and 2.4 (OR = 2.4, CI = 1.6-3.6) times that of the abattoir results (<i>p</i> < 0.01). The antimicrobial susceptibility testing was also conducted on 133 isolates of <i>S. aureus</i> using the disc diffusion susceptibility method. Bacitracin, neomycin, and methicillin were found to be 100% resistant to <i>S. aureus</i>. To avoid the presence of pathogenic <i>Staphylococcus</i> isolates, preventive measures using good hygienic practices during slaughtering and handling of the beef carcasses are recommended.
