Abstract
Bacteria’s of the Staphylococcus species are major public health crisis which causes a number of human and animal diseases. A cross-sectional study was conducted from November 2017 to May 2018 to determine the prevalence of Staphylococcus aureus in Bishoftu slaughter house from carcasses and lung swab and antibiotic resistance profiles of the isolates found in the swine. In the present study a total of 150 swine were examined. From which the swab samples were obtained from carcass (n=67) and lung (n=83). Carcass was the most contaminated with S. aureus with a prevalence of 19.4% (13/67) and the prevalence from the lung swab was 15.7% (13/83). Consequently, there was no statistically significant association (P=0.547) observed between carcass and lung swabs. The prevalence of S. aureus was statistically significant difference (P=0.029) between the age of swine. Body conditions has statistically significant association (P=0.037) with the S. aureus . Swine at the age of ≤ 2 years are more susceptible to S. aureus infection. Antimicrobial susceptibility test was also conducted on 9 isolates of S. aureus , using the disc diffusion susceptibility method. In this study, varying level of resistance of S. aureus was recorded against Amoxicillin, Penicillin G, and Ampicillin, and 88.9% to Nitrofurantoin and Sulphamethoxazoletrimethoprim. Based on bacteriological culture result, and classic antimicrobial susceptibility test it is concluded that pork can be source of staphylococcus to human and routine inspections should be conducted.

Summary
Coagulase positive staphylococci (CPS) are often used as indicators for which are world wide the most important cause of Foodborne diseases (FBD). FBD are universal public health problems (Kerouanton et al, 2007; Pal, 2013) and occur commonly in developing countries, in Africa because of the prevailing poor food handling and sanitation practices, weak regulatory system, lack of financial resources to invest in safer equipment and lack of education for food handlers (Haileselassie et al, 2013) It often follows the consumption of contaminated foodstuffs especially from animal products such as meat from infected animals or carcasses contaminated with pathogenic bacteria as Salmonella species, Staphylococcus aureus, Listeria monocytogenes, Campylobacter jejiuni, and Escherichia coli O157: H7 (Nouichi and Hamdi, 2009). Staphylococcosis, an infectious bacterial zoonosis of global significance, is caused by Staphylococcus aureus, Gram-positive cocci which can be isolated, paired and most often aggregated, forming unmoving grapelike structures (Pal, 2007)
