ABSTRACT

S.aureus is generally present in the skin and nasal passages of the most human and enter into the food during production from sneezes or wound workers hands. Biofilms are one of the factors that promote adhesion and colonization, which leads to repeated or recurrent infections. Five hundred meat samples collected from different supermarkets and puncher shops. The well flat micro titer polystyrene plates and congo red agar method used to investigate the ability of the Staphylococcus aureus to form biofilms. The result of the current study found the percentage of S.aureus isolates was 30 (6%). The result of the current study presents the ability of all S.aureus isolates to form biofilm in 3 degrees, strong biofilm formation in a prevalence of 20 (66.7%), moderate biofilm formation in a prevalence 8(26.6%), and weak biofilm formation in a prevalence 2(6.7%).
