ABSTRACT: An investigation was made to survey the possible presence of Staphylococcus aureus, Escherichia coli and Salmonella spp. from fast-food shops in Al-Ahsa Province, Kingdom of Saudi Arabia (KSA), as potential reservoir of human infection and antimicrobial resistance. A total of 100 samples of shawarma poultry meat were collected from different localities of the province. Conventional, commercial VITEK 2 and molecular techniques were used for isolates’ identification and antibiogram detection. Staph aureus was isolated at a rate of 14% and CNS as Staph. sciuri and Staph. xylosus at 2%. E. coli was identified at a rate of 12% and antibiogram analysis showed 41.67% of isolates to be extended-spectrum β-lactamases (ESBL) with evidence of multi-drug resistance (MDR). Molecular analysis of E. coli revealed presence of sero-groups O1 and O2, entero-toxigenic (ETEC), shiga-toxigenic, ST540 and the prototypical ETEC strain H10407 which are potential public health hazard. Salmonella enterica serovar Enteritidis showed 19% prevalence while S. Typhimurium with 8% prevalence. Anti-microbial sensitivity of 15 strains of S. Enteritidis and 5 strains of S. Typhimurium showed multi-drug resistance (MDR).
