• The goal of this study was to investigate the prevalence of extended-spectrum β-lactamase production in Enterobacterales isolated from retail sheep meat in Zagazig, Egypt. One hundred random samples of sheep meat were collected from different retail butcher shops (n = 5) in the city of Zagazig, Egypt. Bacterial isolates were identified by MALDI-TOF MS and screened for antibiotic susceptibility by disk diffusion; further genotypic characterization of β-lactamase-encoding genes was performed with Real-Time PCR. E. coli strains were phylotyped with the Clermont triplex PCR method. Of the total of 101 bacterial isolates recovered from retail sheep meat samples, 93 were E. coli, six were Enterobacter cloacae and two were Proteus mirabilis. As many as 17% of these 100 samples showed ESBL phenotypes, all were E. coli. The bla genes were detected in seven isolates (six were bla and one was bla ), three isolates harboured bla (all were bla ), and two carried genes of the bla family (both were bla ). Eight E. coli isolates expressed ESBL phenotype but no bla , bla or bla genes were detected by PCR. ESBL- positive E. coli isolates were nearly equally distributed over the commensal groups A/B1 and the virulent group D. Nearly one in five sheep meat samples was contaminated with ESBL-E. coli. This further corroborates the potential role played by contaminated meat in the increasing resistance rates that have been reported worldwide.
