abstract={<i>Escherichia coli</i> O157:H7 is one of the most dangerous zoonotic pathogens of meat. The present investigation was done to study the prevalence and antibiotic resistance of <i>E. coli</i> O157:H7 strains isolated from raw meat samples. A total of 458 meat samples were collected. Samples were cultured using what? After which sorbitol negative isolates were analyzed for <i>rfbO157</i> and <i>flicH7</i> genes. Thirty-six out of 458 meat samples were positive for sorbitol negative strains of <i>E. coli</i> (7.86%). All of the sorbitol negative strains were also positive for <i>rfbO157</i> and <i>flicH7</i> genes. Prevalence of <i>E. coli</i> O157:H7 strains were 7.86%. The prevalence of <i>E. coli</i> O157:H7 in chicken meat was higher than the other samples (16.25%). The genes that encode resistance to ampicillin (<i>CITM</i>) (100%), gentamicin (<i>aac(3)-IV</i>) (94.44%) and tetracycline (<i>tetA</i>) (61.11%) had the highest prevalence. <i>Escherichia coli</i> O157:H7 strains from raw meat samples from ruminants and poultry had the highest resistance to ampicillin (100%), tetracycline (83.33%) and gentamicin (83.33%) respectively. Strains of antibiotic resistant <i>E. coli</i> 0157:H7 found in this present study are of public health importance.},
