Antimicrobial Resistance of Escherichia coli Isolated from a Variety of Meats in Sabo Market, Ikorodu, Lagos, Nigeria.

Abstract

Foodborne pathogens such as E. coli can be found in large quantities in animal meat. This study was carried out in Sabo Market Ikorodu, Lagos, Nigeria, to determine the prevalence and antimicrobial resistance of Escherichia coli isolated from meats. The procedure for isolating Escherichia coli was based on the USA-FDA Bacteriological Analytical Manual. The Kirby-Bauer disk diffusion method was used to determine antibiotic resistance patterns in Escherichia coli isolates against eight antibiotics. In the meat samples, the overall prevalence of Escherichia coli was 82.00% (169/200). Escherichia coli was found in sheep meat (87.50%), Guinea fowl (87.50%), cow meat (85.00%), local chicken (77.50%), and goat meat (72.50%). The average coliform count was 3.12 CFU/cm2, with guinea fowl (3.44 log CFU/cm2) having the highest count and local chicken (2.23 log CFU/cm2) having the lowest. The isolates of Escherichia coli were highly resistant to erythromycin (85.00%), tetracycline (73.33%), and ampicillin (73.33%). (71.67%). The MAR index (multiple antibiotic resistance) ranged from 0.13 to 1. Antimicrobial resistance patterns were found in 23 Escherichia coli isolates, with TeAmpE (tetracycline-ampicillin-erythromycin) being the most common. The isolates of Escherichia coli had a multidrug resistance rate of 68.33 percent. The findings revealed that Escherichia coli was commonly found in various meat types and had multidrug resistance, indicating that effective antibiotic stewardship guidelines are needed to streamline antibiotic use in the production industry.
