One of the major consequences of the misuse of veterinary drugs in livestock farming is the emergence of strains resistant to the antibiotics used. E. coli is very often involved in cases of poisoning. This study aimed to determine the level of circulation of multidrug-resistant Escherichia coli associated with meat consumption in Côte d'Ivoire. Microbiological analysis of 150 beef samples (50 from slaughterhouses, 50 from markets, and 50 from braised meat) enabled us to isolate 181 strains of Escherichia coli. These strains were phenotypically and molecularly characterized respectively for their multidrug resistance capability and for the possibility of possessing antibiotic resistance genes: blaSHV, blaIMP, and blaTEM. As results, the E. coli contamination rate was 16% for braised meat and 22% for fresh meat from slaughterhouses and markets. The average load of E. coli in the matrices ranged from 2.2 ± 0.05 to 5.8 ± 0.1 logCFU/g. The prevalence of E. coli was 60.2%, 33.7%, and 06.1% for samples from markets, slaughterhouses, and braised meat, respectively. Of 41 multidrug-resistant E. coli, 29.3% and 17.1% were resistant to the blaSHV and blaIMP resistance genes, respectively. The emergence of antibiotic resistance highlights the need for training in the better use of veterinary drugs.
