The objective of this study was to analyze the antibacterial resistance of E. coli isolated from ground beef marketed in Bom Jesus - PI. Isolation was performed following the multiple-tube technique. Inoculum obtained from the positive tubes was inoculated into plates containing EMB agar to observe the characteristics of the colonies. After confirmation, the colonies were submitted to antimicrobial susceptibility test. E. coli strains grew in 26 samples (43.33%). Of these, 15.39% (4/26) of the strains were sensitive to all antimicrobials tested, while 22 (84.61%) showed some resistance. The results showed that ground beef has the potential to carry E. coli resistant to the main antimicrobials used in infection therapy.
