Salmonella has been considered the major cause of foodborne diseases in the world. In this study, we evaluated the phenotypic resistance antimicrobial of 133 isolates of Salmonella, collected from different types of foods, in Minas Gerais - Brazil, from 2001 to 2021. The antibiogram results showed that 82.7 % of Salmonella isolates were resistant to at least one of the 16 antimicrobials tested, with highlight to resistance tonalidixic acid (51.9 %), nitrofurantoin (46.6 %), streptomycin(13.5 %), ampicillin (13.5 %) and tetracycline (12.8%). There were differences in antimicrobial resistance among Salmonella serotypes. S. Typhimurium showed resistance to a greater number of therapeutic agents (15 of 16 antimicrobial tested) and S. Enteritidis a high rate of resistance to nitrofurantoin (89.5 %), nalidixic acid (77.0 %) and ciprofloxacin (54.1 %). Thirty isolates of Salmonella (22.5%) were classified as multidrug resistant due the resistance to at least one antimicrobial from three different classes.Salmonella isolated from animal products showed significant resistance ampicillin, chloramphenicol, gentamicin, streptomycin, sulfamethoxazole-trimethoprim and tetracycline, when compared to Salmonella collected from other foods. The results this study reinforced the need to implement an integrated surveillance system to monitor the antimicrobial resistance in Salmonella in the country.
