Abstract The increased demand to produce large quantities of meat and animal products for human consumption has promoted the indiscriminate use of antimicrobials. The increased use of these substances in the production of poultry, has negative consequences on Public Health due to the fact that the accumulation of antimicrobial residues in the organs and tissues of poultry might reach the consumer. The presence of antimicrobial residues can cause problems of hypersensitivity in humans, or the emergence of antimicrobial resistant pathogens. The purpose of this work was to assess the presence of antimicrobial residues in kidney and muscle tissue of poultry, commercialized in four municipalities of the Metropolitan Area of Guadalajara, Jalisco. The results show that kidney samples had a higher number of positive results compared to muscle tissue. Inhibitors of the folate pathway (sulfamethazine) were the antimicrobials with the highest number of positive results in kidney samples. In contrast, in muscle tissue, β-Lactam (penicillin) were the antimicrobials with the highest number of positive samples. Regarding the analysis of the results by municipalities, it was observed that one of them showed a greater number of positive samples for all the classes of antimicrobials evaluated. This work shows the presence of antimicrobial residues in kidney and muscle tissues of poultry, commercialized in retail sites. Therefore, it is necessary to increase efforts to monitor and control the use of antimicrobial in poultry farms.
