Introduction: Indiscriminate use of antibiotics is a common practice in our community to restore cattle to health without considering the impact of this action on animal health or on the products that cattle can provide to humans. Objective: To determine the presence of antibiotic residues in raw milk sold in the “10 de Agosto” market in Cuenca City, Azuay province. Methodology: The study was a qualitative, experimental, cross-sectional study. The universe consisted of 5 raw milk stalls, from which 90 samples were obtained. AMINO 3IN1 and 3IN1 BST were used for the determination of antibiotics. Results: In 18 out of the 90 samples analyzed (20%), antibiotic residues were found; the most frequent antibiotic was sulfonamide (18.88%) and gentamicin (1.11%). Conclusion: Antibiotic residues were found in the raw milk samples; sulfonamide was the most frequent. The highest amount of antibiotic traces was in stall 5. In stall 2, gentamicin was observed (5.56%), while no antibiotic residues were found in stalls 3 and 4.
