Background and Objective: Paying attention to antibiotic residues in milk is important due to its health effects on the occurrence of microbial resistance in consumers, as well as its harmful effects on the dairy industry. This study was carried out with the aim of determining the amount of oxytetracycline, enrofloxacin, and penicillin G in raw milk samples produced in Fars province, which were detected as contaminated during screening with a rapid kit.
Materials and Methods: The samples were first examined with a rapid commercial kit for the presence of antibiotic residues. Then the amount of oxytetracycline, enrofloxacin and penicillin G antibiotics in the positive samples belonging to the middle month of each season was determined using the liquid chromatography-tandem mass spectrometry method.
Results: Antibiotic residues were found in 121 (7.7%) samples by the commercial Eclipse kit. Both season (p<0.001) and region (p<0.01) of sampling had a significant effect on antibiotic residues in raw milk. In the chromatographic method, antibiotic residues of oxytetracycline and enrofloxacin were detected in 6 (27.3%) samples, none of which exceeded the permissible limit determined by the Iranian Veterinary Organization.
Conclusion: Although the amount of antibiotics detected from raw milk from Fars province was much lower than the permissible limit, it is necessary to implement further executive, educational, and research measures to minimize these residues in raw milk due to the possibility of the presence of other antimicrobial substances.
