Sažetak
The objective of this study was to determine the oxytetracycline residues in cow’s milk collected in farms of Tetovo in Macedonia. The cow’s milk samples produced in this area are controlled applying qualitative analytical tests for oxitetracycline residues in 262 milk samples through specific ELISA test. After this control positive milk samples were kept in freezing conditions to be analyzed by high performance liquid chromatography (HPLC) method in order to perform qualitative evaluation of oxytetracycline. The quantitative control with ELISA confirmed that 5.3% (14/262) of milk samples were positive for oxytetracycline residues. From analytical check performed by HPLC was confirmed that 2.3% (6/262) of total milk samples had different values oxitetercycline residues. Referring to MRL for oxitetracycline in milk only 1.6% (4/262) of analyzed samples has been confirmed with values higher than this limit. The quantity values of oxitetracycline calculated after analytical check with HPLC in 1 liter milk ranged 65ug/l to 1300ug/l (ppb). These study results are showing cases of oxitetracycline residues with high doses of oxytetracycline in milk samples signalizing for risk of public health in consumers in Tetovo and other regions of Macedonia.
