Presence of Tetracycline-Group of Antibiotics in the EggsCoded According to the Cultivation Method

In the present study, the presence and levels of tetracycline-group antibiotics in the eggs codedaccording to the cultivation method (0-3) and those not coded were investigated. For this purpose,total 60 eggs (30 in each group) were used as sample. ELISA method and commercial test kitswere used in the analyses. According to the results of the analysis , tetracycline residuals werefound in 66.7% (n=40) of the egg samples. The level of tetracycline ranged between 2.40–83.74ppb (mean: 37.59±25.11) in all the eggs samples. Only 33.3% (n=20) were found to contain notetracycline residual. No tetracycline residue was detected in any of the organic egg samples.Tetracycline residue levels determined in egg samples were found to comply with the legal limitsstated in the European Union Commission and Turkish Food Codex Egg Communiqué.
