OCCURRENCE OF ANTIBIOTIC RESIDUES IN POULTRY FEED AND CHICKEN MEAT WITH RISK CHARACTERIZATION

Abstract

The present study was conducted to determine the occurrence of antibiotic residues in poultry feed and chicken meat with risk characterization. To perform this experiment, 5 samples of layer muscle, 5 samples of layer liver, 5 samples of broiler muscle, 5 samples of broiler liver, 7 samples of local breed chicken muscle (control) and three samples of local breed liver (control) were used. So, total 30 chicken samples and

10 feed samples (5 samples of layer feed and 5 samples of broiler feed) were collected from different poultry farm of Sirajganj and Gazipur district, Bangladesh during the period from March 2020 to June, 2021. To detect Tetracycline and Oxytetracycline residues, the collected chicken and feed samples were analyzed using High Performance Liquid Chromatography (HPLC) with fluorescence detector. In this study, 2 Layer muscle samples, 3 layer liver samples, 2 Broiler muscle samples and 2 Broiler liver samples were Tetracycline and Oxytetracycline positive whereas control muscle and liver samples were negative. Among the collected feed samples, 3 layer feed samples and 2 broiler feed samples were Tetracycline and Oxytetracycline positive but the rest of the samples showed no residue. Results showed that no chicken sample as well as no feed sample in the present study exceeded the maximum residue limit (MRL) of Tetracycline and Oxytetracycline.
