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.
