Veterinary drug residues could affect meat quality and safety. This study
was undertaken to detect chloramphenicol ( CAP) residues in 45-age chickens that
husbandary -sacrificed at 1.5, 2.5, and 3.5 hr after CAP-individual injection dosage of
20 mg/kg . The obtained recovery was found to be 75.78 %. The detected CAP-
residue was higher than the allowed MRLs for CAP-drug and Zero tolerance level.
CAP·residue was acceptable at time of chicken consumption, hence most samples of
chicken parts; Liver, Kidney and Internal intestines were completely CAP-depletion at
2.5 hr and 3.5 hr sacrificing. CAP-residue in muscle tissues showed higher amounts
than that of MRLs at the end of the experiment which was 0.0308 ppm. So, muscle
tissue was considered to be target tissue of residue analysis and long withdrawal
period was required.
