Estimated dietary exposure to veterinary residues in chicken and eggs

Background: Chicken tissues and eggs were analyzed for residues of eight veterinary drugs including albendazole, piperazine, tiamulin, chloramphenicol, levamisole, sulphathiazole, sulphamethoxazole and oxytetracyclineoxytetracycline. Results: Mean residue concentrations of all drugs varied by tissue and ranged from 0.004 μg/kg for tiamulin in eggs to 8.6 μg/kg for chloramphenicol in liver. Total residues of all drugs in the liver generally exceeded that of the kidney, muscles and eggs by at...
