Ninety liver samples of poultry, sheep and cattle, 30 each, were obtained from meat retail markets at Mosul city in Iraq, and were analyzed for enrofloxacin residue by using Enzyme Linked Immunosorbent Assay, ELISA [ Schen Zhen Lvshiynan Biotechnology Co., LTD. (china)].
The study revealed that the range and mean of residual enrofloxacin drug concentration in the examined liver samples of poultry, cattle and sheep were (0.01-10.69) (4.290); (0.03-3.61) (1.750); (0.02-1.32) (1.687) mg/ kg respectively. Also the study revealed that 30 (33.31%) of poultry liver samples tested positive, 8 (8.88%) of cattle samples were positive, and 5 (5.55%) of sheep samples were positive for enrofloxacin. 17 (56.66%) of the poultry samples exceeded the maximum residues limits (MRL), as did 8 (26.61%) of cattle samples, and 5(16.6%) of sheep samples. Our results have shown that the maximum mean enrofloxacin concentration was found in poultry
livers (4.290) and the minimum mean was in the ovine liver samples (1.687) while bovine livers were (1.750). The difference between the residue of enrofloxacin of poultry liver samples and that of bovine and ovine liver samples was significant at (P<0.05). [Sultan IA (2014)
