Determination of Enrofloxacin Residues in Commercial Broilers Using High Performance Liquid Chromatography

The broad-spectrum antibacterial drugs are widely used in food producing animals. Suspected residues of these drugs in meat may have ill effects upon human health. The aim of the present study was to determine the enrofloxacin residues in broiler's meat and liver samples. Detection of enrofloxacin residues in meat (n = 75) and liver (n = 75) samples was performed by high performance liquid chromatography with UV detector set at 268 nm using C-18 column. Overall mean residual concentrations of enrofloxacin in meat and liver samples were 208 +/- 55 and 527 +/- 84 mu g/kg, respectively. This study revealed that 52% (39) meat and 78.7% (59) liver samples were positive for enrofloxacin, out of these 58.3% (21) meat and 71.2% (42) liver samples were having residual concentration above the maximum residual limits. So it can be concluded that the usage of this contaminated meat may cause resistance in consumers and seems to be a public health threat.
