VINEETHAAbstract The present study was undertaken to investigate the presence of Enrofloxacin residues in 20 bovine milk samples which was conducted in Pudussery and Perumatty Panchayat of Palakkad district. Enrofloxacin in positive samples was detected and quantified using high performance liquid chromatography (HPLC). A linear calibration curve was obtained with a correlation coefficient of 0.9864 while average recoveries were greater than 96.8% with RSD value of 0.54%. Out of 20 milk samples that were analyzed 2(10%) sample had detectable residue levels for enrofloxacin and it was above the recommended maximum residue limit. The method described in this study would be useful for routine monitoring of enrofloxacin residues in milk.
