|
An analytical method for the determination of flumequine in meats was developed and validated using high-performanceliquid chromatography with fluorescence detection. The samples were mixed with sodium sulfate and extracted with ethylacetate. After clean-up, the residues were dissolved in mobile phase. The calibration curves showed high linearity (r2=0.9979)within the concentration range of 0.1-1.0mg/kg. The limit of detection and limit of quantification were validated at 0.005 and0.017 mg/kg, respectively. The recoveries in fortified meats ranged from 90.8 to 101.1%. The method was then validated incorrespondence with the CODEX guidelines for flumequine residue in meats. Herein we monitored 150 samples of meats thatwere purchased in Korea (Seoul, Busan, Daegu, Daejeon, and Gwangju). Among the tested samples, flumequine was detectedin 1 of beef and 1 of pork at levels in the range of 0.048-0.080mg/kg. Overall, the flumequine residues in the tested sampleswere within the Maximun residue limit.
