A method based on ultra performance liquid chromatography-tandem mass spectrometry (UPLC- MS/MS) has been proposed for the determination of coccidiostat residues in chicken skin and fat. The sample was extracted with the combination of methanol, acetonitrile, and acetic acid, and cleaned-up by Sep-Pak tC18 solid phase extraction cartridge. Data acquisition under positive electrospray mode was performed by applying multiple reaction monitoring for both identification and quantification. The limits of detection and quantification for halofuginone and robenidine were 7 μg/kg and 20 μg/kg, respectively. The limit of detection of salinomycin, monensin, narasin, maduramicin, and lasalocid was 5 μg/kg, and limit of quantification was 15 p,g/kg. The recovery was 75%
