Simultaneous determination of multi-class veterinary drugs in chicken processed foods and muscle using solid-supported liquid extraction clean-up.

•A new analytical method for 37 veterinary drugs in chicken processed foods and muscle was developed.•Two-step extraction enabled effective extraction of analytes from highly lipid samples.•SLE clean-up eliminated lipid matrices, and almost all analytes were observed with acceptable matrix effects.•Applying the developed method, residual veterinary drugs in processed foods were detected.
