For the first time, 39 of the major anthelmintics can be detected in one rapid and sensitive LC-MS/MS method, including the flukicides, which have been generally overlooked in surveillance programs. Utilizing the QuEChERS approach, residues were extracted from liver and milk using acetonitrile, sodium chloride, and magnesium sulphate. Extracts were purified by dispersive SPE using magnesium sulphate and octadecylsilane before injection onto the LC-MS/MS. The method was single laboratory validated according to 2002/657/EC criteria. The limit of quantitation of the method was 5 ug/kg for all residues except dichlorvos (10 ug/kg).
