title: Multiresidue method for pesticide residue analysis in food of animal and plant origin based on GC or LC and MS or MS/MS.
abstract: A multiresidue method based on GC or LC and MS or MS/MS for the determination of 204 pesticides in diverse food matrixes of animal and plant origin is described. The method can include different stages of cleanup according to the chemical characteristics of each sample. Samples were extracted using accelerated solvent extraction. Those with a high fat content or that contained chlorophyll required further purification by gel permeation chromatography and/or SPE (ENVI-Carb). The methodology developed here was fully validated; the LOQs for the 204 pesticides are presented. The LOQ values lie between 0.01 to 0.02 mg/kg. However, in some cases, mainly in baby food, they were as low as 0.003 mg/kg, thereby meeting European Union requirements on maximum residue levels for pesticides, as outlined in European regulation 396/2005 and the Commission Directive 2003/13/EC. The procedure has been accredited for a wide scope of pesticides and matrixes by the Spanish Accreditation Body (ENAC) following ISO/IEC 17025:2005, as outlined in ENAC technical note NT-19.
