Food safety: Monitoring of organophosphate pesticide residues in crops and food

Organophosphate (OP) pesticides are used globally today, to control a wide range of insect pest species in agriculture, homes, and gat-dens, as well as in veterinary practice. OP pesticide residues in crops, food and food by-products are both a health and international trade issue. At present, QuECHER, matrix solid phase dispersion (MSPD), gel permeation chromatography (GPC), SPE, GC-FPD, GC-NPD, GC-MS, HPLC-MS, and other methods are widely used to detect OP pesticides residue in food. New issues at China Agricultural University (CAU) such as molecular imprinting, matrix effects, storage stabilities and chiral separation of OP pesticides are addressed in this article.
