Immunochemical Assays for Determination of Organophosphorus Pesticides in Milk

The detection of pesticide residues is an important task in ensuring the safety of milk. In the last decade, organophosphorus insecticides have been used, but they also pose a serious risk because of their high toxicity. For fast screening of milk, immunochemical methods of analysis are appropriate. Enzyme-linked immunosorbent assay is the most common assay mode and base of many commercialized assay kits. Residues of some organophosphorus compounds in milk and dairy products determined by ELISA are shown. For fast screening of pesticides, the lateral flow strips are also described. The advantages of a new developed method MNPs-based immunoassay for determination of phosphorus pesticides in milk was described and some publications were represented. In recent years, simultaneous identification of more than one pesticide is increasingly perceptual, that way the examples for multi-immunoassays for determination of organophosphorus pesticides was presented.
