The Developments of QuEChERS in Veterinary Drug Residue Analysis of Animal-origin Foods

In recent years,the food safety problem of animal-origin foods increasingly becomes one of the focus of the government and the society. The drug residue of animal- origin foods seriously has impaired the environment and human health,and the existing methods of veterinary drug residues have the disadvantages of pretreatment complexity,time-consuming and detecting singleness,low sensitivity. Qu ECh ERS is quick,easy,cheap,effective,rugged and safe method for pesticide multi- residue analysis based on dispersive solid phase extraction, combined with high sensitivity and selectivity of high performance liquid chromatography mass spectrometry( HPLC / MS / MS),has been widely applied in the veterinary drug residues in animal food detection. The principle,characteristics,the basic step of Qu ECh ERS method,and the application progress of Qu ECh ERS-HPLC-MS / MS in the field of veterinary drug residue analysis were described.
