Аннотация
A simultaneous rapid test method for pesticide residues in livestock products by LC-MS/MS was developed and validation tests were conducted. For the extraction method, the QuEChERS method was applied, and samples were extracted with acetonitrile, followed by salting out and dehydration. For purification, C18 and PSA columns were used instead of GPC. Based on the validity guidelines of the Ministry of Health, Labor and Welfare, 48 pesticide residues were evaluated at 0.01 μg/g and 0.1 μg/g for cattle muscle, swine muscle and milk. The trueness of the method for 43 pesticides in all three types of food samples was 70-120%, with satisfactory repeatability and within-laboratory reproducibility. Thus, this method demonstrated the usefulness of simultaneous rapid testing for pesticide residues in livestock products.
