The invention belongs to the technical field of pesticide residue detection, and particularly relates to a high performance liquid chromatography-tandem mass spectrometry method for rapidly detecting the residual quantity of metaflumizone in animal-derived food. The method comprises the following steps: adding acetonitrile into animal-derived food to be detected, oscillating and extracting, centrifuging to obtain supernate, purifying the supernate, passing through an organic filter membrane, and quantitatively and/or qualitatively detecting metaflumizone-E and/or metaflumizone-Z in a sample by high performance liquid chromatography-tandem mass spectrometry on the filtered supernate, wherein the relation proportion of the animal-derived food to be detected to the acetonitrile is 1: 5-1: 2. The method is suitable for detection and quantification of metaflumizone-E and metaflumizone-Z in animal source samples such as eggs (egg white and yolk), chicken muscle, chicken fat and chicken liver. In this way, the pretr
