DOI: 10.1002/sscp.202000091 The cover picture shows a useful and effective assay for the determination of residual alachlor and its metabolites in beef muscle, liver, milk and egg by liquid chromatography‐tandem mass spectrometry (LC‐MS/MS). The proposed method uses a simple extraction with methanol followed by dispersive (QuEChERS) and solid‐phase extraction (SPE) cleanup. The recovery values fortified at 0.02 and 0.2 μg/g was 70.4–107.6% with RSD ≤ 7.1%.
