Development and Validation of an Ultra-Performance Liquid Chromatography-Tandem Mass Spectrometry Method to Determine Maduramicin in Crayfish (Procambarus clarkii) and Evaluate Food Safety.

ABSTRACT: Maduramicin (MAD) is widely introduced into aquatic environments and results in the contamination of fish products. Worryingly, the consumption of MAD-contaminated crayfish (Procambarus clarkii) may induce symptoms of Haff disease. In this study, to monitor this potential contamination and to understand the residue and elimination characteristics of MAD in edible tissues of crayfish, a sensitive and efficient ultra-performance liquid chromatography-tandem mass spectrometry method was developed, validated, and applied. After extraction with acetonitrile and purification by solid-phase extraction column, multiple-reaction monitoring mass spectrometry with positive ionization mode was used to determine MAD's residues. The limits of detection and of quantification were 6 μg·kg-1 and 20 μg·kg-1
