Simultaneous determination of 13 mycotoxins in feedstuffs using QuEChERS extraction

Abstract Mycotoxins are secondary metabolites produced by various fungi and known to have a significant negative impact on human animal health. When feedstuffs contaminated with mycotoxins, their toxicities may be caused variety of diseases. In this study, the residual mycotoxins in were analyzed using LC–MS/MS incorporated QuEChERS extraction. Analytical method validation was performed for LOD, LOQ, linearity, recoveries consideration matrix effects prior analysis. They all reached accepted range level. Using 39 feedstuff samples (5 g) mycotoxin analysis, nine four major such as fumonisin B1 (FB1), deoxynivalenol, B2, zearalenone. Among them, FB1 detected at highest concentration 18.0943 mg/kg. The total sum fumonisins did not exceed maximum level (MRL) criterion set Korean Food Drug Administration. Altogether, intensive management should implemented proper routine monitoring, even concentrations exceeded over MRL levels because high frequent detection found study.
