1 Scope This document describes a method using isotopically labelled standards for the quantitative determination of aflatoxins B 1 , B 2 , G 1 , G 2 and M 1 (AFB1, AFB2, AFG1, AFG2 and AFM1), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEN), T-2 and HT-2 toxins (T-2 and HT-2) and fumonisins B 1 and B 2 (FB1 and FB2) in foods by liquid chromatography (LC) coupled with tandem mass spectrometry (MS/MS). A specific immunoaffinity column (IAC) clean-up is needed for aflatoxins (AFs) and OTA in food intended for infants and young children (e.g. infant cereals, milk-based powders), in spices, in dried fruits and in nuts. The method has been validated through an intercollaborative study on different commodity groups: cereals and cereal-based products including food for infant and young children, nuts, spices, dried fruits and milk powder. The measuring range of each mycotoxin in these naturally contaminated and/or spiked food samples were: — AFB1: 0,085 7 µg/kg – 11,4 µg/kg; — AFB2: ...
