This document specifies a screening method for the determination of aflatoxin B1, deoxynivalenol, fumonisin B1 and B2, ochratoxin A, T-2 toxin, HT-2 toxin, and zearalenone in foodstuffs by high performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS/MS).

The aim of the screening method is to determine whether a certain pre-defined concentration (the screening target concentration, STC) is exceeded or not. The result of the screening is either ´negative´ or ´suspect´. ´Negative´ (screen negative) means that the targeted mycotoxins are not detected or potentially present but below the STC. ´Suspect´ (screen positive) means that the established cut-off value is exceeded and the sample can contain one or more mycotoxins at a concentration higher than the STC.

For full identification and accurate quantification a confirmatory quantitative analysis method is required which is outside the scope of this document.
