Die Annotation des Normtextes ČSN EN 17279 (560023):

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
