DIN EN 17279:2018-08

This standard describes a fast and straightforward LC-MS/MS-based method for the screening of ochratoxin A, aflatoxin B1, deoxynivalenol, zearalenone, T2- and HT-2 toxin, and fumonisin B1 and B2 in foodstuffs (cereals, cereal products, nuts, dried fruit, and beverage, excluding foods for infants and young children) by LC-MS/MS. The aim of the screening method is to test compliance of foodstuff with regulatory limits or to determine whether a certain pre-defined level (the screening target concentration, STC) is exceeded or not. The result of the screening analysis 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 an established cut-off level is exceeded and the sample may contain one or more mycotoxins at a level higher than the STC. For full identification and accurate quantification a second confirmatory quantitative analysis method is required which is outside the scope of this standard.
