Mycotoxins are potentially toxic secondary metabolites produced by different species of fungi. The main relevant species occurring on cereals are Penicillium sp., Fusarium sp. and Aspergillus sp. The fungal contamination can either occur on the field or during storage. Estimations are given that approximately 25% of all crops are contaminated with mycotoxins. The type and amount of contamination varies with climate conditions. As the contamination can result in serious health issues, mycotoxin analysis is an important part of routine food control.1, 2
Mycotoxins are potentially toxic secondary metabolites
produced by different species of fungi. The main relevant
species occurring on cereals are Penicillium sp., Fusarium
sp. and Aspergillus sp. The fungal contamination can
either occur on the field or during storage. Estimations
are given that approximately 25% of all crops are
contaminated with mycotoxins. The type and amount of
contamination varies with climate conditions. As the
contamination can result in serious health issues, mycotoxin
analysis is an important part of routine food
control.1, 2
For cereals and baby food, the European Union (EU)
legislation currently sets maximum levels (ML) for the
following mycotoxins: deoxynivalenol, zearalenone, T-2
toxin, HT-2 toxin, fumonisin B1, fumonisin B2, aflatoxin
B1, B2, G1, G2 and ochratoxin A.3-6 The European Food
Safety Authority (EFSA) is continuously examining the
occurrence and health risks of further mycotoxins. One
of the main current topics of interest is the acetylated
deoxynivalenol metabolites and deoxynivalenol-3-glucoside.
7 For some mycotoxins, e.g. sterigmatocystin, which is
related to aflatoxins, EFSA could not determine the risk
due to lack of data.8
This application note presents a simple and fast
multi-mycotoxin method that covers the legislated
mycotoxins as well as 3- and 15-acetyl-deoxynivalenol,
deoxynivalenol-3-glucoside, nivalenol, its acetyl derivative
fusarenon X and sterigmatocystin. The sample preparation
follows a simple dilute-and-shoot approach after
extraction of cereals and maize with a mixture of
acetonitrile/water. The analysis was carried out on a
Thermo Scientific™ UltiMate™ 3000 LC system coupled to
a Thermo Scientific™ TSQ Endura™ triple quadrupole
mass spectrometer. The method was evaluated regarding
the LOD/LOQ limits, linearity and matrix effects
