“…Next to DON, there are other masked forms of DON, deoxynivalenol-3-glucoside (D3G) or 3(15)-acetyldeoxynivalenol (3(15)-ADON), but changes among these forms are still insufficiently known (Maresca, 2013). Pazderu et al (2016) suggested high importance of evaluating not only DON, but all DON forms simultaneously. Fusarium head blight tolerant cultivars may contain a high proportion of grain which is apparently healthy, but contain excessive DON levels.…”

The contamination of unprocessed winter wheat grain by mycotoxins was detected on the territory of the Slovak Republic with the focus on primary producers, after the harvest in 2009-2010, 2010-2011 and 2011-2012 growing periods. Mycotoxin levels were determined by high performance liquid chromatography (HPLC) methods. Deoxynivalenol (DON) was the most common Fusarium toxin, detected in 85% of samples, 2% of samples exceeded the maximum level set by Regulation (EC) 1881/2006. Nivalenol (NIV) was detected in 63% of samples, T-2 toxin -in 73% and HT-2 toxin -in 79%. The mean concentration of DON was 368.4 µg kg -1 , for NIV -34.8 µg kg -1 , for T-2 toxin -38.2 µg kg -1 and for HT-2 toxin -29.9 µg kg -1 . Co-occurrence of DON with NIV was detected in 15.5% of positive samples and their co-occurrence with other mycotoxins represented additional 7.35%. Cooccurrence of DON with zearalenone (ZEA) was detected in 25.9% of positive samples. To prevent the occurrence of mycotoxins at levels considered harmful to human health, a number of measures are needed at different levels, from good agricultural practices, breeding for resistance, to adequate legislation, methods and programs for food control that influence food security.

“…Experimental determination of the concentration of mycotoxins is quite complicated. Moreover, it is infl uenced by processes occurring inside the seed and varies with time (Pazderů et al, 2016;Maul et al, 2012;Wolf-Hall, 2007). Detailed analysis of the transfer of fi ve Fusarium toxins -deoxynivalenol (DON), HT-2 toxin (HT-2), zearalenone (ZON) and sum of 15-and 3-acetyl-deoxynivalenol (ADONs) -from fi eld barley through malt to beer was investigated in detail by K. Lancova and co-workers (Lancova et al, 2008).…”

Deoxynivalenol (DON) together with two acetylated derivatives, 3-acetyldeoxynivalenol (3-ADON) and 15-acetyldeoxynivalenol (15-ADON) occurs in cereal grains and their products. Co-occurrence of DON and acetylated derivatives in cereal grain is detected worldwide. Until now, DON and its derivatives have been considered equally toxic by health authorities. In this study, we analysed 103 samples of spring wheat grain, originating from the fields of different production systems in Lithuania, for the co-occurrence of type-B trichothecenes (DON, 3-ADON, 15-ADON). The samples were classified according to the production system-organic, sustainable and intensive. Mycotoxin levels in the spring wheat grain samples were determined by the HPLC method with UV detection. The type-B trichothecenes were found to be present at higher concentrations in the grain from the intensive production system. Eighty-one percent of the spring wheat grain samples from the intensive production system were co-contaminated with a combination of DON+3-ADON+15-ADON, 1% with DON+3-ADON. Additionally, DON+15-ADON and DON were found in 5% and 10% of the tested samples, respectively. Two percent of the samples were free from mycotoxins. In the grain samples from the sustainable production system, DON and a combination of DON+3-ADON showed a higher incidence - 47% and 23%, respectively. The samples with a combination of DON+3-ADON+15-ADON accounted for 18%. Completely different results were obtained from the analyses of organic grain samples. A large number of the organic spring wheat grain samples were contaminated with DON+3-ADON (55%) or DON (36%). The combination of DON+3-ADON+15-ADON was not present, while DON+15-ADON was present in 9% of the samples tested. The production systems did not lead to significant differences in mycotoxin levels, although a trend toward higher incidence and higher contamination was observed for the samples from the intensive and sustainable production systems.
