Název v původním jazyce

Natural contamination of Czech malting barley with mycotoxins in connection with climate variability

Popis výsledku v původním jazyce

Ongoing climate change is affecting the geographical distribution of microscopic filamentous fungi and the mycotoxins they produce. In 2018–2020, the occurrence of the Fusarium mycotoxins deoxynivalenol, zearalenone, the sum of T-2 and HT-2 toxin, and ochratoxin A was monitored in a total of 450 samples of spring and winter malting barley from different regions of the Czech Republic. On average, the total contents of positive samples in the respective years were 40% for DON, 21% for ZEN and almost 79% for the sum of T-2, and HT-2 toxins. The ochratoxin A content was always below the detection limit except for three samples from the 2019 harvest. Mycotoxin levels were strongly affected by climate variability in the respective years. Very low concentrations of DON and ZEN were found in 2018–2019 with low rainfall and high temperatures. The highest level of contamination was found in the 2020 harvest, with 3.7% of samples exceeding the maximum level for DON and 2.2% for ZEN. The T-2 and HT-2 toxin levels increased year on year. This increasing contamination with T-2 and HT-2 toxins may indicate a change in the spectrum of fungal pathogens and their adaptation to new conditions.
