95% of mycotoxins in the feed are produced in the field. There is not necessarily visible fungal growth in contaminated grains. The EU has set maximum values for the individual toxins in feed, but we have to remember that reaction of contamination with several toxins is unpredictable - even in small concentrations.
The situation is not stable from one year to another. Wet and cool conditions favor the growth of Fusarium molds which can infect the plant during all growth periods and the level of toxins may increase.
This year we have experienced wet and cool weather during the blossom-time of crops which increases the risk of a high toxin pressure.
The forecast for the coming harvest indicates potentially moderate to high levels of DON in European wheat. Results of statistical analysis reveal that many parts of Europe can expect potentially harmful levels of mycotoxin contamination in the upcoming 2021 wheat harvest.
Harvests in the southern European countries have an average of 45% risk to contain more than 150 ppb DON. The risk for central and eastern European countries is 34% and 32%, respectively. The estimated risk for northern European countries is 31%. (Source: Biomin)
