Trouw Nutrition has warned that early testing of corn for 2021 feed production has revealed high mycotoxin levels, particularly aflatoxins in India, deoxynivalenol in Mexico and South Africa, and T2/HT2 in South Africa. The company's global analysis of feed ingredients and complete feeds in 2020 revealed over 80% contamination, with the average concentrations of certain toxins increasing in 2020. Despite a decrease in the concentrations of four mycotoxins, the average concentrations of ochratoxin A and T2/HT2 increased. Each grain and protein source examined had varying percentages of contamination. The company emphasized that grains and grain by-products contribute more to the final feed's mycotoxin concentration than protein sources.
