Each sample was tested for 6 major mycotoxin groups of:

• A-Trichothecenes (A-Trich): T-2, HT-2, Neosolaniol, Diacetoxyscirpenol
• B-Trichothecenes (B-Trich): Deoxynivalenol (DON/Vomitoxin), Acetyl-deoxynivalenol, Nivalenol, Fusarenon X
• Fumonisins (FUM): B1, B2, B3
• Zearalenone (ZEN)
• Aflatoxins (Afla): B1, B2, G1, and G2
• Ochratoxin A (OTA)

The survey results represent samples sent in for surveillance testing only and does not include any sample submitted following clinical signs. Below we discuss preliminary trends of each of these feed ingredients regarding mycotoxin prevalence and contamination levels.

• Based on the 283 corn grain samples tested to date, surveillance of 2022 crop suggests an increase in the occurrence of Fumonisins (+13% points), Aflatoxins (+3% points), and Zearalenone (+2% points) while slightly fewer samples have tested positive for B-Trichothecenes (-2% points) vs. 2021 crop.
