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 147 corn grain samples tested to date, initial surveillance of 2022 crop suggests an increase in the occurrence of Fumonisins (+10% points) and Aflatoxins (+7% points) while fewer samples have tested positive for B-Trichothecenes and Zearalenone vs. 2021 crop
• Additional details including mean contamination levels and risk by state can be found by downloading the full report.

• Based on the 41 corn silage samples tested to date, initial surveillance of 2022 crop suggests an increase in the occurrence of Fumonisins (+13% points) and B-Trichothecenes (+9% points) while fewer samples have tested positive for Zearalenone vs. 2021 crop.

• Based on the 7 corn grain samples tested to date, initial surveillance of 2022 crop suggests an increase in the occurrence of major mycotoxins vs. 2021 crop, but more sampling is suggested to better characterize this year’s contamination profile.
• Additional details including mean contamination levels and risk by province can be found by downloading the full report.

• Based on the 17 corn silage samples tested to date, initial surveillance of 2022 crop suggests a decrease in the occurrence of major mycotoxins vs. 2021 crop, but more sampling is suggested to better characterize this year’s contamination profile.
