Mycotoxin Survey in US and Canada: June 2022 Update

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 trends of each of these feed ingredients regarding mycotoxin occurrence and contamination levels.

• Of the 284 corn samples tested, surveillance suggests that mycotoxin occurrence is somewhat increased compared to 2020, with the greatest shifts in B-Trichothecenes (+11% points) and Zearalenone (+7% points).

• Of the 75 corn by-products samples tested (primarily DDGS and corn gluten feed), surveillance suggests that mycotoxin occurrence is slightly increased compared to 2020.

• Although based on a limited data set of 14 corn samples, surveillance suggests that mycotoxin contamination is somewhat lower compared to 2020, with the exception of Zearalenone (+8% points).
