BIOMIN Mycotoxin Survey in US and Canada: December 2020 Update
Our December 2020 update from the annual Biomin® PROcheck mycotoxin survey comprising 426 samples from 26 states of US corn harvested in 2019, corn by-products, and corn silage is here.
15.12.2020US and Canada Reports
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
Ocharatoxin A (OTA)
Summary
The survey results represent samples sent in for surveillance testing only and does not include any sample submitted following clinical signs. In the report we discuss preliminary trends of each of these feed ingredients regarding mycotoxin prevalence and contamination levels.
USA Corn
- 92 corn samples were tested
- 89% of samples were positive for at least one mycotoxin vs. 96% in 2019
- 51% of samples had more than one mycotoxin, vs 71% in 2019
- Average contamination levels:
Mycotoxins | 2020 | 2019 |
A-Trichothecenes | 1% | 2% |
B-Trichothecenes | 64% | 81% |
Fumonisins | 68% | 78% |
Zearalenone | 21% | 46% |
Aflatoxins | 2% | 3% |
Ochratoxin A | 1% | 0% |
- Overall, the mycotoxin contamination in 2020 corn seems relatively lower in comparison to 2019 corn.
USA Corn By-Products
- 46 corn by-product samples (DDGs and corn gluten meal) were tested
- 98% of samples were positive for at least one mycotoxin vs. 99% in 2019
- 98% of samples had more than one mycotoxin, vs 99% in 2018
- Average contamination levels:
Mycotoxins | 2020 | 2019 |
A-Trichothecenes | 2% | 6% |
B-Trichothecenes | 98% | 100% |
Fumonisins | 96% | 98% |
Zearalenone | 93% | 94% |
Aflatoxins | 7% | 2% |
Ochratoxin A | 6% | 4% |
- Overall, the mycotoxin contamination in corn by-products in 2020 seems similar to 2019.
Canadian Corn
- 14 corn samples were tested
- 88% of samples were positive for at least one mycotoxin vs. 96% in 2019
- 50% of samples had more than one mycotoxin, vs 71% in 2019
- Average contamination levels:
Mycotoxins | 2020 | 2019 |
A-Trichothecenes | 29% | 27% |
B-Trichothecenes | 71% | 85% |
Fumonisins | 36% | 32% |
Zearalenone | 14% | 27% |
Aflatoxins | 0% | 2% |
Ochratoxin A | 0% | 0% |
Overall, the mycotoxin contamination levels in 2020 corn are similar to 2019 corn.
