Potential for high Vomitoxin and Zearalenone in Corn, Corn Silage, and Corn Based Products
November 4th, 2009
We have been seeing very high levels of vomitoxin (DON) and zearalenone in corn, corn silage, and corn based products. The incidence is widespread with particularly high levels found in materials from Ohio, Indiana, and Pennsylvania. In corn grain, typical levels for Vomitoxin are 2 ppm to 18 ppm with some over 200 ppm; zearalenone at 1 ppm to 5 ppm with some samples over 8 ppm.
