Because of issues in 2009 and 2010 wheat, FDA has revised standards regarding Vomitoxin (deoxynivalenol or DON) for the first time since 1993.

FDA has added gluten feeds and meals to the list of grains and grain byproducts subject to the 30-ppm DON advisory limit when fed to dairy, beef and feedlot cattle more than four months old. Looking at the total ration fed, the limit is 10 ppm for beef cattle and 5 ppm for dairy cattle.
