Should you worry about mycotoxins in DDGS?
When mycotoxin-contaminated corn is used to make ethanol, mycotoxins will be found in the dried distillers grains with solubles (DDGS), not the ethanol.
And, they will be more concentrated in the DDGS than in the contaminated corn, explains Heather Dann with the W.H. Miner Agricultural Research Institute in Chazy, New York.
During 2009 to 2011, DDGS samples were collected from eight ethanol plants in the Midwest and analyzed for mycotoxin levels. The survey results were published this year in the Journal of Agricultural and Food Chemistry.
In the February 2012 Miner Farm Report, Dann summarizes what the survey found for five types of mycotoxins.
“Based on the results of the survey, it looks like we don’t have to worry about DDGS being a primary source of mycotoxins under normal growth conditions,” she says.
