No. We've set up a system to make sure there are no other GMO species. In the case of Roundup Ready alfalfa, you can't tell it from the conventional type. It's impossible. You can't tell the plants apart.
We have set this up to take care of our other three crops: canola, soybean, and corn. We've taken extraordinary steps to ensure we can maintain our market share through our producers working extra hard to keep those contaminants out of their fields, and through the separate processing. If it is discovered, the seed stays here.
