SPOKANE, WA - An Eastern Washington farmer says he has no idea how genetically engineered alfalfa started growing in his fields. Joseph Peila says the alfalfa seeds were planted in the fall of 2010, and genetically modified seeds were not even approved by the federal government until January 2011. Peila farms near the town of Royal City and says he is speaking out now in order to protect other farmers. Peila sold 70 acres of his hay crop to an export broker this summer. Much of Peila's surprise, the broker's tests revealed some of the alfalfa was genetically modified. Tests showed the crop contained a low-level presence of a genetic trait called Round-Up Ready, meaning the plants were able to tolerate the well-known herbicide.
