GMO crops became commercially available in the United States in 1996 and now constitute the vast majority of corn, cotton and soybean crops grown in the country. U.S. GMO cultivation grew rapidly from only 7 percent of soybean acres and 1 percent of corn acres in 1996, to 93 percent of soybean and 90 percent of corn acres in 2013. Certifiable organic crops cannot be grown from GMO seeds. The threat and actual occurrence of contamination of nonGMO crops by GMO crops harms many participants in markets where no detectable GMO presence is required or expected, including organic and non-GMO (often described as “identity preserved”). The topic of coexistence becomes even more complicated because organic and non-GMO farmers are taking a variety of precautionary measures to try to protect themselves from contamination and maintain their ability to sell into specific markets, while GMO growers are not specifically required to mitigate the risk of contamination.
