Monsanto GMO wheat stored in Colorado through '11
The Roundup Ready wheat was never approved for commercial use and was supposed to be tightly controlled. Monsanto has said it suspects someone covertly obtained its wheat seed and planted it in the Oregon field to sabotage Monsanto's work with biotech crops.
The government and Monsanto have said there is no indication the GMO wheat made it into commercial supplies, but the finding has hit Monsanto and the wheat industry hard.
Monsanto has been named in several lawsuits and over the last month, exports of U.S. western white wheat have been curtailed as foreign buyers shun the U.S. supplies and demand assurances that none of the biotech wheat has contaminated the marketplace.
Wheat growers want the mystery solved.
"Determining how it happened would certainly make it easier for us to make sure ... that it doesn't happen again, regardless of whether it was sabotage or some accident," said Blake Rowe, chief executive of the Oregon Wheat Commission. "Our customers would like to know how it happened."
