US discovery of rogue GMO wheat raises concerns over controls
Carey Gillam and Julie Ingwersen in Reuters: For global consumers now on high alert over a rogue strain of genetically modified wheat found in Oregon, the question is simple: How could this happen? For a cadre of critics of biotech crops, the question is different: How could it not?
The questions arose after the U.S. Department of Agriculture announced Wednesday that it was investigating the mysterious appearance of experimental, unapproved genetically engineered wheat plants on a farm in Oregon. The wheat was developed years ago by Monsanto Co to tolerate its Roundup herbicide, but the world's largest seed company scrapped the project and ended all field trials in 2004.
The incident joins a score of episodes in which biotech crops have eluded efforts to segregate them from conventional varieties. But it marks the first time that a test strain of wheat, which has no genetically modified varieties on the market, has escaped the protocols set up by U.S. regulators to control it.
"These requirements are leaky and there is just no doubt about that. There is a fundamental problem with the system," said Doug Gurian-Sherman, a scientist at the Union of Concerned Scientists who served on a biotech advisory subcommittee for the Food and Drug Administration from 2002 to 2005.
The discovery instantly roiled export markets, with Japan canceling a major shipment of wheat, a quick reminder of what is at stake - an $8 billion U.S. wheat export business....
