"Japan, the biggest importer of soft white wheat grown in Oregon and Washington, postponed a 25,000-ton order from a Portland grain shipper Thursday, the first market fallout after the discovery of genetically engineered wheat plants growing in an eastern Oregon field where they shouldn't have been."
"Officials at Columbia Grain, which ships from facilities at the Port of Portland, said Japanese buyers are simply being cautious and are waiting for results from an investigation underway by the U.S. Department of Agriculture's Animal Plant Health Inspection Service.
It's not clear how the genetically modified plants ended up in the field or if they will be found on surrounding farms, too. The last field tests of this strain of genetically modified wheat in Oregon were in 2001."
