Background. USDA's Animal and Plant Health Inspection Service has launched an investigation into how an unapproved GMO wheat variety developed by Monsanto Co. but never approved by federal regulators came to be growing in Washington. It was the third such finding since 2013. There are no commercially approved varieties of GMO wheat. The discovery, announced last week, prompted importers such as Japan and South Korea to suspend purchases of some US wheat.
Meanwhile, South Korea's Ministry of Food and Drug Safety said on Friday that it has not found any GMO wheat in tests on imported wheat and flour from Washington state after receiving testing supplies on Aug. 1. The fifth-largest buyer of U.S. wheat said it will continue testing incoming US wheat and reject loads containing any rogue wheat.
