An examiner demonstrates the process of analyzing a genetically modified wheat sample, during a photo call at the Ministry of Food and Drug Safety in Seoul May 31, 2013. South Korean millers said on Friday they would suspend imports of U.S. wheat until the results of tests by the Asian nation’s government on whether shipments have been tainted by an unapproved genetically modified strain of the crop. U.S. officials have been racing to quell alarm following news that the strain, developed by biotech giant Monsanto Co, was found in an Oregon field late last month.
