Japan and South Korea are still testing the U.S. wheat they buy to make sure the grain is not contaminated with an experimental genetically modified version developed by Monsanto Co., but can stop the practice, the head of a U.S. wheat association said Thursday.
The two countries, which are among the top purchasers of U.S. wheat, have been sampling and testing all U.S. wheat they have purchased since last year, when news broke that a farmer in Oregon had found Monsanto's unapproved biotech wheat growing in his field, according to U.S. Wheat Associates, which markets American wheat to international buyers.
All of their test results on more than 5 million tons of wheat have been negative, it said.
