Later today a group of people from places as far away as Japan and Spain will go to a farm in Rosemount, Minnesota, where researchers are improving ways to grow crops that are not genetically modified. The trip is part of the first Midwest Specialty Grains Conference in Minneapolis. Attendees are interested in food that has been grown and kept separate from genetically modified food, also known as genetically modified organisms (GMO). Conference organizers say wordwide demand for non-GMO soybeans and grains is growing rapidly. Morning Edition host Cathy Wurzer spoke with Bob Zelenka, executive director of the Midwest Shippers Association which is sponsoring the conference.
