Talks this week with the U.S. and South Korea about expanding beef trade have failed to bring the two sides any closer together. Officials were going over what should be considered boneless beef for export purposes and whether all shipments need to be screened for bone fragments with x-ray machines. USDA Secretary Mike Johanns said, "There were discussions, and I've been keeping track of those discussions, but at least today I can't show you anything that came out that I would point to and say that is progress." South Korea currently allows beef from animals less than 30 year of age if packers remove the brains, spinal cords and nervous tissue due to the risk of spreading mad cow disease.
