USDA LIFTS KARNAL BUNT RESTRICTIONS IN SOUTHEAST Release No 0084.97 Bethany Jones (301) 734-7280 bjones@aphis.usda.gov Jerry Redding (202) 720-6959 jredding@usda.gov USDA LIFTS KARNAL BUNT RESTRICTIONS IN SOUTHEAST WASHINGTON, March 17, 1997--The U.S. Department of Agriculture today announced it is lifting all Karnal bunt emergency action notifications currently in place in the Southeast. "We've extensively studied the situation in the Southeast and have concluded that Karnal bunt is not present there," said Terry Medley, administrator of USDA's Animal and Plant Health Inspection Service. USDA is basing its decision regarding Karnal bunt on the fact that bunted wheat kernels have not been found in any samples, whereas contamination with bunted ryegrass kernels was common. Researchers have shown that spores from ryegrass do not infect wheat. Some wheat samples collected during the national Karnal bunt survey contained spores similar in size and shape to those of the agent that causes Karnal bunt. Such spores were recovered in samples from Alabama, Florida, Georgia, and Tennessee. Wheat seed contaminated with these spores also was planted in South Carolina. "At this time we are no longer considering taking further regulatory action in the Southeast," said Michael V. Dunn, assistant secretary for marketing and regulatory programs. In the near future, USDA will publish a standard for determining the presence of Karnal bunt that will apply to all parts of the country. "Establishing this standard will ensure that all U.S. wheat producers and handlers are treated equitably with regard to Karnal bunt and that U.S. wheat has necessary certification to remain competitive in global markets," said Dunn. "These actions are consistent with USDA's objective to protect the U.S. wheat industry while limiting restrictions to areas where Karnal bunt disease occurs," said Dunn. # NOTE: USDA news releases and media advisories are available on the Internet.
