Subject: Karnal bunt found outside regulated area in Texas
Publicada: June 25, 2001
Source: APHIS
USDA is adding Archer County, Texas, to the quarantined area for Karnal bunt (KB) after wheat seed at a local grain elevator tested positive for the fungus. Archer County is directly north of Young County, which was added to the regulated area along with Throckmorton County on June 8. USDA is also temporarily designating Baylor County, Texas, as a regulated area for KB after discovering that wheat harvested from Archer County was moved to elevators in adjacent Baylor County. This regulation is necessary in order to prevent the movement of grain in and out of Baylor County elevators while the determination is made as to whether KB is present.

While KB does not threaten human health, flour made from heavily infected wheat has an unpleasant odor and taste, jeopardizing its marketability. The disease also reduces crop yields.
