CHICAGO -- The U.S. Department of Agriculture on March 11 confirmed the discovery of highly pathogenic avian influenza in a commercial turkey flock in Arkansas, the third-largest U.S. turkey producer and home to Tyson Foods Inc., the nation's biggest chicken company.
The flock of 40,020 turkeys in Boone County is located within the Mississippi flyway, a migratory route along which the same strain of H5N2 bird flu has previously been identified in Minnesota and Missouri.
