ST. PAUL, Minn. (AP) - The top turkey producing county in the top turkey state has reported another case of bird flu.

The Minnesota Board of Animal Health reported presumptive positive test results Tuesday from a 39th flock in Kandiyohi County. The west-central county is the center of Minnesota's turkey industry and it's been hit harder than any other county in the state by the H5N2 avian influenza virus.

The new case raises the number of affected farms in Minnesota to 104. The outbreaks have cost Minnesota turkey and chicken producers more than 8.4 million bids.
