Meanwhile, a 14th commercial turkey farm in Minnesota has been tainted, following Friday's news that four additional farms has been struck. The West Central Tribune reports that the latest farm dealing with the virus is in Kandiyohi county, with 38,000 birds in the affected flock.
The Associated Press reported that the National Veterinary Services Laboratories in Iowa confirmed the avian influenza in a flock of 40,000 turkeys in Dickey County. Forum News Service notes it's that state's first confirmed case of the flu strain.
The AP noted that the flu strain was confirmed in a commercial turkey flock of 34,000 turkeys in Kingsburg County in eastern South Dakota. One previous case of the virus in South Dakota was found last week at a farm in Beadle County.
