WILLMAR — Seven more poultry flocks diagnosed with bird flu were reported Monday, including the fifth commercial flock of turkeys in Kandiyohi County and the first sites in Renville and Swift counties.

Swift County’s flock of 145,000 commercial meat turkeys is among the largest flocks to date diagnosed with highly pathogenic H5N1 avian influenza, according to the state Board of Animal Health’s daily online update.

The first reported infection site in Renville County involves 76,381 commercial meat turkeys.

The additional flock in Kandiyohi County has 21,250 commercial turkey breeder hens. The four previous reports in Kandiyohi County involved two flocks of breeding hens and two flocks of broiler turkeys.

Stearns County now also has five infection sites with an additional flock of commercial meat turkeys numbering 26,293. There was a report from a backyard producer and the others are all meat flocks .

Other new infection sites reported Monday were a flock of 20,438 in Waseca County, 30,000 birds in Otter Tail County and 38,000 in LeSueur County, all commercial meat turkeys.

According to the National Animal Health Council, the inventory of flocks diagnosed with avian influenza is now 1,373,664 encompassing 28 infection sites. The new reports released on Monday included confirmed diagnoses from April 7-9.

The first cases of the disease in Minnesota — which is fatal to domestic poultry — were confirmed March 25, according to the Board of Animal Health.

A previous report has been reclassified by the Animal Health Council. The first infection site in Waseca County confirmed on April 5 was originally listed as a slaughter location, but its production type has since been changed to commercial meat turkeys.

According to information from the Animal Health Council, responders enter data with what is known when the case arises, and quality control staff regularly review the data later to ensure consistency and can make changes to give a more precise description of the premises.

There were two reports from backyard poultry producers, three from commercial turkey breeding hen flocks in Kandiyohi County, and the rest of the 28 sites were meat turkeys.

Other affected counties include Becker, Big Stone, Dodge, Lac qui Parle, Meeker, Morrison and Mower.
