The two new cases reported Tuesday are both in commercial turkey flocks – one each in Kandiyohi and Morrison counties.

There are now four commercial turkey flocks affected by avian flu in Kandiyohi County; two each in Morrison and Stearns counties; and one each in Becker, Dodge, Le Sueur, Lac qui Parle and Meeker counties – as well as backyard flocks in Mower and Stearns counties.

The first of those cases was confirmed on March 25.

In total, the affected flocks so far total more than 630,000 Birds.

Birds in affected flocks are euthanized as part of efforts to keep the virus from spreading.

The US Centers for Disease Control and Prevention has said the H5N1 strain of avian influenza is a low risk to the public. No human cases of avian influenza have been detected in the US

But the Outbreak represents a serious Threat to Minnesota’s Turkish industry, with nearly 700 Farms that raise about 40 million birds a year, the now of any state.

In 2015, 9 million birds in Minnesota were killed by the virus or euthanized to slow its spread.

The U.S. Department of Agriculture team is helping Minnesota agencies respond to the current outbreak, including quarantining infected flocks, disease surveillance and coordinating logistics and finances.

Poultry producers in the state had been on high alert for weeks, taking steps to increase biosecurity, after the virus was detected in neighboring states, including Iowa and South Dakota.

Dr. Carol Cardona, a professor of avian health at the University of Minnesota College of Veterinary Medicine, said this particular virus is a relative of the 2015 strain – a highly pathogenic variant found in wild birds. She said that’s why the cases are popping up in different areas of the state, and not necessarily spreading from farm to farm.

Cardona said that pattern also shows that farmers’ Biosecurity measures are largely working to keep the virus out of their flocks – or to quickly detect positive cases and depopulate the Birds to keep it from spreading elsewhere.
