Minnesota tops nation in wild birds confirmed dead from bird flu
The deadly bird disease is back this spring, and, in fact, never left over the winter
By John Myers
Today at 6:00 AM

DULUTH — Highly pathogenic avian influenza is back killing domestic poultry and wild birds in Minnesota again this spring as huge flocks of migratory birds carry it north for another season.

But, in fact, the deadly bird disease never left the state, even over our long winter, with birds dying in December and January and some new research showing the killer flu virus may survive even in Minnesota cold lake water — with no host bird — during the winter.

That's the update from wildlife biologists as the great spring migration descends on Minnesota, as the snow line recedes north and ice on lakes and rivers begins to let loose.

Since the disease was first reported in Minnesota just over a year ago, some 566 birds have been tested and confirmed carrying the H5N1 strain of bird flu that's been expanding worldwide since 2020, according to data from the U.S. Department of Agriculture.

Clinical signs included increased mortality. Depopulation and disposal were completed 10 May 2023. The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Animal Health and Wildlife Officials, are conducting comprehensive epidemiological investigations and enhanced surveillance in response to the HPAI H5N1 related events in non-poultry species. Affected population counts are based on estimated inventories from the date the outbreak was first reported to WOAH. According to article 10.4.1.4 of the Terrestrial Animal Health Code, Member Country should not impose bans on the international trade of poultry commodities in response to notification of infection with any Influenza A viruses in birds other than poultry.

Duck Creek Quarry and trails closed after test results point to suspected bird flu
by Ashley Kaster, FOX 11 NewsThu, January 4th 2024

HOWARD (WLUK) -- Preliminary test results show the bird flu is the likely cause of multiple dead geese recently found at Duck Creek Quarry in Howard.

In December, nearly three dozen geese were found dead in the quarry area.

Some of the dead birds were sent to Madison to be tested by the DNR.
..
Those test results point to suspected HPAI (bird flu) infection, animal control/humane officer Matt Atkinson said Thursday.​
