A highly contagious strain of bird flu has struck a flock of backyard poultry in Wisconsin, prompting authorities to euthanize the birds amid ongoing concerns about the spread of the potentially deadly disease.
The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) confirmed a case of highly pathogenic avian influenza (HPAI) in a flock of backyard poultry in Rusk County on Thursday.
Authorities have not said how the herd became infected.
DATCP said all birds on the property have been euthanized and will not enter the food system.
HPAI, a highly contagious and often fatal virus for domestic poultry, has been circulating among wild and domestic birds in North America since December 2021, according to DATCP.
The illness is caused by influenza A viruses and its severity can vary depending on the strain and species affected.
The virus can be spread through contact with infected birds, wild birds or their droppings, as well as through contaminated equipment or clothing worn by people working with animals, according to DATCP.
When HPAI is confirmed in a flock of backyard poultry, authorities may establish a 10-kilometer surveillance zone, although surrounding poultry facilities are not subject to movement restrictions.
DATCP urged ranchers to take precautions to protect their herds, including washing hands, disinfecting equipment, restricting access to animals, and separating new animals for at least 30 days.
The agency also recommended poultry owners keep their birds indoors when possible.
