Contagious Bird Flu Hits Wisconsin Poultry Flock

A strain of highly contagious bird flu has emerged in a backyard poultry flock in Wisconsin. This has led state officials to take action to cull the birds to prevent the spread of the disease. The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) confirmed that a case of highly pathogenic avian influenza (HPAI) has been detected in Rusk County.

The case was confirmed last Thursday, but authorities did not disclose the cause of the infection. All birds on the affected property were euthanized and are barred from entering the food system. This step is part of efforts to contain a virus that is often fatal to domestic poultry.

Officials have noted that since December 2021, this virus has been circulating among wild and domestic birds in North America. Caused by influenza type A viruses, the severity of the illness can vary based on the strain and bird species. The virus has the potential to spread through exposure to infected birds, either domestic or wild. Contaminated equipment or clothing of those handling the birds may also facilitate the spread.

To manage such outbreaks, authorities may establish a 10-kilometer surveillance zone around the affected area. However, there are no immediate movement restrictions on surrounding poultry premises. The DATCP has encouraged all livestock owners to adopt preventive measures. This includes washing hands, disinfecting equipment, limiting contact with animals, and quarantining new animals for at least 30 days.

Additionally, officials recommend keeping poultry indoors whenever feasible to reduce the risk of infection. This strategy is aligned with broader preventive efforts to secure the health of both poultry and humans in the area.
