University of Wisconsin–Madison expert Keith Poulsen, who specializes in zoonotic diseases, has been closely monitoring the situation where a highly pathogenic strain of avian influenza has been detected in dairy herds in Texas, Kansas, and Michigan. Poulsen emphasized that there is currently no evidence of the disease in Wisconsin, and there are no restrictions on animal movement between states at this time.

In an interview, Poulsen explained that the disease seems to be spreading from birds to cows, mainly affecting those in later stages of their milk cycle. He mentioned that migratory birds are the carriers of this highly pathogenic avian influenza, which has been a concern since 2022. Despite the spread in other states, there have been no reported cases in Wisconsin's domestic poultry flocks so far.

Regarding the impact on Wisconsinites, Poulsen assured that dairy products like pasteurized milk and cooked meat are safe for consumption. He also mentioned that the risk of human infection is currently low. However, he advised dairy farmers to be vigilant for signs of sickness in their herds, such as decreased activity, reduced milk production, and changes in milk consistency and color.

For those suspecting their animals may be affected, Poulsen recommended contacting a herd veterinarian promptly, who can then reach out to the Wisconsin Veterinary Diagnostic Laboratory or Department of Agriculture for further testing. Early detection is crucial in minimizing the spread of the virus and implementing necessary management changes on farms.

In conclusion, Poulsen emphasized the importance of early reporting and monitoring to prevent the potential spread of the disease within the state. While the situation is being closely monitored, Wisconsinites can be reassured that there is currently no significant risk to public health from this outbreak.
