More than 40 cows on a central Minnesota dairy farm have fallen ill with avian flu. This morning, the Minnesota Board of Animal Health confirmed it's the first case of the disease in a dairy herd in the state.

Health officials have confirmed cases in 10 other states around the country, including neighboring South Dakota. Dr. Brian Hoefs, state veterinarian and executive director of the animal health board, joined MPR News guest host Nina Moini to break down the situation.
