Bird flu is confirmed at a third dairy in northwest Iowa as state and federal officials are trying to find out how the virus spreads between farms and livestock. On Wednesday, Iowa’s ag department confirmed avian influenza at a dairy farm with 17-hundred cows in Sioux County. State veterinarian Jeff Kaisand says most cows recover within a few weeks, unlike infected poultry, which are euthanized.
It’s the second case in Sioux County and the third in the state after the virus was first found in an Iowa dairy in O’Brien County last week. Kaisand says one priority is trying to figure out how avian influenza spreads between farms and livestock.
The Department of Agriculture and Land Stewardship recently started testing dairies within a 12-mile radius of infected poultry farms.
