Bird flu in dairy cattle reported for first time in Iowa, Minnesota as outbreak spreads

An outbreak of bird flu in dairy cows has now reached 11 states after Iowa and Minnesota each confirmed their first positive case.

The detections add to a widening spread of the virus in the U.S., with bird flu confirmed in over 80 herds across the country. Three farmworkers have tested positive for the virus, including one who reported respiratory symptoms.

The case in Iowa, which was announced Wednesday and is still pending final confirmatory testing, was detected in the northwestern county of O’Brien, according to the state’s Department of Agriculture and Land Stewardship. O’Brien neighbors Sioux County, which is where an egg farm recently reported one of the worst outbreaks in nearly two years, affecting 4.2 million birds.
