Nine states reported more highly pathogenic avian flu outbreaks, including four that reported more detections on commercial farms, according to the latest updates from the US Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS).

In a special avian influenza report, the University of Minnesota outlined outbreaks that impacted US turkey farms. Colorado reported an outbreak at a game bird farm in Prowers County that has 10,300 birds. In Minnesota, the virus hit a turkey farm in Wadena County that houses nearly 300,000 birds and a turkey farm in Dodge County, which has 10,000 birds.

Elsewhere, South Dakota reported two more outbreaks at turkey farms, one at a Hanson County facility that has 23,900 birds and another in Hamlin County at a location that has 58,100 birds. And Missouri reported an outbreak at a turkey farm in Osage County that houses 19,700 birds.

Seven states reported more virus detections in backyard birds: Colorado, Missouri, North Carolina, Oklahoma, Oregon, Texas, and Vermont.

Since the Eurasian H5N1 strain was first found in US poultry in February, outbreaks and resulting culling operations have led to the loss of a record 53.4 million birds across 46 states.
