Bird Flu Outbreak in Colorado: Five Workers Infected, Millions of Chickens to Be Culled

Five Cases Confirmed Among Poultry Cullers

Five workers involved in culling poultry at a farm in northeast Colorado have tested positive for the highly pathogenic avian influenza (bird flu) virus, health officials announced over the weekend. This brings the total number of human bird flu cases in the United States to ten since agricultural workers began culling infected birds late last month.

Major Outbreak in Weld County

The outbreak in Colorado's Weld County is the first at a commercial poultry facility in the state since February and only the second since December 2022. Nearly 18 million chickens will be euthanized to contain the spread of the virus, marking a significant resurgence of bird flu in the United States.
