Colorado mobilizes after avian flu hits Weld County egg farm

Colorado confirms a suspected avian flu outbreak at a Weld County egg farm, with CSU confirming the outbreak and the state awaiting final confirmation from USDA facilities in Iowa; Lt. Gov. Primavera has issued a verbal disaster declaration to coordinate response as authorities prepare mitigation efforts, marking the first commercial farm outbreak in Colorado since mid-2024 after years of culling in the egg and dairy sectors. Some workers tested positive during 2024 outbreaks, but none required hospitalization, and officials continue monitoring for human cases while containment measures take effect.
