Colorado Declares Disaster Over Presumptive Bird Flu Outbreak at Weld County Egg Farm

The order activates Colorado’s emergency plan to mobilize resources pending federal lab confirmation of the presumptive case.

Overview

  • Lt. Gov. Dianne Primavera issued a verbal disaster declaration while serving as acting governor, in coordination with Gov. Jared Polis.
  • State agriculture officials report a presumptive positive at an egg-laying facility that houses about 1.3 million chickens after an elevated mortality report.
  • Colorado State University identified the outbreak as highly pathogenic avian influenza, with USDA confirmation expected and response preparations underway.
  • The declaration activates the State Emergency Operations Plan, authorizes disaster funds, and allows emergency procurement and resource mobilization by the Office of Emergency Management.
  • Officials say this is the first commercial-farm detection since mid-2024, following three recent backyard cases in 2026 and mild, non-hospitalized worker infections reported in 2024.
