WELD COUNTY, Colo. — State officials issued a disaster declaration after a suspected case of bird flu was discovered at a commercial egg farm in Weld County. 

Lt. Governor Dianne Primavera (D) verbally issued the declaration on Thursday evening. Governor Polis (D) is in Washington D.C. to attend the Colorado River negotiation meeting.

The Colorado Department of Public Health and Environment (CDPHE) said they were informed of a presumptive positive case of highly pathogenic avian influenza at a poultry farm in Weld County. The state is now waiting for confirmation of that positive test from the U.S. Department of Agriculture in Iowa.

The disaster declaration “enables state agencies to continue to properly coordinate for mitigation of disease spread, response, consequence management, and recovery efforts.”

Currently, CDPHE said there are no suspected or confirmed cases of avian influenza in humans, and that they will be working to help protect farm workers during the suspected outbreak. The department said they are working with the Colorado Department of Agriculture and the Weld County Health Department to ensure workers at the farm are using personal protective equipment and being screened daily for any symptoms. 

The last human cases of bird flu in Colorado were in 2024, when at least ten people in the state ended up contracting the virus. This included a dairy farm worker who contracted the H5N1 avian flu strain after having direct contact with dairy cows that were infected, and nine people who worked at two different poultry farms in Weld County, including workers who were culling birds that had tested positive for avian flu.
