The State Veterinarian, as designee of the Commissioner of Agriculture, has concluded that HPAI H5N1 clade 2.3.4.4b genotype B3.13 has been detected in dairy cattle in thirteen US states, including Colorado. As of August 14, 2024, Colorado has had 64 dairies affected with HPAI which represents approximately 75% of Colorado's licensed dairy cow facilities. In July 2024, this outbreak led to spillover to three commercial poultry facilities resulting in the death and depopulation of 3.3 million domestic chickens in Colorado, which represents more than 65% of Colorado's table egg laying hen population. HPAI is a communicable disease known to infect poultry and waterfowl, both domestic and wild, with occasional spillover to mammals including dairy cattle. Further, HPAI may be zoonotic, representing a threat to humans who may come into contact with its pathogens. HPAI is a reportable animal disease in the state of Colorado in any species.

HPAI has also been positively identified in the state of Colorado in both poultry and dairy cattle. This emergency rule will protect the health, safety, and welfare of Colorado's poultry and livestock industries and of Colorado's residents by limiting the opportunity for the spread of HPAI in Colorado.
On April 24, 2024, the Animal and Plant Health Inspection Services (APHIS), United States Department of Agriculture, issued a federal order (Federal order Requiring Testing for and Reporting of Highly Pathogenic Avian Influenza (HPAI) in Livestock) to prevent the spread of HPAI, which order (issued April 24, 2024) is incorporated herein by reference, later amendments of editions not included.
