Avian Influenza

As of February 2022, Highly Pathogenic Avian Influenza (HPAI) has been detected in wild birds and poultry across many eastern states. USDA has published all detections of HPAI in poultry and wild birds on the APHIS website

The Colorado State Veterinarian’s Office is asking all poultry and bird owners to increase their biosecurity practices to keep the disease out of our domestic poultry in Colorado. 

Please visit USDA’s Defend the Flock Program to for in depth information about which biosecurity practices can keep your birds safe.

Weld02 & Weld03

The USDA’s National Veterinary Services Laboratory (NVSL) has confirmed the detection of Highly Pathogenic H5N1 Avian Influenza (HPAI) virus in two commercial operations in Weld County.

On Tuesday, June 7, 2022 the NVSL confirmed a detection in an egg layer facility. On Wednesday, June 8, the NVSL confirmed a detection in an adjacent pullet facility (on the same property). 

The State Veterinarian has issued a NEW Quarantine Order in parts of Weld County to limit movement of birds in and out of the area.

You can review the Order here: Order of Area Quarantine - Weld02 & Weld03 Control Area (June 8, 2022)

If you are a commercial or backyard poultry owner in the quarantine area, please use this form to report the status of your flock.

Please note: this information is being collected for tracking purposes only to ensure the health of flocks throughout the Quarantine Area. Your voluntary participation is encouraged so we can follow up with you in case of additional detections of HPAI. 

*It is critical to report sick birds or unusual bird deaths*

  • Sick birds or birds that have died from unknown causes:

    • Call the Avian Health Hotline at Colorado State University (CSU): (970) 297-4008

  • Dead birds:

    • Submit to the CSU Veterinary Diagnostic Laboratory in Fort Collins for free HPAI Testing: (970) 297-4008 or (970) 297-1281

  • Multiple sick birds or multiple unusual bird deaths:

    • Call the Colorado State Veterinarian’s Office (303) 869-9130 or the USDA-Veterinary Services Colorado Office (303) 231-5385

What Flock Owners Should Do

Owners should take the following steps to prepare:

INCREASE BIOSECURITY: It is extremely important for poultry owners to increase biosecurity measures to protect their birds from HPAI. The USDA Defend the Flock website has helpful resources for keeping poultry healthy in any operation. Commercial poultry producers can use this toolkit to assess their biosecurity practices and preparedness. 
 
MONITOR FLOCKS: Monitor your flock for clinical signs of HPAI, including monitoring production parameters (feed and water consumption, egg production) and increased morbidity and mortality. Any changes in production parameters that could indicate HPAI should be reported. 
 
REPORT DISEASE: It is important for veterinarians and producers to report any suspicious disease events in poultry flocks to the State Veterinarian’s office at 303-869-9130. If it is after hours, the voicemail message will indicate which veterinarian is on call. 
 
If you have sick birds or birds that have died from unknown causes, help is available at the Colorado Avian Health Call Line at CSU, their number is 970-297-4008. 
 
SECURE FOOD SUPPLY: We also strongly encourage poultry producers to enroll as a Secure Food Supply (SFS) participant through our office. The most important component of ensuring your continuity of business in the face of a HPAI outbreak is to enroll in SFS and have a biosecurity plan in place. If you would like more information on SFS, please reach out to: dave.dice@state.co.us or 303-263-2407.

Bird owners struggling with stress or anxiety around HPAI can contact Colorado Crisis Services by calling 1-844-494-TALK (8255) or texting TALK to 38255. Farmers and ranchers can receive a voucher for six free sessions with an ag-competent provider through the Colorado Agricultural Addiction and Mental Health Program (campforhealth.com). 

 

Emergency Rule Suspending All Colorado Poultry Events

On March 30, the Colorado State Veterinarian advised issuing an emergency rule suspending all poultry shows, including meets, sales, swaps, and competitions. The state’s Agricultural Commission approved this emergency rule. The rule takes effect immediately and will last for 90 days (until June 30, 2022), unless renewed or ended at an earlier date by vote of the Ag Commission and a recommendation of the State Veterinarian.
