GRANT COUNTY – The Washington State Department of Agriculture confirmed the first case of highly pathogenic avian influenza, commonly known as bird flu, in Grant County on Oct. 11. The detection was reported in a large commercial poultry facility in Moses Lake. This case acts as a sobering reminder of the ongoing threat that HPAI poses, not only to poultry but also to surrounding wildlife and potentially to humans. 

In 2025, as of Nov. 12, according to the Washington State Department of Agriculture, there were four cases in counties including Snohomish, Grant, Mason and Franklin.  

State veterinarians were first alerted to the presence of sick birds on October 7, prompting intensive testing that ultimately confirmed the HPAI strain H5N1. In response, WSDA veterinarians have urged bird owners throughout Washington to heighten their biosecurity measures to protect their flocks. 

“This first detection of the season is a sobering reminder that highly pathogenic avian influenza remains a threat to all domestic poultry — large or small — statewide,” stated Dr. Amber Itle, Washington State Veterinarian. She emphasized the importance of keeping birds away from wild waterfowl, limiting access to poultry flocks, and ensuring species separation as effective strategies to mitigate the risks associated with this disease. 

Individuals residing within a six-mile radius of the confirmed case are placed in a surveillance zone and are encouraged to monitor the health of their flocks, with WSDA recommending the use of an online self-reporting tool to facilitate efficient communication with veterinarians. 

Lexi Smith, Public Information Officer for Grant County Health District, expressed concern about the implications of HPAI for local residents. 

“While the risk to humans is still considered low, there are steps you should take to keep you and your family safe,” she said.  

Smith outlined that those with job-related or recreational exposure to infected birds are at a heightened risk and should exercise caution. 

As hunting season approaches, Smith highlighted the necessity of preventing contact with wild birds, advising, “If you notice any ill or dead wildlife, don’t handle it. Don’t let your dog retrieve it.”  

She pointed out that wildlife can be asymptomatic, making it essential for the public to be vigilant without direct physical contact. 

Backyard poultry owners, who account for approximately 95% of all domestic animal detections in Washington State, are particularly encouraged to strengthen their biosecurity measures. Smith advised flock owners to keep their birds contained within covered runs, monitor feed storage closely, and minimize visitors to poultry enclosures.  

“There are biosecurity protocols put in place by WSDA to help protect these flocks,” Smith said.  

She urged owners to remain attentive for signs of avian influenza, explaining that monitoring and self-reporting can significantly contribute to both public health and the safety of local poultry. 

The risk of human infection due to HPAI is primarily dependent on direct or prolonged contact with infected birds or environments.  

“People can get infected if the virus gets into a person’s eyes, nose, or mouth, or if it is breathed in,” Smith said. 

Although there have been over 70 confirmed human cases of avian influenza reported nationwide since early 2024, with one confirmed death, there has been no evidence of human-to-human transmission in the United States. Nonetheless, the GCHD is closely monitoring the situation, particularly amongst those with direct exposure to infected environments. 

To further protect themselves, Smith advised the community to maintain good hygiene practices—specifically through frequent handwashing and thorough cooking of poultry products. High-risk groups, including dairy workers and veterinary staff, can contact GCHD to discuss the availability of personal protective equipment to mitigate exposure risks. 

In the wake of the confirmed bird flu case, the WSDA emphasized the importance of reporting suspected cases or unusual health signs in both domestic and wild birds.  

Smith reinforced this point, saying, “If you find any birds that seem unwell, report them to the WSDA. It’s vital for ensuring we can contain the spread.”
