For the first time, Washington's Spokane County has logged a confirmed case of chronic wasting disease (CWD) in a white-tailed deer. According to the Washington Department of Fish and Wildlife (WDFW), a deceased adult female deer in the Fairwood area prompted the discovery of this contagious neurological ailment, which is akin to other prion diseases and bears fatal consequences for affected wildlife. With no current cure, CWD poses a significant threat to deer populations as the malady can only be confirmed through postmortem analysis of an animal's lymph nodes or brain tissue.
This particular case sprung up during an enhanced surveillance effort by the WDFW that started in 2021, given the disease's presence in nearby western Montana. "With the spread of CWD across the country and recent detections in adjacent states and provinces, WDFW has proactively conducted surveillance in this area since 2021," Eric Gardner, WDFW’s Wildlife Program Director, said in a statement obtained by WDFW. Hassan intricate Chronic Wasting Disease Management Plan is in place to guide the Department's next steps in curtailing the disease's advance.
While there are no cases of CWD leaping to domestic animals or other ungulate species, and furthermore no evidence of human transmission as supported by recent NIH research, the existence of this first case in Washington state has spurred WDFW to prepare for widespread tissue sample collection from local deer, elk, and moose. The public is encouraged to assist by reporting sightings of ill-appearing cervids and abstaining from feeding wildlife. Such behaviors can escalate the spread of diseases by congregating animals.
The CDC has issued advisories against consuming meat from animals infected with CWD. Hunters in the region are urged to be particularly vigilant this season, with testing and carcass transportation regulations slated for updates. Details on these measures and further information concerning CWD can be found on the WDFW website.
Collaborative efforts are underway as WDFW joins forces with landowners, state and local governments, tribal entities, and wildlife stakeholders to confront this environmental health challenge. More information will be disseminated during a virtual media briefing scheduled for August 5, where WDFW science and veterinary staff will be joined by colleagues from the Department of Health and Department of Agriculture.
