Chronic Wasting Disease Monitoring

Idaho Fish and Game has tested lymph nodes from deer since 1997 looking for CWD in Idaho’s wildlife. CWD has not been detected in Idaho, but it is present in states bordering Idaho.

Testing samples from deer is the first line of defense in monitoring Idaho’s wildlife for CWD and hunters play a vital role in this effort.

How Hunters Help Monitor for CWD

Fish and Game biologists collect lymph nodes as samples from harvested and salvaged animals in specific game units. This is done at check stations, regional offices, and other regional drop-off locations.

If you harvest a deer in one of the CWD priority sample areas, here’s what you can to do to help:

Do It Yourself

You can help our efforts by collecting the lymph nodes yourself. Follow our "How-to" guide and find a drop-off location or mail-in the sample.

Check Station

Stop at a check station with your harvested deer. Fish and Game staff will help retrieve the lymph nodes from your animal.

Regional Offices

Bring your harvested deer head to a Regional Office, where Fish and Game staff will help retrieve the lymph nodes from your animal. Hunters may want to call ahead to ensure someone is available to sample their deer.

Please leave the upper portion of the neck attached to the head so that staff can remove the lymph nodes from the throat. Only adults and yearlings, no fawns.

Salvaged Roadkill

Individuals who salvaged road-killed deer in the Priority Areas are asked to voluntarily bring in the head and upper neck to a regional office or CWD sample drop-off location for lymph node removal.

Is your hunt unit being sampled for CWD?

Wildlife managers adjust the big game units selected for CWD sampling every year. You can find the areas for the current year by clicking on this map.
