Chronic Wasting Disease Monitoring

Idaho Fish and Game has tested lymph nodes from mule deer since 1997 looking for signs of 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 from harvested and salvaged animals in specific game units. This is done at check stations and regional offices.

If you harvest a mule deer in one of the game units where samples are being sampled, here’s what you can to do to help:

Check Station:

When you stop at a check station with a harvested deer or elk, Fish and Game staff will help retrieve the lymph nodes from your animal.

Regional Offices:

Fish and Game is asking hunters to voluntarily bring their mule deer heads to a regional office during normal business hours for sampling. 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 mule deer in the sample areas are asked to voluntarily bring in the head and upper neck to a regional office 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.
