Carcass disposal recommendations

Chronic wasting disease (CWD) can be spread among deer by both direct contact between animals and exposure to environments contaminated with CWD prions, the protein that causes the disease. Exposure to an area where a CWD-positive carcass has decomposed could be enough to cause infection in deer. Because of this risk, it is important that the carcasses of deer possibly infected with CWD, including all bones and other waste from butchering, be disposed of in a way that protects uninfected deer from exposure.

  • The preferred option is disposal in a landfill that accepts deer waste.
  • A second option is to bury the carcass waste deep enough to prevent scavengers from digging it up.
  • As a third option the DNR provides three dumpsters in which hunters can dispose of their carcass waste and whole carcasses from sick deer.
  • As a last resort hunters can put the waste back on the landscape as close to where the deer was harvested as possible.

Landfills are a safe and cost-effective option for disposing of carcass waste from deer potentially infected with CWD. Landfill disposal establishes a barrier between uninfected deer and deer-carcass waste that potentially contains infectious CWD material. Scientific research has shown that when properly disposed of in a landfill, prions are extremely unlikely to migrate from the landfill disposal site. There are disposal methods that destroy prions, such as incineration at 1800 degrees Fahrenheit or digestion in sodium hydroxide, but these methods are cost-prohibitive and not practical for the public.

Sick deer guidance

If a person sees a sick deer the DNR is interested in testing the deer for CWD and can help the individual dispose of the carcass if shot. Please view the sick deer guidance for additional information.
