Troubling news coming out of wildlife disease research


Most deer hunters are familiar with chronic wasting disease (CWD). Now there is something new to worry about. CWD is a type of brain-damaging disease known to be a transmissible spongiform encephalopathy (TSE) or prion disease in deer, elk and moose.

There are three other TSE diseases that make the news occasionally:

» Mad cow disease, or bovine spongiform encephalopathy (BSE) in cattle

» Scrapie in sheep

» Creutzfeldt-Jakob disease (CJD) in humans

Humans are not susceptible to sheep scrapie, but BSE did infect about 200 people in Europe in the 1990s. Those findings provided the rationale for a current CWD study being conducted in Canada. This particular study started in 2003.

Macaque monkeys contracted chronic wasting disease after eating meat from CWD-positive deer, according to Canadian researchers. These monkeys where fed infected venison over a three year period.

The quantity of meat fed to the monkeys equates to a human eating a 7-ounce steak per. That is not much venison, and I eat far more than that when I have venison in my freezer.

Three of the five macaques in the study that were eating venison contracted the disease. This finding is the first scientifically documented transmissions of CWD to a primate eating diseased venison.

Because the macaque has a genome very close to that of a human, the results have heightened concerns of human susceptibility to CWD. Researchers and health officials have long wanted to know more about the potential for interspecies CWD transmission.

According to the Alliance for Public Wildlife, a Canadian-based wildlife conservation organization, hunting families in North America eat between 7,000 and 15,000 CWD-infected animals every year. No cases of CWD transmission have been documented.

“This study does not mean people will get CWD,” said Dave Clausen, a Wisconsin veterinarian, deer hunter and former chairman of the Wisconsin Natural Resources Board. “But it means people need to be considering that possibility.”

Another test group of monkeys had CWD infected venison rubbed on their skin did not contract the disease, so it appears that simply coming in contact with infected venison offers a very low risk to a hunter.

The World Health Organization, the federal Center for Disease Control and many state wildlife agencies recommend that hunters do not eat the eyes, brain, spinal cord, spleen, tonsils or lymph nodes of any deer. It is also recommended that wear rubber or latex gloves when field-dressing carcasses, and to bone out the meat from the animal as an extra caution.

I’m sure we will be hearing more about this in the future. Nebraska hunters can visit the Nebraska Game and Parks Commission website and read more about this CWD study and the extra precautions and testing that Game and Parks has implemented for the 2017 deer seasons.
