Here are some quotes from various medical sources:
"CWD is similar to “mad cow disease” in cattle, scrapie in sheep, and Creutzfeldt-Jakob disease (CJD) in humans."
"Is Creutzfeldt-Jakob disease the same as mad cow?
CJD is not the same as mad cow disease or CWD. All three diseases are in the TSE family and can cause related illnesses and brain lesions. However, they are caused by three different prions that can be differentiated from one another in a laboratory."
"What happens if a human eats beef with mad cow disease?
People cannot get mad cow disease. But in rare cases they may get a human form of mad cow disease called variant Creutzfeldt-Jakob disease (vCJD), which is fatal. Over time, vCJD destroys the brain and spinal cord."
"Has a human ever gotten mad cow disease?
One case has now been detected in the United States. Strong evidence indicates that BSE has been transmitted to humans through the consumption of BSE-tainted beef and beef products, causing a human form of the disease known as variant Creutzfeldt-Jakob disease (vCJD), which is a rare, fatal brain disorder."
"Does CWD infect people?
There is no direct evidence that CWD has ever been transmitted to humans like mad cow disease (as vCJD). However, some research shows that CWD can be transmitted to monkeys closely related to humans by feeding them meat or brain tissue from deer and elk infected with CWD. Because of this, health organizations like the Centers for Disease Control and Prevention suggest being careful if you eat meat from animals harvested from areas where CWD has been found."
The majority of sources about CWD I have read, since it was first detected no more than 50 miles from my home in Minnesota and within a few miles of a place I hunted, agree mad cow has transmitted to humans as a variant and monkeys have gotten CWD from being fed contaminated deer/elk meat. To me it's not a great leap to assume that CWD, being from the same family of TSEs and considering mad cow transfer & mutation to vJCD in humans and/or monkeys getting CWD directly, that there is some level of risk to eating meat from a deer known to be CWD positive.
I am now in a full fledged CWD area as it has slowly spread across SE MN and is now also in Central MN, albeit at VERY low test counts. Everyone can have their deer kill tested to be sure. Testing in Minnesota is mandatory the first two days of each modern gun season.
The MN DNR's position on eating an infected deer simply refers to the CDC's position:
"...public health officials at the Centers for Disease Control and Prevention (CDC) recommend that hunters do not consume meat from animals known to be infected."
