What causes CWD?
A misfolded protein known as a prion is responsible for chronic wasting disease. Normal prions are produced by all mammals. Cells use them, and then they are eliminated or recycled within the body. Normal prions can become abnormal when they come in contact with disease-associated prions.
Can humans then get CWD?
Although CWD has not been confirmed in humans, studies have shown that it can be transmitted to other animals, such as primates. According to the CDC, humans should eat infected deer meat to prevent it spreading to them.
What are the signs and symptoms of CWD? Infected animals may experience excessive salivation, muscle coordination problems, difficulty swallowing, excessive thirst and excessive urination. Subtle behavioral changes such as loss of fear or abnormal behavior can be the first sign of infection.
How can you prevent CWD, other than the above?
Prevention
- Rubber gloves or latex gloves are recommended for handling meat and dressing animals.
- Reduce the amount of time you spend on the organs, especially the brain and spinal cord tissues.
- Field dressing should not be done with household knives or any other kitchen utensils.
How can you get chronic wasting diseases?
CWD can be transmitted from animal-to-animal contact and indirectly by contact with infected objects and environments (including saliva, urine and feces) Learn more at the Center for Disease Control (CDC), Chronic Wasting Disease in Animals.

Can CWD kill humans?
CWD is typified by chronic weight loss and clinical signs compatible with brain lesions, aggravated over time, always leading to death. No relationship is known between CWD and any other TSEs of animals or people.
How do you kill prions?
To destroy a prion it must be denatured to the point that it can no longer cause normal proteins to misfold. Sustained heat for several hours at extremely high temperatures (900°F and above) will reliably destroy a prion.
Does cooking kill CWD?
Cooking does not destroy prions, and ingestion of another prion, the agent that causes bovine spongiform encephalopathy (BSE), has been linked to a fatal human neurological disease. CWD prions have been found in muscle (meat), as well as other tissues of cervids, and could enter the food supply.
How do you get prions?
Prion diseases can come about in one of three ways: acquired, genetic or sporadic. Acquired means the person gets exposed to prions and becomes infected. Even though prions are scary, they're very hard to catch, and so infection is the least common way of getting a prion disease.
Are prions alive?
Not only are prions not alive (and contain no DNA), they can survive being boiled, being treated with disinfectants, and can still infect other brains years after they were transferred to a scalpel or other tool.
Can humans get 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. This can happen if you eat nerve tissue (the brain and spinal cord) of cattle that were infected with mad cow disease.
What is the zombie deer virus?
“Zombie deer” disease, also known as chronic wasting disease, is a type of prion disease that affects deer, elk, and moose. Prions are small, abnormal, infectious proteins that cause proteins in the body to fold abnormally, especially in the brain and spinal cord.
How long can prions survive?
Those powers are considerable. According to one account, prions resist digestion by protein-cleaving enzymes, may remain infectious for years when fixed by drying or chemicals, can survive 200°C heat for 1-2 hours, and become glued to stainless steel within minutes. Oh, and they're also resistant to ionizing radiation.
Can humans get CWD from eating deer meat?
CWD is far less prevalent in elk than deer. There is currently no scientific evidence that CWD has or can spread to humans, either through contact with infected animals or by eating meat of infected animals.
What 24 states is the zombie deer disease in?
The disease is always fatal. As of August, the CDC reported infected deer, elk and moose in 227 counties across 24 states, primarily clustered in Wyoming, Colorado and Kansas.
What states is the zombie deer disease in?
Wildlife officials in states including Nevada, Iowa, Wyoming, Pennsylvania and Tennessee have either warned hunters about the disease to prevent its spread to their state or confirmed new cases.
What does prion stand for?
A prion (short for proteinaceous infectious particle) is a unique type of infectious agent, as it is made only of protein.
What does CWD look like inside a deer?
The most obvious sign of CWD is progressive weight loss. Numerous behavioral changes also have been reported, including decreased social interaction, loss of awareness, and loss of fear of humans. Diseased animals also may exhibit increased drinking, urination, and excessive salivation.
Can you burn deer carcass?
Do Not Place in Water: It is illegal to dispose of carcasses or remains in streams, ponds, or other bodies of water. Do Not Burn: Only commercial incinerators reaching over 1,800 degrees Fahrenheit can generate enough heat for long enough to destroy the prions that cause CWD.
Where are the zombie deer?
Chronic wasting disease (CWD) is a prion disease that affects deer, elk, reindeer, sika deer and moose. It has been found in some areas of North America, including Canada and the United States, Norway and South Korea.
What is a CWD zone?
CWD Management Zone. The CWD Management Zone includes counties within 10 miles of confirmed CWD detections. Special regulations apply within these counties, including: Increased surveillance in these counties is important to better understand where the disease is and apply management actions to slow the spread.
Is CWD harmful to dogs?
It is often difficult to diagnose a deer, elk, or moose with CWD based on these symptoms alone because many of CWD symptoms also occur with other diseases and malnutrition. CWD is always fatal. CWD does not appear to naturally infect cattle or other domesticated animals.
