Chronic wasting disease (CWD) is a highly infectious and fatal neurodegenerative disorder that affects cervids, including deer, elk, and moose. The disease is caused by a misfolded protein called a prion, which can be transmitted through direct contact with infected animals or contaminated environments. As CWD continues to spread across North America, hunters and consumers of wild game meat are growing increasingly concerned about the risks of contracting the disease. One question on everyone’s mind is: can cooking kill chronic wasting disease?
Understanding Chronic Wasting Disease
Before we dive into the cooking question, it’s essential to understand the basics of CWD. The disease was first identified in the 1960s in Colorado and has since spread to over 25 states and several Canadian provinces. CWD is characterized by a long incubation period, often taking years or even decades to manifest symptoms. Infected animals may appear healthy, but they can still transmit the disease to other animals and contaminate their surroundings.
CWD is caused by a prion, a type of protein that can misfold and cause normal proteins to also misfold. This leads to brain damage and eventually death. Prions are highly resistant to heat, chemicals, and other environmental stressors, making them a significant concern for human health.
Transmission Risks
While CWD is primarily a wildlife disease, there is a risk of transmission to humans. The most significant risk factor is consuming infected meat, particularly from animals that are already showing symptoms of the disease. However, even asymptomatic animals can harbor the disease, making it challenging to determine whether meat is safe to eat.
Other transmission risks include:
- Handling infected animals or their tissues
- Exposure to contaminated environments, such as soil or water
- Using contaminated equipment or tools
Can Cooking Kill Chronic Wasting Disease?
Now, let’s address the question on everyone’s mind: can cooking kill chronic wasting disease? The answer is not a simple yes or no.
Cooking can reduce the risk of transmission, but it may not eliminate it entirely. Prions are highly resistant to heat, and research suggests that even high temperatures may not be enough to inactivate them completely.
A study published in the Journal of Infectious Diseases found that cooking meat at 212°F (100°C) for 30 minutes reduced the infectivity of prions by 90%. However, this does not mean that the meat is completely safe to eat. Another study published in the Journal of Food Protection found that cooking meat at 248°F (120°C) for 1 hour reduced the infectivity of prions by 99.9%. However, this level of heat may not be achievable in a typical cooking scenario.
Cooking Methods and Temperatures
Different cooking methods and temperatures can affect the risk of transmission. Here are some general guidelines:
- Grilling or pan-frying: These methods may not be enough to inactivate prions, as the temperatures may not reach high enough levels.
- Roasting or baking: These methods can reach higher temperatures, but the risk of transmission may still exist.
- Boiling or stewing: These methods can reach high temperatures, but the risk of transmission may still exist, especially if the meat is not cooked for a sufficient amount of time.
Temperature Guidelines
To minimize the risk of transmission, it’s essential to follow proper cooking guidelines. Here are some temperature guidelines to keep in mind:
- 212°F (100°C) for 30 minutes: This temperature and cooking time can reduce the infectivity of prions by 90%.
- 248°F (120°C) for 1 hour: This temperature and cooking time can reduce the infectivity of prions by 99.9%.
Other Methods for Reducing Transmission Risk
While cooking can reduce the risk of transmission, it’s essential to consider other methods for minimizing the risk. Here are some additional strategies:
- Test for CWD: If you’re a hunter, consider having your animal tested for CWD. This can help determine whether the meat is safe to eat.
- Handle meat safely: When handling meat, use proper safety protocols, such as wearing gloves and washing your hands thoroughly.
- Avoid eating high-risk tissues: Certain tissues, such as the brain, spinal cord, and lymph nodes, are more likely to harbor prions. Avoid eating these tissues to minimize the risk of transmission.
- Use proper equipment and tools: Use equipment and tools that are specifically designed for handling wild game meat, and make sure they are properly cleaned and sanitized.
Conclusion
While cooking can reduce the risk of transmission, it’s essential to consider other methods for minimizing the risk. By following proper cooking guidelines, handling meat safely, avoiding high-risk tissues, and using proper equipment and tools, you can reduce the risk of contracting chronic wasting disease.
However, it’s essential to remember that there is no foolproof method for eliminating the risk of transmission entirely. If you’re a hunter or consumer of wild game meat, it’s crucial to be aware of the risks and take steps to minimize them.
By being informed and taking the necessary precautions, you can enjoy wild game meat while minimizing the risk of contracting chronic wasting disease.

What is Chronic Wasting Disease?
Chronic Wasting Disease (CWD) is a neurological disorder that affects deer, elk, and moose. It is a type of prion disease, which means that it is caused by an abnormal protein that can be transmitted through contact with infected tissue. CWD is a significant concern for hunters and wildlife managers, as it can have a major impact on deer populations and potentially pose a risk to human health.
CWD is characterized by a range of symptoms, including weight loss, behavioral changes, and difficulty walking. It is a fatal disease, and there is currently no cure or treatment available. CWD has been detected in several states in the US, as well as in Canada and other countries.
Can Cooking Meat Prevent Chronic Wasting Disease?
Cooking meat can help to reduce the risk of transmitting Chronic Wasting Disease (CWD), but it is not a foolproof method. The abnormal prion protein that causes CWD is highly resistant to heat, and it can survive even high temperatures. However, cooking meat to an internal temperature of at least 165°F (74°C) can help to denature the protein and reduce the risk of transmission.
It’s also important to note that cooking meat is just one part of a larger set of precautions that hunters and consumers can take to reduce the risk of CWD transmission. Other steps include handling and processing meat safely, avoiding contact with potentially infected tissue, and having meat tested for CWD before consuming it.
What is the Risk of Getting Chronic Wasting Disease from Eating Infected Meat?
The risk of getting Chronic Wasting Disease (CWD) from eating infected meat is considered to be low, but it is not zero. There have been no documented cases of CWD transmission to humans, but there is still a theoretical risk. The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) have both stated that the risk of CWD transmission to humans is low, but they also recommend taking precautions to minimize the risk.
It’s worth noting that the risk of CWD transmission is likely to be higher for people who handle and consume large quantities of potentially infected meat, such as hunters and their families. However, even for these individuals, the risk is still considered to be relatively low.
How Can Hunters Reduce the Risk of Chronic Wasting Disease Transmission?
Hunters can reduce the risk of Chronic Wasting Disease (CWD) transmission by taking a number of precautions. These include having their meat tested for CWD before consuming it, handling and processing meat safely, and avoiding contact with potentially infected tissue. Hunters should also wear gloves when handling meat, and make sure to clean and disinfect any equipment that comes into contact with the meat.
Hunters can also reduce the risk of CWD transmission by being aware of the areas where CWD has been detected, and taking extra precautions when hunting in those areas. This may include avoiding areas with high CWD prevalence, and being more careful when handling and processing meat.
What are the Symptoms of Chronic Wasting Disease in Humans?
There are no documented cases of Chronic Wasting Disease (CWD) transmission to humans, so the symptoms of CWD in humans are not well understood. However, it is likely that the symptoms would be similar to those of other prion diseases, such as Creutzfeldt-Jakob disease. These symptoms may include memory loss, personality changes, and difficulty with coordination and balance.
It’s worth noting that the symptoms of CWD in humans would likely take many years to develop, and may not appear until long after the initial exposure to the disease. This makes it difficult to diagnose CWD in humans, and highlights the importance of taking precautions to minimize the risk of transmission.
Can Chronic Wasting Disease be Transmitted Through Casual Contact?
Chronic Wasting Disease (CWD) is not typically transmitted through casual contact, such as touching or handling an infected animal. The disease is usually transmitted through direct contact with infected tissue, such as brain or spinal cord tissue. However, it is possible for CWD to be transmitted through contact with contaminated soil or other environmental surfaces.
It’s worth noting that the risk of CWD transmission through casual contact is considered to be low, and most people are not at risk of getting the disease through everyday activities. However, hunters and others who handle potentially infected animals or tissue should take precautions to minimize the risk of transmission.
Is There a Test for Chronic Wasting Disease in Humans?
There is no test for Chronic Wasting Disease (CWD) in humans, and the disease can only be diagnosed after death through an autopsy. However, there are tests available for CWD in animals, and these tests can help to identify infected animals and reduce the risk of transmission.
It’s worth noting that the lack of a test for CWD in humans highlights the importance of taking precautions to minimize the risk of transmission. Hunters and others who handle potentially infected animals or tissue should take steps to reduce their risk of exposure, and should be aware of the areas where CWD has been detected.
