Concerns about Mad Cow Disease?
Hello doctor: A few days ago, my family made soup with beef bones, and I had some as well.
Now I'm very worried about contracting mad cow disease.
Is it possible to get infected this way?

Dr. Huang Litong reply Rare Disease
The likelihood of contracting mad cow disease from eating beef is quite low, and the risk is even lower when consuming broth.
It is important to consider the source of the beef bones, particularly if they come from an outbreak area.
If there are any concerns, it would typically take 10 to 20 years for issues to arise, so there is no need for excessive worry.

More Info
Mad Cow Disease, formally known as Bovine Spongiform Encephalopathy (BSE), is a neurodegenerative disease that affects cattle and can be transmitted to humans through the consumption of infected beef products. The human variant of this disease is known as Variant Creutzfeldt-Jakob Disease (vCJD). Your concern about consuming bone broth made from beef bones is understandable, especially given the serious nature of BSE and its potential consequences.
To address your question directly: the risk of contracting Mad Cow Disease from eating bone broth is extremely low, particularly if the beef used comes from a country with strict regulations regarding BSE. In the United States, for example, the USDA has implemented rigorous measures to prevent BSE from entering the food supply. These measures include banning the use of certain high-risk materials (like the brain and spinal cord of cattle) in food products and conducting regular inspections of cattle herds.
When it comes to bone broth, the primary concern would be if the bones used were sourced from cattle that were infected with BSE. However, the risk of infection is significantly reduced if the beef comes from healthy animals and reputable suppliers. Additionally, cooking methods, including boiling bones to make broth, do not eliminate the prions responsible for BSE, but the likelihood of consuming infected material is very low if proper sourcing is followed.
Here are some additional points to consider regarding BSE and bone broth:
1. Source of the Bones: Always ensure that the bones you use for broth come from reputable sources. If you are purchasing beef from a grocery store, look for labels indicating that the beef is from BSE-free regions or certified suppliers.
2. Regulations and Testing: Many countries have strict regulations and testing protocols in place to monitor and control BSE. In the U.S., for example, cattle over a certain age are tested for BSE, and any cattle that show signs of the disease are not allowed to enter the food supply.
3. Symptoms of vCJD: If you are concerned about BSE, it may be helpful to familiarize yourself with the symptoms of vCJD, which can include psychiatric symptoms, sensory disturbances, and progressive neurological decline. However, it is important to note that vCJD is extremely rare.
4. Consulting Healthcare Professionals: If you have ongoing concerns about your health or potential exposure to BSE, it is advisable to consult with a healthcare professional. They can provide personalized advice and reassurance based on your specific situation.
5. General Dietary Practices: Maintaining a balanced diet and being mindful of the sources of your food can help mitigate risks associated with various foodborne illnesses, including BSE. It’s always a good practice to be informed about where your food comes from and the safety measures in place.
In summary, while your concern about Mad Cow Disease is valid, the risk associated with consuming bone broth made from beef bones is very low, especially if sourced properly. If you continue to have concerns, consider discussing them with a healthcare provider who can offer further guidance and reassurance.
