Raw brain? Prions - Creutzfeldt-Jakob disease (CJD)

I just learned from Weam Breiche the following on eating raw brains, which makes me feel quite concerned about trying raw cow brains now, Do you have any thoughts?

R"aw brain (& Spines) - Be careful with where you are sourcing it from; PRIONS are real and are not even destroyed by cooking it, and when they get into your body, they change your DNA, and it can be deadly; it is mad cow disease.

This will result in Creutzfeldt-Jakob disease (CJD), which is caused by abnormal infectious proteins known as prions. These misfolded prion proteins accumulate in the brain, leading to brain damage and the symptoms associated with the disease."
