I had researched on prions and the Kuru disease for a class while looking at the impacts of animal testing (the Kuru disease is a prion found in New Guinea and is considered to be the first prion disease). Prions are scarily dangerous - near-fatal if exposed to it, and stable at much higher temperatures that regular non-misfolded proteins.
However, your chances of getting prions is very low. As long as you avoid "exotic" meat like monkey brains and stay in countries with strong regulatory bodies (like the US/EU etc) the risk of exposure is extremely limited. Bonus points if you avoid swimming in random bodies of water to not get contaminated water with brain-eating amoeba traveling up your nose.
