Conversely industrialized meat production is relatively recent, and so the volume of prion's being introduced into the environment is potentially much higher then the rate at which they are degrading naturally, not to mention the degree of regional cross-mixing of sources.
Prion contamination can now be shipped around the world in about 24 hours, where it can enter new populations much more easily.
