Yep. They build up in your body your whole life, but chances are they won't reach a dangerous level before you die. If you start eating human nervous tissue on the other hand you might be in trouble. Same goes for nervous tissue from animals which have a partially carnivorous diet, such as cattle being fed beef offal. That's how BSE happened.
"Avoid eating the central-nervous-system tissue of cows. Focus your beef consumption on normal muscle meat rather than organ meats, such as offal. In particular, avoid eating parts of the central nervous system, such as the brain, spinal cord, retinas, and tonsils.[10] Especially avoid eating these parts in cattle 30 months and older, as this is typically the age group affected by BSE.[11] Eating regular muscle meat and consuming milk poses almost no vCJD risk."
Tonsils are of the central nervous system? Anyway, I am sufficiently agitated now over the matter.
