I thought that recycling animal waste into the food chain was one of the suspected causes of CJD.

e.g. http://rense.com/general10/MDSS.HTM

It seems like a bad idea to me... (primarily from the unknowns, not the knowns)

It's not every kind of animal waste - it's only waste containing neuronal proteins, like the spine, the brain.

So it was banned.
