Iluviaporos - I agree that bone meal should not be fed to animals for the most part, although part of the reason the disease spread was that they weren't disinfecting the bonemeal enough.
But, the fact that they produce bone meal from abattoirs is a very good thing. Otherwise the waste from slaughtering animals would no doubt be put into landfill, or somewhere worse.
This way it gets spread into gardens, or fed to chickens (who are omnivores and should only benefit from the extra calcium) and becomes part of a more natural ecosystem.
Bone meal fertilizer is also a natural way to help your garden flourish and easy access to something which doesn't contain chemicals can only be a good thing for gardeners and the people who eat their produce.
