Im not allowed to donate blood in N. America because I once lived in the EU for a few years.
Why?
Because feeding cows cows wasn't proved unsafe and therefore allowed in the food chain. Then people started dying. Oopsie.
But it's OK. It better to ask for forgiveness than permission.
That restriction on blood donation due to Creutzfeldt-Jakob disease was lifted in 2022. You should go donate blood.

At the time we didn't know prion disease could be transferred between species. There's no evidence that scrapie (sheep prion disease) or CWD (deer and moose prion disease) can be transmitted to other species. BSE is seemingly a unique prion disease that can affect other mammals.
