Yes I think the type we’re referencing is vCJD, originating from BSE (mad cow disease), I think it was mostly a British thing. I’m pretty sure the origins were feeding processed and infected beef and bone to cattle, giving them ‘mad cow disease’, which when fed to people could cause Jacobs’s. That’s why you don’t see any British beef or dairy anywhere outside of the isles, no one trusts it anymore, though there have been no cases in people for many years.
That’s also one reason why British farming regulations are so strict, for example it is now illegal to feed any animal product to any livestock intended for human consumption, including eggs and dairy. You can’t even feed mealworms to chickens.
The common theme is neurologically Ill livestock, so that’s why I think eating sick birds should be avoided. Actually, as I write this I become more against the idea of eating any ill bird.
