skin and rest of products after in this image are starred

as of now, i dont see a way to un-star an animal. some pig long time ago had to be fed something nasty which resulted in cascade of moms feeding babies starred milk. where I find this process fail is that babies are born with full bar of food. mom's food, i'd assume.
yet the balls come out clean, why? if animal is clean before it has chance to eat the food its born with (again, why?), it seems to be clean. yet butchering it results in starred products.
solution 1: make babies born with empty food bar as they should, give us the chance to feed it milk from clean mother.
solution 2: (me dont likey) star the bollocks as well for consistency.
solution 3: (best reasonable option) if baby animal didn't ticked yet the feeding process, allow us to harvest clean materials from it. this is best one imho as to achieve something clean out of my wrecked flock, one needs to be diligent enough catch the 'clean' baby before it feeds, meaning right after being born.
