You do get parasites in the meat too, Beef is lower risk, Pork is higher risk but still I prefer not to take it.
The butcher telling me Farmer Bloggs provided the cow is neither here nor there I'm too removed from the animal welfare to judge for myself.
I also find meat cooked so the flesh is cooked and the juices are on the turn is the most enjoyable outcome flavourwise. I don't mind other people thinking different.
