Here they eat raw beef (tartare, carpaccio, filet americain), pork (Mett, Zwiebelmett). Hell, even the japanese don't have the patience to wait until their fish is cooked. : -)
There are not very many beef to human deseases. I think the most harmful one is Creutzfeldt Jakob and related BSE. You would need to Cook your steaks very welldone to kill that, as it's mostly in nerves, marrow.
In the past there were more deseases around, aswell as parasites (especially worms in pork), but with modern food standards that's also in the past. Also as mentioned previously, most pathogens originate from cutting the meat, so the vast majority is on the outside. Those where grilled.
So I wouldn't worry to much if you get fresh meat from a respected seller. Poultry and fish are far more dangerous. But agreed, I wouldn't eat it myself (I prefer medium rare).
