So beef carpaccio, or steak tartar are perfectly Kosher. Exception are Ethiopian Jews who traditionally don't eat popular Ethiopian raw meat dishes.
IMO if something can't be eaten raw - it's best to be avoided in any form.
Some foods are changed by cooking. For example, kidney beans must never be eaten raw, but are tasy and nutritious cooked.
The only exceptions are: coffee beans for espresso and cocoa beans for dark chocolate ;)
