Steak comes from a sterile place: the inner body of an animal. I don't know of any parasites burrowing their way out of the guts upon temperature changes when cows are killed unlike fish which are loaded with parasites. Thus it's pretty safe to eat steak raw from a pathogen perspective unless handling was botched.
