Short answer - nothing that will infect your beer will harm you to drink it. Tasty nasty 95%+ of the time yes (so maybe harm your tastebuds for a few minutes) but nothing will harm you.
With modern methods of getting the food to you, there is nothing that you should infect your beer with that will be hazardous. While some might suggest a mutant streptococal or some nasty could live in wort, how would it get there? do you play at the CDC by day and forget to observe proper protocol and make beer as a hobby? "Can infected beer kill me" gets to be a great SciFi movie, but the reality is, to get a litterally 'killer beer' there would have to be some serious intent (Cue a Revvy post about this).
So again, no infected beer can't harm you, beyond what harms your tastebuds endure.
