A black hole massing equivalent to the entire plasma stream at CERN would probably be smaller than the Planck length in diameter.

It would be like firing a marble through the milky way and expecting to hit a planet.
On the other hand, I heard a 'serious scientist' discussing the issue on R4 and it seems some well-informed physicists do have concerns, so...?
(Please excuse imprecision: I haven't specified whether, by black hole, I mean the singularity, or the event horizon. The singularity, of course, has no 'size' at all.)
