A friend of mine ran into a similar problem with rendering particles
with fog lights.  But in his case the foglight had a very sharp cut off
as if no ramp had been applied (which it had).  He's been able to
reproduce his problem in new files as well.  Seems like there's some
sort of bug in particles and fog lights in the same scene.

Do you get the same results for the particles with no fog lights?

1. particles don't disappear in fog

I was making this underwater scene, trying to do the dust you always
see floating right in front of the camera and I found out that
particles don't disappear in fog! In fact, in a scene I did earlier
the particles even got extremely colorful once they attempted to
disappear in fog.

Now I've tried to do the dust in steamer, but I can't get it right.
I'm pretty stuck on this, and I want that sucker dust floating in
there for sure. Now don't say I put up 20000 tiny spheres in that
scene - I'll go nuts.
