I guess this is an organic chemical. But, if I decided to clean the rotten dirty floor of an old mobile home with bleach, could that produce a sufficient amount of chloroform that is toxic? I don't know how "trigger happy" the haloform reaction is with organic material.

Nah, I doubt that would happen.  You usually need a lot of X-X to get the haloform reaction to go, plus you need some reasonably strong base like NaOH.  Bleach is pretty much neutral, I think.  You're more likely to suffer from exposure to Cl-Cl than chloroform, I would think.
