I am not an expert on mold but the phrase *toxic* mold was invented by lawyers and passed on to the media. I've heard the horror stories here in Sacramento about sick people. The majority of these homes are ready for demolition anyway and are unkept and filthy, usually rentals. Could the fault be in the housekeeping, I don't know....
I don't know about that, but many of mold's mycotoxins and endotoxins are toxic.
