Well this is certainly very interesting and filled with all sorts of topics of relevance to microbiology of the built environment: Source: Did a moldy building kill 4 New Orleans college professors? | NOLA.com.
I am by no means a mold expert so I am not sure I can comment much on the debate here and who is right or wrong.

Definitely worth a look.
