spray it with bleach and keep that area moisture free....i saw a show where this guy became severely ill from some rare bread mold...the poor guy lost most of his face...his eyes and nose were gone...i felt so bad for him..it was terrible. i don't think mold would fall into the carcinogen category...mold can cause a lot of issues but i highly doubt that it can cause cancer.
