Well, I don't know where you live, but we live in California and just had a flood on Friday afternoon. We were at a Healing Arts Festival on Sunday afternoon and I saw a bunch of pamphlets. One of interest to me (due to the flood) is called "Mold in My Home: What Do I Do?" and it is from the California Department of Health Services and is an Indoor Air Quality Info Sheet.
It is four pages front and back, so I cannot retype it all for you. I will give you some of the highlights in hopes it helps you in some way.

"Molds are simple, microscopic organisms, present virtually everywhere, indoors and outdoors."
"Everyone is exposed to some mold on a daily basis without evident harm."
"If indoor mold contamination is extensive, it can cause very high and persistent airborne spore exposures."
"Evidence of past or ongoing water damage should trigger more thorough inspection. You may find mold growth underneath water-damaged surfaces or behind walls, floors, or ceilings."
I'll paraphrase the testing section since it is VERY long and detailed with no one succinct quote. Testing is inaccurate because there are so many types of molds inside and outside and everyone is affected differently by differing amounts.
Clean-up Procedures:
identify and eliminate sources of moisture
identify and assess the magnitude and area of mold contamination
clean and dry moldy area - use containment of affected areas
bag & dispose of all material that may have moldy residues, such as rags, paper, leaves, and debris
The rest of the clean-up is LENGTHY, so I'll paraphrase again.
WEAR A RESPIRATOR (N-95), but it will not protect you from fumes.
Wear protective clothing and gloves, etc that can be discarded or easily cleaned.
Try cleaning a test area first and see how it affects you.
Have everyone (esp children and elderly) leave the area while you clean.
IF you are adversely affected (or others are), hire a professional.
Generally, areas 10 square feet or less are handled by the homeowner and areas more than 100 square feet are best handled by a professional. In between is a judgement call.
Remove moldy items first in bags and dispose in trash. If sheetrock (or drywall) was wet, then remove from ABOVE the highest watermark down. Toss porous items such as paper, rags, wallboard, rotten wood, carpet, drapes, and upholstered furniture. Solid materials , such as glass, plastic, metal, can usually be cleaned and kept.
Then dry affected areas for 2-3 days.
Clean with soap or detergent in HOT water and scrub entire affected area. Use stiff brush or cleaning pad on uneven surfaces.
Rinse cleaned items with water and dry thoroughly. A wet/dry vacuum is helpful.
THEN, disinfect. Bleach is the only disinfectant specifically mentioned and the pamphlet makes it clear it is MORE useful when diluted than when used straight. A 10% solution is recommended and it is also recommended to leave it on for 10 minutes prior to rinsing and drying.
DO NOT USE A FAN until all the mold is gone or you simply send the spores flying all over your home.
