Well, molds have to be different. Good and Bad. A friend had a house with mold in the foundation and cellar. She miscarried a couple of times, her kids quit growing, and her husband was sick. They had to let the bank foreclose, because they couldn't afford the cost of cleaning it (if it was even possible) and couldn't possibly sell it.
all mold is not the same. Hard cheese; the mold gets cut away. Soft cheese and bread, trash. Obviously, cultured mold cheese is fine for most healthy people. Why take a chance? If the mold isn't supposed to be there, toss it. The cost of the loaf of bread is one heck of a lot less than the cost of a visit to your doctor, or heaven forbid, the emergency room.
