Moldy trash bag (2weeks old) sat in front of fan on high. blew for 35-40 minutes and i breathed it in the entire time w/o knowing. what should i do?

Remove it: You are exposed to mold every time you go outside. It grows on trees/in the soil, on buildings, etc. You are frequently exposed passively in your environment. Very few of the thousands of different molds are toxic to humans. The solution to your problem is a simple one, just remove the item. If any problems arise you would know it over several days.The issue is more urban myth than real.
