What foods do moulds grow the fastest?

the more moisture a food has and the more time it spends outside a refrigerator or freezer, the faster it is going to spoil, though not necessarily from mold. Wrappers will give protection from heat and fairly good protection from bacteria, vermin, etc, but only temporarily before natural spoilage occurs. Thus, fresh fruits and vegetables, dairy products, etc, will spoil much faster than would dry goods, such as crackers, dehydrated foods, raisins, and so on, under similar conditions
