Mold grows on cheese when it is placed in a badly ventilated or moist area. Mold spores are airborne all around us, invisible to the naked eye. And if one spore makes it onto a piece of cheese, it can begin to reproduce rapidly and feed off of the cheese.

The amount of mold that grows on cheese depends on the type of cheese as well. There are soft, semi soft, semi hard or hard cheeses produced, and the softer the cheese, the quicker the chances it can grow mold. Most soft cheeses are more watery, and are also the freshest cheeses, and will facilitate more growth if it comes into contact with mold.
