Mold generally can’t penetrate far into hard and semisoft cheeses, such as cheddar, colby, Parmesan and Swiss. So you can cut away the moldy part and eat the rest of the cheese.

As the calcium lactate levels rise they will eventually reach a point where they crystallize and become visible to us as the crystals. These crystals can form on the surface of cheeses where moisture can collect.
