How long before mozzarella cheese molds?

The exact amount of time it takes for mozzarella cheese to mold depends on factors such as the storage temperature, humidity level, and the specific strain of bacteria present. However, under normal room temperature conditions, mozzarella cheese typically begins to mold within a few days to a week after being opened and exposed to air. To prevent mold growth, it is best to store mozzarella cheese in an airtight container in the refrigerator and consume it within a week or so of opening.
