Have you ever wondered if Parmesan cheese can mold? It’s a valid question, especially considering that mold can grow on many types of food. In this article, we’ll explore whether or not Parmesan cheese is susceptible to mold and what you can do to prevent it.

What is Parmesan Cheese?

Before we dive into the topic, let’s first understand what Parmesan cheese is. Parmesan cheese, also known as Parmigiano-Reggiano, is a hard Italian cheese made from cow’s milk. It has a sharp and nutty flavor, making it a favorite among cheese lovers around the world.

Does Parmesan Cheese Mold?

Contrary to popular belief, Parmesan cheese is highly resistant to mold. This is due to its low moisture content and aging process. The production of Parmesan cheese involves removing most of the whey during the cheesemaking process and then aging it for an extended period.

Low Moisture Content:

The low moisture content of Parmesan cheese prevents the growth of mold. Mold needs moisture to thrive, and without it, it cannot survive. This characteristic makes Parmesan cheese less likely to spoil compared to other types of cheeses with higher moisture content.

Aging Process:

The aging process further enhances the resistance of Parmesan cheese to mold. During aging, the cheese wheels are carefully stored in temperature-controlled rooms for an extended period, typically between 12 and 36 months. This extended aging time creates an inhospitable environment for mold growth.

Preventing Mold on Parmesan Cheese

While the chances of finding mold on your block of Parmesan are relatively low, it’s still important to take precautions to prevent mold growth.

Proper Storage:

To keep your Parmesan cheese fresh and mold-free, it’s crucial to store it properly. Wrap the cheese tightly in wax paper or aluminum foil to protect it from air and moisture.

Then, place it in an airtight container or resealable bag. Store the cheese in the refrigerator at a temperature between 35°F and 40°F.

Avoid Cross Contamination:

When handling Parmesan cheese, make sure your hands are clean to avoid introducing any potential mold spores. Additionally, use clean utensils when cutting or grating the cheese to prevent cross-contamination with other molds or bacteria.


In conclusion, Parmesan cheese is highly resistant to mold due to its low moisture content and aging process. While it’s unlikely for Parmesan cheese to develop mold, proper storage and handling are essential to prevent any potential spoilage. By following these guidelines, you can enjoy your Parmesan cheese worry-free for an extended period.

Now that you know more about the resistance of Parmesan cheese to mold, you can confidently add this delicious cheese to your favorite dishes without worrying about spoilage!
