Does Parmesan Cheese Go Bad?

Yes, like all types of cheese, parmesan cheese can go bad. While parmesan is a hard cheese that is known for its long shelf life, it is not immune to spoilage.

Factors That Affect The Shelf Life Of Parmesan Cheese

There are several factors that can affect the shelf life of parmesan cheese:

Storage Temperature

Parmesan cheese should be stored in the refrigerator, where the temperature is between 32°F and 41°F. If the cheese is stored at a higher temperature, it will spoil more quickly.

Humidity Level

Parmesan cheese should be stored in a dry place with low humidity to prevent spoilage. High humidity can cause the cheese to become moldy or to develop an off-flavor.


Parmesan cheese is typically sold in vacuum-sealed packaging, which helps to preserve its freshness. If the packaging is damaged or not properly sealed, the cheese may spoil more quickly.

Use-By Date

 Most parmesan cheese will come with a use-by date on the packaging. This date indicates the point at which the cheese is no longer considered fresh and should be used or discarded.


Proper handling of parmesan cheese is important to ensure its longevity. You should always use a clean, dry utensil to remove the cheese from the packaging and avoid leaving the cheese out at room temperature for extended periods of time.

How To Know If Grated Parmesan Cheese Is Bad?

There are a few signs that grated parmesan cheese may have gone bad:

  1. Off-Flavor: If the cheese has an unpleasant or sour smell or taste, it has likely gone bad.
  2. Mold: If you see any mold on the cheese, it has gone bad and should be discarded.
  3. Texture: If the cheese has become hard, crumbly, or dry, it may no longer be fresh and should be discarded.
  4. Color: If the cheese has changed color, such as becoming yellow or brown, it may no longer be fresh and should be discarded.

It’s important to note that these signs do not necessarily mean that the cheese is unsafe to eat. However, if you notice any of these changes in your grated parmesan cheese, it is best to err on the side of caution and discard the cheese.

How Long Can Parmesan Cheese Last In The Fridge?

Parmesan cheese can last for several months in the refrigerator if stored properly. The exact shelf life of parmesan cheese will depend on the specific type of cheese and the storage conditions. Harder, aged parmesan cheese will generally have a longer shelf life than softer, fresher varieties.

To help ensure that your parmesan cheese stays fresh for as long as possible, it is important to store it in the refrigerator at a temperature between 32°F and 41°F.

You should also store the cheese in an airtight container or wrap it tightly in plastic to prevent it from drying. It’s also a good idea to store the cheese in a dry place with low humidity to prevent spoilage.

Is It Ok To Eat Expired Parmesan Cheese?

It is generally not recommended to eat expired parmesan cheese. While hard, aged cheese like parmesan may have a longer shelf life than softer varieties, it is still perishable and can go bad over time. If the cheese has reached its expiration date or has been stored improperly, it may no longer be safe to eat.

Expired parmesan cheese may have an off-flavor, a sour smell, or visible signs of spoilage, such as mold. Consuming spoiled cheese can cause food poisoning, which can lead to symptoms like nausea, vomiting, and diarrhea. In some cases, consuming spoiled cheese can also cause more serious health issues, such as listeriosis.


It is a good idea to use your parmesan cheese within a reasonable time frame and to discard it if it has expired or shows signs of spoilage. Following these guidelines can help ensure that your parmesan cheese stays fresh and enjoyable to eat.
