If you’re a cheese lover, you know that Parmesan cheese is a must-have ingredient in many dishes. This hard, dry cheese has a distinct flavor and is often grated over pasta, soups, or salads.

However, like any other food product, Parmesan cheese can go bad after some time. But the question is: can you get sick from old Parmesan cheese Let’s find out.

How Does Parmesan Cheese Go Bad

Parmesan cheese is made from unpasteurized cow’s milk and aged for at least 12 months. During the aging process, the cheese loses moisture and becomes hard and dry. This makes it less hospitable to bacteria, which is why it has a longer shelf life than other cheeses.

However, even though Parmesan cheese can last for a long time if stored properly, it can still go bad. The most common signs of spoiled Parmesan cheese are mold growth and changes in texture or color. If you notice any of these signs, it’s best to discard the cheese.

Can You Get Sick From Eating Spoiled Parmesan Cheese

Yes, eating spoiled Parmesan cheese can make you sick. When cheese goes bad, harmful bacteria such as Staphylococcus aureus and Salmonella grow on it. These bacteria can lead to food poisoning or other gastrointestinal issues.

It’s worth noting that not all molds that grow on old cheeses are harmful. Some types of mold are safe to eat and even add flavor to the cheese. However, if you’re not sure whether the mold on your Parmesan cheese is safe or not, it’s best to err on the side of caution and throw it away.

How to Store Parmesan Cheese Properly

To extend the shelf life of your Parmesan cheese and prevent it from going bad prematurely, store it properly. Here are some tips:

1. Keep it refrigerated: Store your Parmesan cheese in the fridge at all times. This will slow down the growth of bacteria and mold.

2. Wrap it tightly: Wrap your Parmesan cheese tightly in plastic wrap or aluminum foil to prevent moisture from getting in and causing mold growth.

3. Don’t freeze it: Freezing Parmesan cheese can cause it to lose its texture and flavor, so it’s best to avoid freezing it if possible.

4. Use a cheese saver: If you eat Parmesan cheese frequently, consider investing in a cheese saver. This is a special container designed to keep cheese fresh for longer by regulating humidity levels.


In conclusion, yes, you can get sick from old Parmesan cheese that has gone bad due to harmful bacteria or mold growth. To prevent this from happening, make sure to store your Parmesan cheese properly and discard any that shows signs of spoilage. By doing so, you can enjoy this delicious cheese without any risk to your health.
