Mozzarella cheese is a popular type of cheese that is widely used in various dishes, including pizza, lasagna, and salads. It has a creamy texture and a mild flavor that makes it a favorite among cheese lovers.

However, like any other food item, mozzarella cheese also comes with an expiration date. The big question is – Is mozzarella cheese good after the best by date?

What is the Best-by Date?

The best-by date is the date when the manufacturer recommends using the product for the best quality and taste. It does not indicate when the product will spoil or become unsafe to eat.

Factors Affecting Mozzarella Cheese

The shelf life of mozzarella cheese depends on various factors such as storage conditions, type of packaging, and whether it’s opened or unopened.

Storage Conditions: Mozzarella cheese should be stored in a cool and dry place away from direct sunlight. It should be kept in its original packaging until ready to use.

Type of Packaging: The packaging of mozzarella cheese plays an important role in its shelf life. Vacuum-sealed packaging can help extend the shelf life of mozzarella cheese compared to non-vacuum-sealed packaging.

Opened vs Unopened: Once you open the package of mozzarella cheese, its shelf life decreases significantly. The exposure to air can cause moisture loss and increase the risk of mold growth.

How to Tell If Mozzarella Cheese Has Gone Bad?

If you’re wondering if your mozzarella cheese has gone bad after the best-by date, here are some signs to look out for:

  • The texture becomes slimy or sticky.
  • The color turns yellowish or brownish.
  • The smell is sour or rancid.
  • Mold growth appears on the surface of the cheese.

If you notice any of these signs, it’s best to discard the cheese.

Can You Still Eat Mozzarella Cheese After the Best-by Date?

The answer is not straightforward. While mozzarella cheese can still be safe to eat after the best-by date, it’s not recommended. The quality and taste may have deteriorated, and there is a higher risk of foodborne illness due to bacterial growth.

If you’re unsure whether your mozzarella cheese is still good after the best-by date, it’s better to err on the side of caution and discard it.


In conclusion, mozzarella cheese does have a best-by date, but it’s not an expiration date. While you may still be able to eat mozzarella cheese after the best-by date, it’s not recommended. Always check for signs of spoilage before consuming any food item past its recommended shelf life.
