Also, when anyone begins to store it, then its quality will deteriorate over time.

Therefore while having old found mozzarella cheese, one should look for bad signs to avoid consumption of bad cheese.

What is Mozzarella Cheese?

This is a sliceable curd cheese that originated in Italy.

Back then, it was made with the milk of water buffalo, but now they are made with cow’s milk.

The texture of the cheese is semisoft, and unlike other cheese, mozzarella cheese does not need an aging process.

The price of this cheese varies from manufacturer to manufacturer and depends on the variety of cheese you have.

This is considered the best and healthiest cheese among the others because of its nutritional value.

Mozzarella cheese is regarded as a great source of vitamin B7, also known as biotin.

How Long Does Mozzarella Cheese last? Does Mozzarella Cheese Go Bad?

You have noticed that the cheese does not serve for the same period every time you store it.

That happens because storage conditions are a significant factor affecting mozzarella cheese’s shelf life.

So if anyone wants the cheese to last longer without degrading its quality, then they need to keep its storage up to the mark.

If you have an unopened pack of fresh mozzarella cheese, then you can expect it to last a week longer than its best-by date.

Best by date is just an estimation provided by the producers until they feel their products will offer their best quality.

However, once the product crosses this date, then you need to compromise the taste, but with suitable storing measures, you can retain its authentic taste and flavor even after the best-by date.

For an opened bag, the shelf life will range from 3 to 7 days beyond the best-by date.

The usual best-by date of fresh mozzarella cheese is about 3 to four weeks which is short compared to other cheese variations.

How to Tell if Mozzarella Cheese Has Gone Bad?

  • Moldy Surface

Mozzarella cheese needs to be soaked or dipped in water; otherwise, there are higher chances of getting bacteria.

At the time of storage, if you keep it open, then the areas that come in contact with air will develop bacteria.

These bacterial infections further form moldy or spots on the surface of the cheese.

Mold is basically a cluster of bacteria; thus, if your cheese has become moldy, you should avoid its consumption.

  • Sour Smell

No one can resist the milky aroma of fresh mozzarella; thus, you can sniff the cheese to examine its freshness.

As the storage period increases, this milky scent fades away and develops a sour or rancid odor when bacteria get into the cheese.

So if your cheese is stinking or giving an off smell, you should discard the leftovers immediately.

  • Firmness in Texture

Mozzarella cheese is quite soft in texture; thus, if it gets a lot of air exposure, then it dries out.

So one needs to secure the slice from the air, for which they can use plastic wraps.

The cheese does not get harder from inside that early; therefore, if the texture is firm, then it indicates prolonged exposure to air.

Therefore you should avoid the consumption of hard or firm cheese as it can cause severe damage.

How to Store Mozzarella Cheese?

  • Storage in Liquid

If you have ever bought cheese in an airtight container, then you know it comes with a liquid.

The liquid preserves the quality of the cheese as the liquid is whey.

This is a byproduct that produces at the time of making mozzarella cheese.

This will keep the cheese moist and preserve it from early drying.

  • Defrost Needed

Some people prefer freezing the cheese; if you are one of those, then be sure to defrost it before usage.

Using the cheese directly from the fridge can make it worse, as sudden temperature changes can cause the mozzarella cheese to go rancid.

Thus set it out for 1 hour to defrost before using or eating.

  • Use Plastic or Cheese Wrap

Cheese gets dry and develops bacteria if they get close to the outer elements.

So one needs to add a protective layer that can prevent its drying and restrict the moisture of cheese within it.

For adding coverage, you can wrap the mozzarella cheese in a wrap and extent its life.


Leftover slices might tempt you, but don’t consume them before you look for bad signs.

If anyone does not prefer storage in a container, resealing Ziploc bags is also a good option.

These bags do not let air and moisture intact with cheese but remember that the bag does not contain air.

One should squeeze all the air out before storage.

Storage at high temperatures should be avoided if you want to store the mozzarella cheese for an extended period.

Thus it would be best to keep it in a cool and dark place like a fridge or freezer.
