Can mozzarella cheese go bad?

In this short article, we will provide an answer to the question “can mozzarella cheese go bad?” and the ways to tell if it is bad or fresh with some tips and warnings.

Can mozzarella cheese go bad?

Yes, the quality of mozzarella deteriorates with time, much like other meals and dairy products.

Because mozzarella is such a delicate cheese, it does not last as long as other hard cheeses.

However, the shelf life of mozzarella cheese is based on several different factors, including the kind of cheese used.

The shelf life of fresh mozzarella cheese is usually four to six weeks if it has not been opened and is stored in the refrigerator.

After it has been opened, keep mozzarella cheese refrigerated for up to a week to prolong its shelf life.

It may not deteriorate quickly, but it will certainly lack the same flavor as it had before. Maintaining adequate refrigeration allows you to eat it for about a month at a time.

Learn how to tell whether your mozzarella is bad by looking at it.

When it comes to mozzarella cheese going bad, mold is the most obvious symptom. However, there are additional signs that the cheese has grown unsuitable for eating. When in doubt, toss the cheese out of the window. In healthy people, foodborne illness may be limited to the presence of unpleasant gastrointestinal symptoms. Some germs, on the other hand, maybe hazardous, especially to pregnant women, infants, the elderly, and individuals who have weaker immune systems, among other groups. Mozzarella cheese can last up to six months when properly packed and refrigerated; however, once opened the shelf life is only approximately one month.

Check the package’s expiry date to be sure it’s still valid. The use-by date does not necessarily imply safety, and properly stored mozzarella may last for many months after it has passed its expiry date. It does, however, indicate how long the cheese’s peak flavor and freshness are expected to last.

Take a whiff of the mozzarella to determine if it has an unpleasant scent and discard it. When compared to other cheeses, mozzarella has a delicate fragrance that does not overwhelm the palate. Generally speaking, if the aroma of mozzarella is off or the cheese has a sour smell, the cheese has gone bad.

If the cheese has a disagreeable flavor, it should be avoided. However unpleasant it may be to taste a little amount of aged mozzarella, it will not make you sick. Generally speaking, if the mozzarella cheese has a nice flavor, it is okay to eat it.


Wrap the mozzarella cheese tightly in plastic wrap and place it in the refrigerator to prevent it from absorbing the flavors and odors of other dishes. Keep cheese and meat apart to prevent illness.

The freshness of mozzarella cheese is maintained for a longer time as compared to small pieces or slices, which often lose their freshness within a month or less.


You should not attempt to remove the mold from the mozzarella cheese. Mold may be safely removed from hard, low-moisture cheeses such as cheddar, Parmesan, and Swiss without causing damage to the cheese. Although food safety specialists at Clemson University Extension warn that bacteria may infect the surface of mozzarella and other semi-soft, higher-moisture cheeses, they do not believe this is the case. Avert your nose from the stench of rotting cheese. It is possible to inhale spores.

How Long Does Fresh Mozzarella Keep in the Refrigerator?

Mozzarella is served with a date on the side. When compared to parmesan or other hard cheeses, its shelf life is much shorter. Considering that mozzarella has a shelf life of between two and three weeks, stocking up on it during a sale or buying it in advance is not a good idea.

If the cheese is not opened before the expiry date, it should maintain its freshness for many days (perhaps even a week) beyond that date.

The remainder of the mozzarella should be used (or frozen) within three to seven days after opening the package.

Additionally, as previously mentioned, how the cheese is kept affects the final product’s flavor.

If you wrap the cheese in plastic wrap (or place it in a bag), it will only survive a couple of days at most. Take the extra step of keeping it submerged for a few days, and you may be able to prolong its lifespan by several days.
