Mozzarella is a popular cheese used in a variety of dishes, from pizza to Caprese salad. It is a healthy option among dairy products due to its low-fat content and high protein. However, its high moisture content and absence of preservatives make it more susceptible to spoilage and mould growth. Proper storage is crucial to maintaining mozzarella's quality and extending its shelf life, which is typically shorter than that of harder cheeses. In this article, we will explore how fast mozzarella cheese goes bad, the signs of spoilage, and best practices for storage to ensure you can enjoy your mozzarella to the fullest.

Proper storage is key to preventing mozzarella from going bad
To maintain the quality and extend the shelf life of mozzarella, it is crucial to follow proper storage practices. If you have bought unopened mozzarella in its vacuum-sealed package, keep it in the refrigerator until you are ready to use it. It is important to never leave mozzarella at room temperature for more than two hours.
Once the package is opened, mozzarella should be stored in an airtight container in the refrigerator. This will help maintain a consistent temperature and humidity level, slowing down the growth of bacteria and mould. It is also recommended to use a designated pair of tongs or spoons to handle the cheese, as touching it with bare hands can introduce cross-contamination.
Additionally, it is important to regularly check the texture, smell, and colour of the mozzarella to assess its freshness and safety. Fresh mozzarella that has gone bad may exhibit a slimy or sticky texture. Any visible mould, such as black mould or blue spots on white mozzarella, indicates that the cheese should be discarded.
By following these proper storage practices and regularly checking for signs of spoilage, you can prevent mozzarella from going bad and enjoy its delicious flavour and texture for longer.

High moisture content and lack of preservatives cause faster moulding
Mozzarella is a soft cheese with a high moisture content. This means that it is prone to spoilage faster than other cheeses, especially those that are harder and have lower moisture content, such as cheddar or Parmigiano Reggiano. The high moisture content in mozzarella creates an environment that is conducive to mould growth, especially when the cheese is shredded or exposed to air, leading to a shorter shelf life.
Additionally, mozzarella typically contains little to no preservatives, which further contributes to its faster spoilage. Preservatives are commonly used in food products to inhibit the growth of microorganisms, such as mould, and to extend the product's shelf life. However, in the case of mozzarella, the absence of preservatives allows mould to grow more rapidly.
The storage conditions and handling practices also play a crucial role in the moulding process. For instance, if mozzarella is left at room temperature for an extended period, it can accelerate mould growth. Proper storage practices, such as keeping mozzarella in its original vacuum-sealed packaging and maintaining a consistent temperature in the refrigerator, can help extend its shelf life and inhibit mould growth.
To determine if mozzarella has gone bad, it is important to examine its texture, smell, and colour. Fresh mozzarella that has spoiled may exhibit a slimy or sticky texture. Visible mould growth, particularly in the form of black mould or blue spots, indicates that the cheese should be discarded. Discolouration, such as an orange hue, can also be a sign of spoilage, although this may sometimes be due to harmless bacteria rather than mould.
In summary, the high moisture content and lack of preservatives in mozzarella create an environment that promotes mould growth, resulting in a shorter shelf life compared to other cheeses. Proper storage practices and regular inspection of the cheese's texture, smell, and colour can help extend its freshness and ensure it is safe to consume.

It's safe to eat if it smells and tastes fine, with no mould
Mozzarella is a soft cheese with a high moisture content and no preservatives, which means it can spoil faster than other cheeses if not stored properly. It is considered a healthy option among dairy products due to its low fat and high protein content. However, its high moisture content means it is more susceptible to mould growth. Even when stored unopened in its original packaging, mozzarella can develop an orange hue, which is often due to harmless bacteria rather than mould.
When assessing whether it is safe to eat mozzarella, it is important to examine its texture, smell, and colour. Fresh mozzarella that has gone bad may exhibit a slimy or sticky texture. Any visible mould on fresh mozzarella indicates that it should be discarded, and discoloration such as white mozzarella developing black mould or blue spots renders it unsafe for consumption.
However, if the mozzarella smells and tastes fine, with no mould, it is generally safe to consume. This is because the "best before" dates on cheese are not actual expiration dates. Even vacuum-sealed mozzarella can remain edible for several months past the printed date, though it may develop a stronger flavour.
To extend the shelf life of mozzarella, proper storage is crucial. It should always be kept in its original vacuum-sealed packaging and refrigerated, never left out at room temperature for more than two hours. By following these practices and regularly checking for any signs of spoilage, you can safely enjoy mozzarella in a variety of dishes, from Caprese salads to pizzas and pasta dishes.

Unopened mozzarella can last months after the expiration date
Mozzarella is a soft cheese with a high moisture content. This means that it has a shorter shelf life than harder cheeses such as cheddar or Parmigiano Reggiano. Proper storage is crucial to maintaining mozzarella's quality and extending its shelf life. If stored properly, unopened mozzarella can last for months after its expiration date.
The best way to store unopened mozzarella is in its original vacuum-sealed packaging in the fridge. This will help to maintain its freshness and keep it from spoiling. Even when stored unopened, mozzarella can develop an orange hue due to bacteria, but this is usually harmless. However, if the cheese becomes slimy or sticky, or if there is any visible mould, it should be discarded.
The high moisture content of mozzarella creates an environment conducive to mould growth, which is why it spoils faster than other cheeses. To minimize the risk of bacterial growth and foodborne illnesses, it is important to follow general guidelines for proper storage. This includes keeping the cheese refrigerated and never leaving it out at room temperature for more than two hours.
Some people choose to freeze their unopened mozzarella to extend its shelf life even further. While this may affect the texture and taste of the cheese, it can be a good option for those who don't plan on using it right away. Ultimately, as long as the cheese looks, smells, and tastes fine, it is generally safe to consume, even if it is past its expiration date.
While unopened mozzarella can last for months past its expiration date, once it is opened, it should be consumed within a few days to a week to ensure freshness and prevent mould growth. Proper storage, such as keeping it in an airtight container in the fridge, can help extend its shelf life slightly, but opened mozzarella will not last as long as unopened cheese.

Spoilage signs: slimy texture, mould, or discoloration
Fresh mozzarella is a soft cheese with a high moisture content, which means it can spoil faster than harder cheeses like cheddar or Parmigiano Reggiano if not stored properly. When checking if your mozzarella has gone bad, look for the following signs:
Slimy texture
If your mozzarella has a slimy or sticky texture, it has likely gone bad. This is a common sign of spoilage in fresh mozzarella due to its high moisture content.
Mould growth
Any visible mould on fresh mozzarella indicates that it should be discarded. Mozzarella can develop mould even when left unopened, and it tends to mould faster than other cheeses due to its high moisture content and absence of preservatives. This mould can appear as black or blue spots on white mozzarella, or as an orange hue on the cheese, which is caused by bacteria.
Discolouration
In addition to mould, discolouration can also be a sign of spoilage. If your mozzarella has developed black or blue spots, it is no longer safe to eat.
It is important to note that mozzarella should always be stored in the fridge and never left out at room temperature for more than two hours to minimise the risk of spoilage and foodborne illnesses. Proper storage can help extend the shelf life of mozzarella and maintain its freshness.
