Does Fresh Mozzarella Go Bad?

Fresh mozzarella, a soft and creamy cheese made from cow’s or buffalo’s milk, is a favorite among cheese enthusiasts and culinary enthusiasts alike. But does fresh mozzarella go bad? The answer is yes, like any diary product, fresh mozzarella can spoil if not handled and stored correctly.

How long does Fresh Mozzarella last?

Fresh mozzarella, known for its soft and creamy texture, is a beloved cheese choice for many. But how long can you keep it before it goes bad? The shelf life of fresh mozzarella depends on various factors such as its production process, packaging, and storage conditions. Here’s a breakdown:

How long does Fresh Mozzarella last

  1. Unopened Fresh Mozzarella: When stored properly in the refrigerator at temperatures below 40°F (4°C), unopened fresh mozzarella can last up to two to three weeks from the date of purchase.
  2. Opened Fresh Mozzarella: Once you open the package, the clock starts ticking. Fresh mozzarella typically stays good for about three to five days when refrigerated in an airtight container or resealable bag.
  3. Frozen Fresh Mozzarella: If you have extra fresh mozzarella and want to extend its shelf life, you can freeze it. Properly wrapped and stored in the freezer at temperatures below 0°F (-18°C), fresh mozzarella can retain its quality for up to two to three months.

Remember, these time frames are approximate and can vary based on the cheese’s quality, freshness, and storage conditions. Always use your senses and judgment to determine if the fresh mozzarella is still safe to eat.

How to store Fresh Mozzarella?

Storing mozzarella is pretty similar to storing blue cheese. To maximize the shelf life and maintain the quality of your fresh mozzarella, follow these storage tips:

How to store Fresh Mozzarella

  1. Leave it in the Original Packaging: Fresh mozzarella is often sold in brine or whey to keep it moist and flavorful. Keep the cheese in its original packaging until you’re ready to use it.
  2. Keep it Refrigerated: Fresh mozzarella can go bad quite fast, so refrigeration is crucial. Store it in the coldest part of your refrigerator, such as the back or bottom shelf, where the temperature remains constant. Ensure the temperature is below 40°F (4°C).
  3. Protect from Air Exposure: Air exposure can lead to spoilage and affect the quality of fresh mozzarella. Once you open the package, tightly wrap the remaining cheese in plastic wrap or transfer it to an airtight container.
  4. Avoid Excessive Moisture: Excess moisture can cause the cheese to become slimy or develop mold. If necessary, pat the cheese dry with a paper towel before storing it.

How to Tell if Fresh Mozzarella has gone Bad?

When it comes to determining if your fresh mozzarella has gone bad, there are several key indicators to consider. Let’s explore them in detail:


Inspect the appearance of the mozzarella for any visible changes that may indicate spoilage:

  • Discoloration: If you notice any significant yellowing, dark spots, or patches on the surface of the cheese, it may be a sign that it has gone bad.
  • Mold: Check for the presence of mold on the mozzarella. While some molds on cheese are harmless, others can be toxic. If you see fuzzy, greenish, or black mold growth, it’s best to discard the cheese entirely.
  • Excessive Moisture: If the mozzarella appears excessively wet, with visible pools of liquid or a slimy texture, it may be an indication of spoilage. This could be due to bacterial growth or improper storage.


Give your fresh mozzarella a sniff to assess its aroma:

  • Unpleasant Odor: Fresh mozzarella should have a mild, milky scent. If you detect a strong or sour smell, it’s likely that the cheese has spoiled. A pungent or rotten odor is a clear sign to avoid consuming it.


Feel the texture of the mozzarella to check for any abnormalities:

  • Sliminess: If the cheese feels slimy or sticky to the touch, it has likely started to break down and is no longer fresh.
  • Graininess: Fresh mozzarella should have a smooth and elastic texture. If you notice a grainy or crumbly texture, it may indicate that the cheese has deteriorated and is no longer suitable for consumption.


Trust your taste buds to evaluate the flavor of the mozzarella:

  • Off-putting Taste: If your fresh mozzarella tastes sour, bitter, or has an unusual or unpleasant flavor, it’s a clear indication that it has gone bad. Consuming spoiled cheese can lead to foodborne illnesses, so it’s best to discard it.


Take a closer look at the packaging of your fresh mozzarella for any signs of spoilage:

  • Bloating or Swelling: If you notice that the packaging is bloated or swollen, it could be a result of gas production by bacteria. This indicates that the cheese has likely spoiled, and it’s safer to dispose of it.

It’s important to note that the presence of any of these signs individually or collectively suggests that the fresh mozzarella has gone bad. When in doubt, it’s better to err on the side of caution and avoid consuming potentially spoiled cheese to prevent any health risks.

How to freeze Fresh Mozzarella?

If you have excess fresh mozzarella and want to extend its shelf life, freezing is an option. Follow these steps to freeze fresh mozzarella properly:

  1. Preparation: Cut the fresh mozzarella into smaller portions or slices. This will make it easier to use later on.
  2. Wrap it Tight: Wrap each portion tightly in plastic wrap or place them in airtight freezer bags. Ensure all air is removed to prevent freezer burn.
  3. Label and Date: Don’t forget to label each package with the contents and the date of freezing. This will help you keep track of its freshness.
  4. Freeze it: Place the wrapped portions in the freezer, ideally at temperatures below 0°F (-18°C). Frozen fresh mozzarella can typically maintain its quality for up to two to three months.

It’s important to note that freezing fresh mozzarella can alter its texture slightly, making it less ideal for consumption on its own. However, it can still be used in cooked dishes like lasagna or baked pasta where texture changes are less noticeable.

When you’re ready to use the frozen fresh mozzarella, thaw it overnight in the refrigerator. It’s best to use it within a day or two after thawing for optimal taste and texture.


What happens if you eat expired mozzarella?

Consuming expired mozzarella can pose health risks. Eating spoiled or expired mozzarella may result in foodborne illnesses such as bacterial infections or food poisoning. Symptoms can include stomach cramps, nausea, vomiting, diarrhea, and in severe cases, fever or dehydration. It’s crucial to prioritize your well-being and avoid consuming expired mozzarella.

Can I freeze fresh mozzarella in its original packaging?

It’s best to transfer the fresh mozzarella to airtight containers or wrap it tightly in plastic wrap before freezing. The original packaging may not provide adequate protection against freezer burn.

Can cooking expired mozzarella kill bacteria and make it safe to eat?

Cooking expired mozzarella may kill some bacteria, but it won’t necessarily eliminate all potential health risks. Bacteria can produce toxins that are heat-stable and may still cause illness even if the cheese is cooked. It’s best to err on the side of caution and avoid using expired mozzarella in cooking.

Can I cut off the moldy part of mozzarella and still eat the rest?

It’s not recommended to consume mozzarella with visible mold, even if you cut off the affected part. Mold can penetrate deeper into the cheese than what meets the eye, and there may be invisible mold spores present. It’s best to discard the entire moldy mozzarella to prevent potential health risks.

Wrapping up

Fresh mozzarella is a delightful cheese that can elevate your culinary creations, but it does have a limited shelf life. Remember to store it properly in the refrigerator, use your senses to assess its quality, and freeze it if needed. By following these guidelines, you’ll ensure that your fresh mozzarella remains fresh, delicious, and safe to eat. So go ahead, enjoy your Caprese salads, homemade pizzas, or any other dish that calls for this creamy cheese with confidence!
