How to Tell if Mozzarella Cheese is Bad – Signs and Storage Tips

Ever found yourself in front of the fridge, staring at a block of mozzarella and wondering, "Is my mozzarella cheese expired?" You're not alone. As a cheese-lover myself, I've been there too, and the uncertainty can be frustrating. Whether you're preparing a pizza, or just snacking, no one wants to risk a spoiled cheese ruining their day. But fear not, I've gathered clear, easy-to-follow guidelines on how to tell if mozzarella cheese is bad. You'll learn about the spoilage indicators for mozzarella cheese, how to assess the freshness, and other key factors to consider. Basically, this is your ultimate guide to distinguishing good and bad mozzarella cheese.

**Key Takeaways**

1. **Understanding the Shelf Life:** Fresh mozzarella can last up to a week past the label's date and, once opened, for about 7 days. Mozzarella blocks have a longer shelf life, lasting about 3 weeks past the label's date.

2. **Identifying Spoilage Signs:** Look out for mold, discolorations, a sour smell, or taste. Also, if your cheese has dried out or hardened, it might be time to throw it out.

3. **Proper Storage Techniques:** Fresh mozzarella should be stored in the liquid that comes with it, or in water with salt if it's salted. Always keep it refrigerated to prevent spoilage.

# How to Tell If Mozzarella Cheese Is Bad

### Smell and Appearance of Bad Mozzarella

One of the easiest ways to tell if your mozzarella cheese has gone bad is by using your senses of smell and sight. Fresh mozzarella should have a mild, milky aroma.

If you take a whiff and it smells sour or unpleasant, that's a clear sign that it's gone bad. Trust your nose on this one!

Fresh mozzarella should ideally exhibit a smooth, shiny, and slightly elastic texture in terms of appearance. A dry, cracked look or uneven coloration might suggest that the cheese is spoiled.

If any visible mold is spotted on the cheese, it's an unmistakable sign to discard the mozzarella.

### Texture Changes in Spoiled Mozzarella

Now let's talk about texture. When mozzarella cheese goes bad, it can undergo some noticeable changes in texture.

Fresh mozzarella should be soft and slightly springy to the touch. If you find that the cheese has become hard, rubbery, or crumbly, it's a good indication that it's past its prime.

Another texture change to watch out for is excessive moisture or stickiness. While mozzarella cheese is known for its creamy texture, if it becomes overly wet or slimy, that's a sign that it's spoiled.

### Testing Fresh Mozzarella for Spoilage

So, you've got a fresh mozzarella cheese in your hand, but you're not sure if it's still good to eat.

No worries, I've got a simple test for you!

Take a small piece of the cheese and give it a taste. Fresh mozzarella should have a mild and slightly salty flavor.

If you detect any sour or bitter notes, it's a surefire sign that it's gone bad.

### Evaluating Shredded Mozzarella for Freshness

Shredded mozzarella cheese is a staple in many households, especially for making homemade pizzas or adding a cheesy topping to pasta dishes. But how can you tell if your shredded mozzarella is still fresh?

Well, here's a tip for you: pay attention to the packaging.

If the bag of shredded mozzarella is bloated or has visible mold, it's time to toss it out. And of course, give it a sniff.

If it smells sour or off, it's a definite sign of spoilage.

### Reading Expiry Date on Mozzarella Packages

Now, let's talk about expiry dates.

Most mozzarella packages come with an expiry date printed on them. It's important to check this date before purchasing or consuming the cheese.

However, keep in mind that the expiry date is just a guideline.

Fresh mozzarella can often last for up to a week past the date on the label if stored properly.

### How to assess the freshness of expired mozzarella?

But what if your mozzarella cheese has passed its expiry date? Does that mean it's automatically bad?

Not necessarily! While it's always best to follow the expiry date as a general rule, there are a few factors to consider.

First, check the appearance and smell of the cheese.

If it still looks and smells fresh, it's worth giving it a taste. Remember, trust your taste buds!

If it tastes off or has an unpleasant flavor, it's time to say goodbye to that mozzarella.

But if it still tastes good, you can go ahead and enjoy it.

## How to Detect Bad Mozzarella Cheese Stored in Water?

Now, let's move on to mozzarella cheese that's stored in water.

This type of mozzarella is typically packaged in liquid, either water or brine, to help maintain its freshness. But how can you tell if the mozzarella stored in water has gone bad?

Let me break it down for you.

### Signs of Contamination in Water-Stored Mozzarella

It's crucial to monitor the condition of the water in which mozzarella is stored. Should the water appear cloudy, exhibit discoloration, or emit a foul odor, these signs may suggest that the mozzarella has been contaminated.

Under such circumstances, it's advisable to err on the side of caution and dispose of the cheese.

## How to Keep Mozzarella Cheese Fresh?

Now that we've covered how to detect bad mozzarella, let's talk about how to keep it fresh for as long as possible. Here are a few tips to help you out:

### Storing Mozzarella in the Refrigerator

Storing mozzarella effectively involves using your refrigerator. It's crucial to always keep fresh mozzarella refrigerated at a temperature range of 35°F to 40°F (1.6°C to 4.4°C). This method helps to deter the growth of bacteria, allowing the cheese to stay fresh for an extended period.

To store an unopened package of mozzarella, simply keep it refrigerated until you're ready to use it. Once opened, it's important to take some additional steps to maintain its freshness.

### Preserving Fresh Mozzarella in Liquid

If you have leftover fresh mozzarella that's stored in liquid, there are a few things you can do to keep it fresh. First, strain the liquid from the cheese.

Then, wrap the cheese tightly in plastic wrap, ensuring there are no air pockets.

This helps to prevent moisture loss and maintain the cheese's creamy texture.

Alternatively, you can store the mozzarella in the same liquid it came in.

Make sure the cheese is fully submerged in the liquid, seal the container, and refrigerate it. It's important to note that if you choose this method, you should replace the liquid every other day to keep the mozzarella fresh.

## Does Mozzarella Cheese Get Spoiled if Not Refrigerated?

Now, you might be wondering if mozzarella cheese can get spoiled if it's not refrigerated.

The short answer is yes. Mozzarella is a perishable dairy product, and leaving it at room temperature for an extended period can lead to spoilage.

### Effects of Not Refrigerating Mozzarella

When mozzarella cheese is not refrigerated, it becomes more susceptible to bacterial growth. This can result in the cheese developing an off smell, taste, or even visible mold.

### Shelf-Life of Unrefrigerated Mozzarella

If you accidentally leave your mozzarella cheese out of the refrigerator for a short period, it's not automatically spoiled. However, it's important to use your senses to assess its freshness.

Check for any changes in appearance, smell, or taste.

If everything seems normal, you can go ahead and enjoy it.

But if you notice any signs of spoilage, it's best to discard the cheese to avoid any potential foodborne illnesses.
