Can You Eat Out of Date Mozzarella?

Mozzarella cheese, with its mild and creamy flavor, is a versatile ingredient that finds its way into countless dishes, from pizzas and lasagnas to salads and sandwiches.

But what happens when that tub of mozzarella lurking in the back of your fridge has passed its expiration date? Can you still consume it without risking your health?

In this article, we’ll explore the world of out-of-date mozzarella cheese and answer common questions like, “Can you eat expired mozzarella cheese?” and “Can out-of-date mozzarella make you sick?”

Can You Eat Expired Mozzarella Cheese?

The short answer is, yes, you can eat expired mozzarella cheese in many cases. The “expiration date” or “best before” date on food products is not a strict indicator of spoilage but rather a suggestion of when the product is at its peak quality.

Cheese, including mozzarella, can often be consumed safely even after this date has passed. However, it’s essential to understand the distinction between “expiration date” and “sell-by date” or “use-by date.”

Expiration Date

This date is typically found on perishable goods like dairy products, but it does not necessarily mean that the product is unsafe to consume after that date.

It usually indicates the manufacturer’s estimate of when the product will be at its best quality.

Sell-By Date/Use-By Date

These dates are more about the product’s freshness and are meant for retailers and consumers to know when the product is at its peak quality.

It doesn’t necessarily mean that the product is unsafe to eat afterward, especially if it has been stored properly.

When it comes to mozzarella cheese, it tends to be a resilient dairy product that can withstand a bit of aging without posing a significant risk to your health. However, several factors need to be considered.

Can Out-of-Date Mozzarella Make You Sick?

While eating mozzarella cheese past its expiration date is generally safe, there are some caveats to keep in mind:

1. Storage Conditions

How the mozzarella has been stored plays a crucial role in its safety. If the cheese has been kept in optimal conditions, such as in the refrigerator at the right temperature (around 35-40°F or 1-4°C), it is more likely to remain safe for consumption even after the expiration date.

On the other hand, if it has been left out at room temperature for extended periods or exposed to temperature fluctuations, it becomes more susceptible to bacterial growth and spoilage.

2. Appearance and Smell

Before consuming mozzarella cheese that has passed its expiration date, it’s essential to examine it closely.

If the cheese exhibits any signs of spoilage, such as mold, an off-putting odor, or an unusual texture (like being slimy or excessively dry), it’s best to discard it. If it looks and smells fine, it’s likely still safe to eat.

3. Personal Sensitivity

Some individuals may have a heightened sensitivity to foodborne illnesses and may choose to be more cautious when it comes to eating foods past their expiration date.

If you have a compromised immune system or are particularly susceptible to foodborne illnesses, it’s advisable to err on the side of caution and avoid consuming expired mozzarella cheese.

4. Taste Test

If you’re unsure about the safety of your mozzarella, you can perform a small taste test. Take a small, cautious bite to check for any unusual or unpleasant flavors. If it tastes fine, it’s probably safe to eat.

How Long Does Mozzarella Last After the Expiration Date?

The shelf life of mozzarella cheese can vary depending on several factors, including its moisture content, storage conditions, and packaging.

Here are some general guidelines:

High-Moisture Mozzarella (Fresh Mozzarella): Fresh mozzarella, the kind you find in the deli section, typically has a shorter shelf life. It’s best consumed within one to two weeks after the “sell-by” or “use-by” date if stored properly in the refrigerator. If the cheese develops mold or an off-putting smell, discard it.
Low-Moisture Mozzarella: Low-moisture mozzarella, such as the shredded or block mozzarella you might use for pizzas, has a longer shelf life. If stored correctly in an airtight container or vacuum-sealed package in the refrigerator, it can last beyond its expiration date, often by several weeks or even months. Again, perform the visual and smell tests to ensure it’s still safe to eat.

If you’re concerned about not using your mozzarella cheese before it reaches its expiration date, you can freeze it. Freezing can extend the shelf life considerably.

Simply wrap the cheese tightly in plastic wrap or aluminum foil and place it in an airtight container or freezer bag. Frozen mozzarella can last up to six months or more.

How Long Does Raw Mozzarella Last in the Fridge?

If you have raw mozzarella, also known as fresh mozzarella, you should be mindful of its relatively short shelf life. When stored correctly in the refrigerator, it typically lasts for about one to two weeks, possibly a bit longer if it was very fresh at the time of purchase.

Here are some tips to extend the shelf life of raw mozzarella:

Keep it in its original packaging or an airtight container.
Store it in the refrigerator’s coldest section, usually near the back.
Avoid exposing it to temperature fluctuations by opening the container only when needed.
Again, perform regular visual and smell checks to ensure it hasn’t spoiled.

How to Tell if Mozzarella Has Gone Bad

Knowing when mozzarella cheese has gone bad is essential for your safety and enjoyment of your dishes. Here are some signs that indicate mozzarella cheese may have spoiled:

Mold: Visible mold growth on the cheese is a clear indicator that it’s no longer safe to eat. Mold can produce mycotoxins that can be harmful if ingested.
Off-Putting Odor: A strong, unpleasant, or sour smell coming from the mozzarella is a sign of spoilage. Fresh mozzarella should have a clean, milky scent.
Texture Changes: If the mozzarella cheese has become slimy, excessively dry, or crumbly, it has likely deteriorated and should be discarded.
Unusual Taste: If the cheese has developed an off or rancid flavor, it’s best not to consume it.

Conclusion

In conclusion, eating mozzarella cheese past its expiration date is generally safe as long as the cheese has been stored properly and shows no signs of spoilage.

Keep in mind that mozzarella with higher moisture content has a shorter shelf life than low-moisture varieties. When in doubt, perform a visual and smell check, and if the cheese appears or smells off, it’s better to play it safe and discard it.

Freezing can also be an effective way to extend the shelf life of mozzarella cheese. Enjoy your mozzarella responsibly and savor its deliciousness without unnecessary worry.
