Can You Eat Cheese Past the Expiration Date?

Can You Eat Cheese Past the Expiration Date? A Deep Dive into Dairy Dating

Whether you can eat cheese past its expiration date depends heavily on the type of cheese and how it’s been stored, but the short answer is: often, yes, you can, as expiration dates are often best-by dates rather than safety deadlines. However, proceed with extreme caution and use your senses to evaluate the cheese’s quality before consuming it.

Understanding Cheese Dates: Best By vs. Use By

Decoding the language on cheese packaging is the first step in making an informed decision about its edibility after the printed date. Two main types of dates are commonly used: “best by” and “use by.” These aren’t interchangeable, and understanding the difference is crucial.

• “Best by” dates: These dates indicate the manufacturer’s estimate of when the cheese will be at its peak flavor and texture. After this date, the quality may diminish, but the cheese might still be safe to eat if stored properly. Think of it as a suggestion, not a strict command.

• “Use by” dates: These dates are more about safety and suggest that the cheese may not be safe to consume after this date, particularly if it hasn’t been stored correctly. These dates are typically found on perishable items that are more likely to harbor harmful bacteria.

Cheese Types and Their Longevity

The type of cheese significantly impacts its shelf life and its edibility beyond the expiration date. Hard cheeses, due to their lower moisture content, generally last longer than soft cheeses.

Proper Cheese Storage: The Key to Longevity

Regardless of the type, proper storage is paramount to extending the life of cheese and minimizing the risk of spoilage.

• Refrigeration: Store cheese in the refrigerator, ideally between 35°F and 45°F (2°C and 7°C).
• Wrapping: Wrap cheese tightly in wax paper, parchment paper, or cheese paper. Plastic wrap can trap moisture and promote mold growth.
• Airtight Containers: For softer cheeses, consider storing them in airtight containers to prevent them from drying out or absorbing odors from other foods.
• Separate Storage: Keep different types of cheese separate to prevent cross-contamination of flavors and mold.
• Avoid Freezing: While some cheeses can be frozen, the texture and flavor often suffer significantly. Only freeze hard cheeses if absolutely necessary, and be prepared for a change in quality.

Recognizing Signs of Spoilage

Even with proper storage, cheese can eventually spoil. Knowing what to look for is essential for determining whether it’s safe to eat.

• Mold: While some cheeses, like blue cheese, naturally contain mold, the appearance of mold on other types of cheese is a warning sign. For hard cheeses, you can often cut away the moldy area (at least an inch around it), but discard soft cheeses entirely if mold is present.
• Off Odors: A sour, ammonia-like, or otherwise unpleasant odor is a clear indication that the cheese has gone bad.
• Discoloration: Unusual discoloration, such as a slimy or excessively yellow surface, can indicate spoilage.
• Texture Changes: A dry, cracked, or slimy texture can also be a sign that the cheese is no longer safe to eat.
• Taste Test (Proceed with Caution): If the cheese looks and smells okay, you can try a tiny piece. If it tastes sour, bitter, or otherwise off, discard it. Do not swallow a potentially spoiled cheese.

The Role of Salt and Acidity in Preservation

Salt and acidity play vital roles in preserving cheese and inhibiting the growth of harmful bacteria. Hard cheeses, which are often salted heavily, tend to last longer than fresh cheeses, which have higher moisture content and lower acidity. The acidity of some cheeses also naturally inhibits bacterial growth.

Common Mistakes in Cheese Storage and Consumption

Avoiding common mistakes in cheese storage and consumption is critical for ensuring its safety and quality.

• Storing Cheese at Room Temperature: Cheese should always be refrigerated to prevent bacterial growth.
• Using Contaminated Utensils: Always use clean knives or utensils when cutting cheese to avoid introducing bacteria.
• Leaving Cheese Unwrapped: Exposure to air can cause cheese to dry out and become susceptible to spoilage.
• Ignoring Expiration Dates Completely: While expiration dates are not always strict deadlines, they should be considered as a guideline.

Frequently Asked Questions (FAQs)

How long can hard cheese like cheddar last past its expiration date?

Hard cheeses like cheddar can often last for several weeks or even months past their expiration date if stored properly in the refrigerator. The low moisture content and high salt content make them less susceptible to spoilage. Be sure to inspect it for mold and off-odors before consuming.

Is it safe to eat cheese with mold on it?

It depends on the type of cheese. For hard cheeses, you can typically cut away the mold (at least one inch around the moldy area) and still consume the rest of the cheese. However, for soft cheeses, you should discard the entire piece if any mold is present, as the mold’s spores can easily spread throughout the cheese.

What does “use by” date mean on cheese packaging?

A “use by” date indicates the manufacturer’s recommendation for when the cheese should be consumed for optimal quality and safety. After this date, there is an increased risk of spoilage and potential foodborne illness, especially if the cheese has not been stored properly.

How can I tell if my soft cheese (like brie or camembert) has gone bad?

Signs that soft cheese has gone bad include: an ammonia-like smell, excessive sliminess, a sour taste, or the presence of mold. If you notice any of these signs, it is best to discard the cheese.

Can I freeze cheese to extend its shelf life?

While you can freeze some cheeses, the texture and flavor will likely be affected. Hard cheeses freeze better than soft cheeses. When thawed, the cheese may become crumbly and lose some of its flavor.

What’s the best way to store cheese in the refrigerator?

The best way to store cheese in the refrigerator is to wrap it tightly in wax paper, parchment paper, or cheese paper and store it in the crisper drawer or another cold area. Avoid using plastic wrap, as it can trap moisture and promote mold growth.

Does vacuum-sealing cheese extend its shelf life?

Yes, vacuum-sealing cheese can significantly extend its shelf life by preventing exposure to air, which can cause the cheese to dry out and spoil. However, even vacuum-sealed cheese should be stored properly in the refrigerator.

What should I do if my cheese has a slightly sour smell?

A slightly sour smell can indicate that the cheese is starting to spoil. It’s best to err on the side of caution and discard the cheese, especially if it is a soft cheese.

Is processed cheese safer to eat past its expiration date than natural cheese?

Processed cheese, such as American cheese slices, often contains preservatives and has a higher salt content, which can help extend its shelf life. However, it’s still important to inspect the cheese for any signs of spoilage before consuming it.

How does the fat content of cheese affect its shelf life?

Higher fat content generally doesn’t directly correlate with a longer or shorter shelf life. The moisture content, salt content, and acidity are more significant factors determining how long cheese will last.

If I cut off the mold on hard cheese, is the rest of the cheese safe to eat?

Generally, yes, cutting away the mold (at least one inch around the moldy area) on hard cheese makes the rest of the cheese safe to eat. However, be sure to use a clean knife and avoid touching the mold with the knife or the rest of the cheese.

Can eating spoiled cheese make you sick?

Yes, eating spoiled cheese can cause foodborne illness, with symptoms such as nausea, vomiting, diarrhea, and stomach cramps. If you suspect that you have eaten spoiled cheese, seek medical attention if your symptoms are severe or prolonged.
