Cheese is one of the most beloved foods in the world, with a rich history and diverse range of flavors and textures. From tangy feta to creamy brie, there’s a type of cheese out there to suit every taste. But what happens when cheese goes bad? Can you still eat it, or will it make you sick? In this article, we’ll delve into the world of expired cheese and explore the risks and consequences of consuming it.
The Shelf Life of Cheese: What You Need to Know
Before we dive into the risks of eating expired cheese, it’s essential to understand the concept of shelf life and how it applies to dairy products. The shelf life of cheese refers to the length of time it remains safe to eat and retain its quality. This period varies depending on factors such as the type of cheese, storage conditions, and handling practices.
In general, cheese can be broadly classified into two categories: soft and hard. Soft cheeses, like brie and feta, have a higher moisture content and are more prone to spoilage. They typically have a shorter shelf life, ranging from a few weeks to a few months. Hard cheeses, like cheddar and parmesan, have a lower moisture content and are more durable. They can last for several months to a year or more when stored properly.
Factors Affecting Cheese Shelf Life
Several factors can impact the shelf life of cheese, including:
- Storage temperature: Cheese should be stored in the refrigerator at a consistent temperature below 40°F (4°C). Higher temperatures can cause cheese to spoil faster.
- Humidity: Cheese should be stored in a controlled humidity environment to prevent moisture from accumulating and promoting bacterial growth.
- Handling: Cheese should be handled gently to prevent damage and contamination. Cutting, wrapping, and storing cheese properly can help extend its shelf life.
- Type of cheese: As mentioned earlier, soft cheeses are more prone to spoilage than hard cheeses.
- Packaging: Cheese packaged in vacuum-sealed bags or airtight containers can last longer than those wrapped in paper or plastic wrap.
The Risks of Eating Expired Cheese: What Can Happen?
Now that we’ve established the importance of shelf life, let’s explore the risks associated with eating expired cheese.
Foodborne Illnesses
The most significant risk of eating expired cheese is foodborne illness. When cheese spoils, it can become a breeding ground for harmful bacteria like L. monocytogenes, E. coli, and Salmonella. These bacteria can cause a range of illnesses, from mild symptoms like nausea and diarrhea to life-threatening conditions like listeriosis and sepsis.
At-Risk Groups

Conclusion: The Verdict on Expired Cheese
In conclusion, while expired cheese may not always be a safety risk, it’s essential to exercise caution when consuming dairy products past their expiration date. The risks of foodborne illness and unpleasant flavors, textures, and aesthetics make it better to err on the side of caution.
To enjoy your cheese safely, remember to:
- Store cheese properly: Keep cheese in the refrigerator at a consistent temperature below 40°F (4°C) and maintain a controlled humidity level.
- Check expiration dates: Regularly inspect your cheese for signs of spoilage and discard any expired or spoiled products.
- Handle cheese gently: Avoid damaging or contaminating cheese during handling and storage.
By following these guidelines, you can enjoy a wide range of delicious cheeses while minimizing the risks associated with expired cheese.
What happens if I eat expired cheese?
Eating expired cheese can cause a range of symptoms, from mild discomfort to serious illness. The severity of the reaction depends on the type of cheese, its storage conditions, and individual tolerance. In general, expired cheese can lead to stomach cramps, diarrhea, and vomiting due to the growth of harmful bacteria like E. coli, Listeria, and Salmonella.
If you’re unlucky, consuming spoiled cheese can lead to more severe health issues, such as food poisoning. This can result in dehydration, electrolyte imbalance, and even hospitalization in extreme cases. In rare instances, expired cheese can also cause allergic reactions or intolerances, especially if you have a weakened immune system or pre-existing condition.
How can I tell if cheese has gone bad?
There are several telltale signs that indicate cheese has gone bad. First, check the expiration date or “best by” date on the packaging. While this doesn’t necessarily mean the cheese is spoiled, it’s a good starting point. Next, inspect the cheese for any visible mold, sliminess, or an off smell. If you notice any of these signs, it’s best to err on the side of caution and discard the cheese.
Another sign of spoiled cheese is a change in texture or color. Fresh cheese typically has a smooth, even surface, but spoiled cheese may develop cracks, crumbles, or an unusual sheen. Some cheeses, like brie or feta, naturally have a strong aroma, but if the smell is overwhelming or unpleasantly pungent, it may be a sign of spoilage.
Can I still eat cheese past its expiration date?
In general, it’s not recommended to eat cheese past its expiration date, especially soft cheeses like brie, feta, or goat cheese. These types of cheese are more prone to spoilage and can harbor harmful bacteria. Hard cheeses like cheddar, parmesan, or gouda, on the other hand, may still be safe to consume if stored properly and show no visible signs of spoilage.
That being said, if you’re unsure whether the cheese is still good, it’s always better to err on the side of caution. Even if the cheese looks and smells fine, it’s possible that harmful bacteria are lurking beneath the surface. If you’re unsure, it’s best to discard the cheese to avoid any potential health risks.
How should I store cheese to extend its shelf life?
Proper storage is crucial to extending the shelf life of cheese. The key is to keep the cheese away from heat, light, and moisture. Ideally, store cheese in a refrigerator at a consistent temperature below 40°F (4°C). Hard cheeses can be wrapped tightly in plastic wrap or aluminum foil and stored in an airtight container. Soft cheeses, on the other hand, require special care and should be wrapped in breathable materials like wax paper or parchment paper.
It’s also essential to keep cheese away from strong-smelling foods, as it can easily absorb odors. Avoid storing cheese near heat sources like ovens or dishwashers, and never leave it at room temperature for extended periods. By following these storage tips, you can help prolong the shelf life of your cheese and reduce the risk of spoilage.
Can I freeze cheese to extend its shelf life?
Yes, freezing cheese can be an effective way to extend its shelf life, especially for hard cheeses like cheddar, parmesan, or gouda. Freezing cheese will not affect its nutritional value or flavor, and it can be stored for up to 6-12 months. However, it’s essential to wrap the cheese tightly in plastic wrap or aluminum foil to prevent freezer burn and other flavors from transferring.
When you’re ready to use the frozen cheese, simply thaw it in the refrigerator or at room temperature. Keep in mind that freezing may affect the texture of soft cheeses like brie or feta, making them more prone to crumbling or breaking. If you’re unsure about freezing a particular type of cheese, it’s always best to check with the manufacturer or a cheesemonger for advice.
Are some cheeses more prone to spoilage than others?
Yes, some cheeses are more prone to spoilage than others due to their high moisture content, acidity levels, and production methods. Soft cheeses like brie, feta, and goat cheese are more susceptible to spoilage because they have a higher moisture content, making them an ideal breeding ground for bacteria and mold.
Hard cheeses like cheddar, parmesan, and gouda, on the other hand, are generally more durable and less prone to spoilage due to their lower moisture content. However, even hard cheeses can spoil if not stored properly or if they’re contaminated during production. Blue cheeses like gorgonzola or stilton are also more prone to spoilage due to their high moisture content and strong veining, which can create an ideal environment for mold growth.
Can I get food poisoning from cheese?
Yes, it is possible to get food poisoning from cheese, especially if it’s contaminated with harmful bacteria like E. coli, Listeria, or Salmonella. Soft cheeses, in particular, are more susceptible to contamination due to their high moisture content and the potential for bacteria to multiply rapidly.
Food poisoning from cheese can cause a range of symptoms, from mild discomfort to severe illness. If you experience symptoms like vomiting, diarrhea, stomach cramps, or fever within a few hours of consuming cheese, seek medical attention immediately. In severe cases, food poisoning can lead to hospitalization, dehydration, and even death, especially in vulnerable populations like the elderly, young children, or those with weakened immune systems.
