Blue cheese, with its distinctive veiny appearance and pungent aroma, is a favorite among cheese enthusiasts. However, like all dairy products, blue cheese has a limited shelf life. If you’ve found a block of blue cheese in your fridge that’s past its expiration date, you might be wondering: can you eat blue cheese out of date? In this article, we’ll delve into the world of blue cheese, exploring its unique characteristics, the risks associated with consuming expired blue cheese, and provide guidance on how to determine whether your blue cheese is still safe to eat.
Understanding Blue Cheese
Before we dive into the topic of expired blue cheese, it’s essential to understand what makes blue cheese unique. Blue cheese is a type of cheese that’s been infused with a type of mold, typically Penicillium roqueforti. This mold gives blue cheese its distinctive veiny appearance and pungent aroma. The mold also contributes to the cheese’s strong, tangy flavor.
Blue cheese is typically made from cow’s milk, although some varieties are made from sheep’s or goat’s milk. The cheese is aged for several months, during which time the mold grows and develops its characteristic flavor and texture.
The Aging Process
The aging process is crucial in determining the quality and safety of blue cheese. During the aging process, the cheese is regularly turned and monitored to ensure that the mold grows evenly and doesn’t become too aggressive. The aging process can last anywhere from a few months to several years, depending on the type of blue cheese.
Types of Blue Cheese
There are several types of blue cheese, each with its unique characteristics and aging process. Some popular types of blue cheese include:
- Roquefort: A French blue cheese made from sheep’s milk, aged for at least five months.
- Gorgonzola: An Italian blue cheese made from cow’s milk, aged for at least three months.
- Stilton: An English blue cheese made from cow’s milk, aged for at least nine months.
The Risks of Consuming Expired Blue Cheese
While blue cheese is generally safe to eat, consuming expired blue cheese can pose some risks. Here are some potential risks to consider:
- Food Poisoning: Expired blue cheese can harbor bacteria like Listeria, E. coli, and Salmonella, which can cause food poisoning. Symptoms of food poisoning include nausea, vomiting, diarrhea, and stomach cramps.
- Mold Overgrowth: If the mold in the blue cheese becomes too aggressive, it can produce toxins that can cause allergic reactions or respiratory problems.
- Off-Flavors and Textures: Expired blue cheese can develop off-flavors and textures, which can be unpleasant to eat.
How to Determine if Blue Cheese is Still Safe to Eat
So, how can you determine if your blue cheese is still safe to eat? Here are some tips:
- Check the Expiration Date: Check the expiration date on the packaging to ensure that the blue cheese is still within its recommended shelf life.
- Look for Visible Signs of Spoilage: Check the blue cheese for visible signs of spoilage, such as mold, slime, or an off smell.
- Check the Texture: Blue cheese should have a crumbly, creamy texture. If the texture is slimy or soft, it may be a sign that the cheese has gone bad.
- Smell the Cheese: Blue cheese should have a pungent, tangy aroma. If the cheese smells sour or unpleasantly strong, it may be a sign that it’s gone bad.
What to Do with Expired Blue Cheese
If you’ve determined that your blue cheese is expired, it’s best to err on the side of caution and discard it. However, if you’re unsure whether the cheese is still safe to eat, you can try the following:
- Cut Off the Moldy Parts: If the mold is only visible on the surface of the cheese, you can try cutting off the moldy parts and using the rest of the cheese.
- Cook the Cheese: Cooking the cheese can kill off any bacteria or mold that may be present. However, this method is not foolproof, and it’s still possible to get food poisoning from cooked expired blue cheese.

What happens if I eat blue cheese past its expiration date?
Eating blue cheese past its expiration date can pose some risks to your health. Blue cheese is a type of soft cheese that contains mold, which can continue to grow even after the expiration date. If the cheese is not stored properly, the mold can produce toxins that can cause food poisoning. However, the severity of the risks depends on various factors, such as the type of blue cheese, how it is stored, and the individual’s immune system.
If you eat blue cheese past its expiration date and it has been stored properly in the refrigerator at a temperature below 40°F (4°C), the risks are relatively low. You may experience some gastrointestinal symptoms, such as bloating, gas, or diarrhea, but these symptoms are usually mild and temporary. However, if the cheese has been contaminated with harmful bacteria or mold, you may experience more severe symptoms, such as vomiting, fever, or abdominal pain. In such cases, it is essential to seek medical attention immediately.
How can I tell if blue cheese has gone bad?
To determine if blue cheese has gone bad, you need to check its appearance, smell, and texture. Fresh blue cheese typically has a strong, pungent aroma and a creamy, crumbly texture. If the cheese has an off smell, slimy texture, or visible signs of mold, it is likely to have gone bad. You should also check the expiration date on the packaging and look for any signs of tampering or damage.
If you are still unsure whether the blue cheese has gone bad, it is better to err on the side of caution and discard it. Blue cheese can be a breeding ground for bacteria and mold, and consuming spoiled cheese can lead to food poisoning. If you notice any unusual changes in the cheese’s appearance, smell, or texture, it is best to discard it and purchase a fresh batch.
Can I still use blue cheese if it’s past its expiration date for cooking?
If blue cheese is past its expiration date, it is generally not recommended to use it for cooking, especially if you are planning to serve the dish to vulnerable individuals, such as the elderly, pregnant women, or people with weakened immune systems.
