It’s a common question in many kitchens: how long can cheese sit out unopened? The answer, unfortunately, is not as cut and dry as we would like it to be. While there are no definitive guidelines, there are some general tips you can follow to ensure your cheese stays fresh for as long as possible.
First and foremost, avoid leaving cheese out at room temperature for extended periods of time. Cheese is best stored in the refrigerator where it will stay fresh for several weeks (unopened) or up to two months (opened). If you do need to leave your cheese out for a short period of time, be sure to wrap it tightly in wax paper or foil so that it doesn’t dry out.
If you’re like most people, you probably have a few unopened packages of cheese in your fridge. But how long can they sit there before they go bad?
The answer may surprise you.
According to the U.S. Department of Agriculture, unopened hard and semisoft cheeses can be stored at room temperature for two to four weeks! That’s right – those little blocks of cheddar or mozzarella in your fridge are good for up to a month, as long as they remain unopened.
So why is this?
It turns out that cheese is actually a pretty durable food. The high fat content prevents bacteria from growing, and the salt acts as a preservative. As long as the package is intact, the cheese inside should be just fine.
Of course, once you open a package of cheese, it will start to degrade more quickly. The USDA recommends consuming opened hard and semisoft cheeses within five to seven days, and opened soft cheeses within three to four days. So if you’re not planning on using that hunk of brie anytime soon, it’s best to keep it sealed up tight!
Can Unopened Cheese Be Left Out?
Yes, unopened cheese can be left out. Cheese is a dairy product made from milk and typically has a high fat content. Because of this, it is slow to spoil but will eventually go bad if left out for too long.
The time that unopened cheese can be left out depends on the type of cheese as well as the temperature it is stored at. For example, hard cheeses like cheddar can last for several weeks at room temperature, while softer cheeses like feta should only be left out for a few days. If the weather is hot, it’s best to err on the side of caution and not leave any cheese out for more than two hours.
Does Unopened Cheese Need to Be Refrigerated?
Most cheeses need to be refrigerated in order to keep them fresh and prevent spoilage. However, there are a few exceptions to this rule. Unopened hard cheese, such as Parmesan or cheddar, can be stored at room temperature for several months without going bad.
Soft cheese, on the other hand, will only last a week or two unrefrigerated.
If you’re not sure whether a particular cheese needs to be refrigerated, it’s always best to err on the side of caution and store it in the fridge. Once opened, all cheeses should be wrapped tightly and kept in the coldest part of the fridge (usually the back) to prolong their shelf life.
How Long Does It Take for Cheese to Spoil Unrefrigerated?
Assuming you are talking about hard cheese, it can last for weeks or even months unrefrigerated. The main thing that will cause it to spoil is if it gets too warm or if there is too much moisture in the air. If either of those things happen, mold can start to grow on the cheese.
How Long Can Cheddar Cheese Go Unrefrigerated?
Cheddar cheese can go unrefrigerated for up to two hours, as long as it is kept in a cool, dry place. After that time, bacteria will start to grow and the cheese will spoil. If you are going to be keeping the cheese unrefrigerated for longer than two hours, it is best to wrap it tightly in plastic wrap or foil to prevent it from drying out.

Unopened Cheese Left Out
If you’ve ever left a block of cheese out on the counter for too long, you know that it can get pretty stinky. But what if you’ve never opened the cheese? Can unopened cheese go bad?
The answer is yes, unopened cheese can go bad. However, it takes quite a while for this to happen. Unopened hard and semi-hard cheeses will last for several weeks or even months before going bad.
So if you accidentally leave an unopened block of cheddar out overnight, don’t worry – it will still be edible.
Of course, once you’ve opened a block of cheese, it will start to spoil more quickly. Once opened, hard and semi-hard cheeses should be consumed within a week or two.
softer cheeses like mozzarella and cream cheese should be eaten even sooner – within 3-5 days of opening.
So there you have it – unopened cheese can go bad eventually, but it takes quite some time. Just be sure to consume any open blocks of cheese as soon as possible for the best taste and quality.
How Long Can Vacuum Sealed Cheese Be Left Out
Vacuum sealed cheese can last for weeks, even months, without being refrigerated. The key is to make sure that the cheese is stored in a cool, dry place. If the cheese is exposed to too much heat or humidity, it will spoil quickly.
Vacuum sealed cheese can be left out at room temperature for up to two weeks. After that, it should be refrigerated.
Unopened Cheese Left Out Overnight
If you’ve ever had cheese that’s been left out overnight, you know it can be pretty rank. But what if you don’t open the cheese until after it’s been sitting out? Is it still safe to eat?
It turns out that unopened cheese is actually more resistant to spoiling than opened cheese. This is because the rind helps to protect the interior of the cheese from bacteria and other contaminants. So if your unopened cheese has been left out at room temperature for a few hours, it should still be fine to eat.
Of course, this doesn’t mean that you can leave your unopened cheese out forever. If it’s been sitting out for days or weeks, it’s probably best to just throw it away. And as always, use your best judgement when it comes to food safety.
If something looks or smells off, don’t take a chance – just toss it!
How Long Can Cheddar Cheese Be Left Out
Cheddar cheese can be left out at room temperature for up to two hours, according to the United States Department of Agriculture. After that, it should be refrigerated. Leaving cheddar cheese out for longer than two hours increases the chance of bacterial growth and foodborne illness.
If you’re not sure how long your cheddar cheese has been sitting out, it’s better to err on the side of caution and throw it away. It’s not worth risking your health for a few slices of cheese!
Conclusion
It turns out that unopened cheese can sit out for a while without going bad. If the temperature is below 40 degrees, it can last up to two weeks. If the temperature is above 40 degrees, it should be consumed within one week.
