Leaving food out overnight is generally not recommended, especially meat and dairy products. Meat and dairy are highly perishable, and leaving them unrefrigerated for extended periods can lead to bacterial growth and food spoilage. This is especially true for soft cheeses and meats like turkey, which have a higher moisture content, making them more susceptible to bacterial growth and faster spoilage. While hard cheeses, like Cheddar or Parmesan, can be left out for longer periods without spoiling, it's generally not advisable to leave them out overnight. So, is it bad to leave turkey and cheese out overnight? The answer is yes; it's not a safe practice and can lead to food safety issues and unpleasant sensory changes.

What You'll Learn
Leaving turkey out to thaw overnight is not recommended
While it may be tempting to leave a large turkey out to thaw overnight, doing so is not a safe option. Instead, it is recommended to plan ahead and use alternative methods to thaw the turkey safely. One option is to place the frozen turkey in the refrigerator to thaw slowly and evenly. This method ensures that the turkey remains at a safe temperature throughout the thawing process. It is important to allow sufficient time for thawing, typically 24 hours of refrigeration for every 4 to 5 pounds of weight.
Another option is to submerge the wrapped turkey in cold water. This method is faster than refrigerator thawing but requires more attention. The turkey should be placed in a leak-proof bag and submerged in cold water, with the water changed every 30 minutes to ensure it stays cold. Using this method, it takes approximately 30 minutes per pound of turkey to thaw.
For those who are short on time, a third option is to use the defrost setting on the microwave. This method requires following the manufacturer's instructions for weight and power level settings. It is important to remove all wrapping and place the turkey on a microwave-safe dish, covering it with a paper towel to absorb any moisture. However, it is worth noting that this method may not result in even thawing, and there may be pockets of ice that need to be addressed before cooking.
While it may be tempting to speed up the thawing process, especially when dealing with a large turkey, it is crucial to prioritise food safety. By using these alternative methods, you can ensure that your turkey is safely thawed and ready for cooking, reducing the risk of bacterial growth and potential foodborne illnesses.

Soft cheeses are more perishable and should be discarded if left out overnight
While leaving cheese out overnight is generally not recommended, harder cheeses like Cheddar or Parmesan are usually safe to eat, even if left out overnight. This is because hard cheeses have a lower moisture content, which means they can sit out for longer without spoiling. However, soft cheeses like Brie, Camembert, or Queso Fresco are a different story.
If you accidentally leave soft cheese out overnight, it is best to err on the side of caution and discard it. While it may look and smell fine, there could be harmful bacteria present that cannot be seen or smelled. Consuming spoiled soft cheese can lead to foodborne illness, which can cause vomiting, diarrhea, and other unpleasant symptoms.
To prevent soft cheese from spoiling, it is important to store it properly. Soft cheeses should be consumed within one week of opening and stored in the refrigerator. To keep them fresh, wrap them tightly in wax paper or parchment paper, then place them in a plastic bag or airtight container. This will help to prevent them from drying out while still allowing them to breathe.

Hard cheeses can be left out for longer, but may spoil after 4 hours
Leaving cheese out overnight can lead to bacterial growth, especially in softer cheeses with higher moisture content. The U.S. Department of Health states that cheese should not be left out at room temperature for more than two hours. However, hard cheeses like Cheddar, Parmesan, Gouda, and Swiss have lower moisture content and can sit out for longer without spoiling.
Hard cheeses can be left out for up to four hours, but it is not recommended to leave them unrefrigerated for longer than this. While they may not pose a health risk after four hours, the quality and taste of the cheese may be impacted. Hard cheeses that have been left out for too long may develop an unpleasant smell, a slimy surface, dark spots, dryness, cracks, or mould. If any of these signs of spoilage are present, the cheese should be discarded.
If hard cheese has been left out for less than four hours, it can be wrapped and returned to the refrigerator. To properly store hard cheese, it should be wrapped tightly in wax paper or parchment paper and then placed in a plastic bag or airtight container. This prevents it from drying out while still allowing it to breathe.
It is important to note that the guidelines for leaving cheese out may vary depending on the specific type of cheese and other factors such as temperature and humidity. Additionally, proper storage and handling of cheese are crucial to maintaining its quality and safety.
Regarding turkey, it is not recommended to leave a turkey out to thaw overnight. Frozen meat thaws from the outside in, and leaving a turkey out overnight can put it at risk for bacteria development. Therefore, it is important to plan ahead and thaw a turkey safely in the refrigerator or using other recommended methods.

Proper cheese storage can impact shelf life
The aging process also significantly impacts a cheese's shelf life. As cheese ages, it loses moisture and becomes firmer, extending its longevity. For example, mature Cheddars aged 12-18 months have stronger flavors and can last longer when stored properly. Proper storage techniques are crucial for maximizing the shelf life of cheese. This includes factors such as temperature, humidity, and packaging. Unopened Cheddar cheese stored at 35-45°F (2-7°C) can last for 6-8 months in the refrigerator. Once opened, it should be consumed within 3-4 weeks and stored in the coldest part of the fridge.
To extend the shelf life of hard cheeses, they can be frozen for longer storage, although this may affect the texture upon thawing. Soft cheeses, on the other hand, are more perishable and should be consumed within one week of opening. They should be stored in the refrigerator and not left out at room temperature for more than two hours, as this can promote bacterial growth. If soft cheeses are left out for longer than two hours, they should be discarded.
Additionally, the type of packaging can impact the shelf life of cheese. Vacuum packaging and modified atmosphere packaging can inhibit the growth of yeast, mold, and other spoilage microorganisms. Proper storage not only helps to extend the shelf life of cheese but also maintains its quality and flavor. Leaving cheese out for too long, especially without proper packaging, can lead to changes in taste, flavor, and texture, as well as the growth of unwanted bacteria. Therefore, it is important to understand the proper storage techniques for different types of cheese to maximize their shelf life and maintain their quality.

Cheese can be frozen to be used later in cooked dishes
Leaving cheese out at room temperature for over two hours may cause bacterial growth, especially in softer cheeses with higher moisture content. Hard cheeses like Cheddar or Parmesan can be left out for longer, but soft cheeses like Brie or Camembert should be discarded after two hours to reduce the risk of foodborne illness.
Cheese can be frozen, but its texture and flavour may change. Hard and semi-hard cheeses like Cheddar, Swiss, and Parmesan can be frozen, but softer cheeses like Brie and Camembert are less suited to freezing due to their higher water and fat content. However, even harder cheeses will experience changes in texture when frozen, becoming drier, crumbly, and potentially mealy.
Freezing cheese can extend its shelf life and reduce waste, making it a convenient option for those who want to stock up on cheese or cut back on food waste. It is best to use frozen cheese within two to three months and to avoid refreezing previously thawed cheese.
When using frozen cheese, it is best to grate, crumble, or melt it, as the changes in texture are less noticeable in cooked dishes. Frozen cheese can be added to sauces, grilled cheese sandwiches, or pizza. For example, shredded mozzarella can be placed directly onto a pizza and will melt in the oven.
Therefore, while cheese can be frozen, it is generally recommended for use in cooked dishes rather than eaten fresh due to the changes in texture that occur during freezing and thawing.
