American cheese is a processed cheese made from cheddar or Colby and contains sodium citrate, which prevents separation during pasteurization. Its high level of processing means that it has a long shelf life, but it can still go bad. The shelf life of American cheese depends on its storage conditions, and it should always be kept in the refrigerator. Freezing American cheese can extend its shelf life, but it may become crumbly and lose its meltability. The best indicator of spoilage is the presence of mold, but it can also be identified by a slimy texture or a sour odour.

What You'll Learn
American cheese can be frozen to extend its shelf life
American cheese is a processed cheese made from a combination of cheddar, Colby, or similar cheeses, sodium citrate, and preservatives. It is often sold as individually wrapped slices, which can be kept in their original packaging in the refrigerator for 2–3 weeks.
Freezing is a useful method to extend the shelf life of many foods, including cheese. Freezing American cheese can be done, and it will remain safe to consume indefinitely if kept at a constant temperature of 0°F. However, it is important to note that freezing cheese may alter its texture and flavour. It can become crumbly, grainy, and less meltable, which is a key characteristic of American cheese.
If you choose to freeze American cheese, it is best to use it within six to nine months. Before freezing, trim the cheese into a uniform shape, such as a rectangle or cube, and wrap it tightly. The goal is to reduce oxygen contact, and this can be achieved by using a vacuum sealer, or by wrapping in parchment paper followed by a layer of aluminium foil.
When thawing frozen American cheese, it is best to do so in the refrigerator, where it can be kept for an additional 3–4 days. The texture and flavour changes make it more suitable for cooked dishes like casseroles, sauces, and soups, rather than eating it plain or on a cheese board.

It's best to use frozen American cheese within six to nine months
American cheese is a processed cheese made from cheddar, Colby, or similar, with sodium citrate, which allows the cheese to be pasteurized without separating. It was invented in the 1910s by James L. Kraft, the founder of Kraft Foods. Kraft cheese slices are highly processed and can last a long time without spoiling. However, freezing Kraft cheese slices is not recommended as it can alter their flavour and texture, making them grainy and crumbly and less meltable.
That being said, there is no limit to how long you can keep cheese frozen, and it will remain safe to consume indefinitely if kept at a constant temperature of 0°F. However, it is best to use frozen American cheese within six to nine months as its quality diminishes over time. To maximize the shelf life of sliced American cheese in the freezer, wrap the slices tightly in heavy-duty aluminium foil, plastic freezer wrap, or place them in heavy-duty freezer bags.
When it comes to determining whether American cheese has gone bad, it is important to use your senses. While mould is a clear indicator of spoilage, it is not the only one. Touch and smell can also help you gauge whether the cheese is still safe to consume. If the cheese has a slimy texture or a sour odour, it is best to discard it. Eating expired cheese can lead to food poisoning, as it may expose you to harmful bacteria such as E. coli, Salmonella, and Listeria.
It is worth noting that some people have reported consuming Kraft cheese slices that were a year past their expiration date without any negative consequences. However, this is not recommended as there are risks associated with consuming expired cheese. If you are unsure whether your American cheese has gone bad, it is best to err on the side of caution and dispose of it.

Signs of spoilage include a slimy texture, sour odour, or mould
American cheese is a processed cheese product made from a combination of cheeses such as cheddar and Colby, along with other ingredients like sodium citrate, which gives it a distinctively long shelf life. However, it can still go bad, and it's important to know the signs of spoilage to avoid food poisoning from harmful bacteria such as E. coli, Salmonella, and Listeria.
Signs of spoilage include a slimy texture, a sour odour, or mould. A slimy texture is a clear indicator that your American cheese has gone bad and should be discarded. Similarly, if the cheese has developed a sour or otherwise unpleasant odour, it is no longer safe to consume. While mould on American cheese is less likely due to its anti-mold preservatives, it can still happen. If you spot any mould, it's best to throw the cheese away.
It's important to note that even without these obvious signs of spoilage, American cheese can still degrade in quality over time. Freezing can extend the shelf life of American cheese, but it may affect its texture and meltability, making it crumbly and better suited for cooked dishes. When in doubt, it's always best to err on the side of caution and discard the cheese if you have any concerns about its freshness or potential contamination.
To maximise the shelf life of sliced American cheese, proper storage is crucial. After purchasing, it should be kept refrigerated at all times. Unopened packages can be stored in their original deli wrapping, but once opened, it's best to transfer the cheese to an airtight container or heavy-duty freezer wrap to prevent oxidation and moisture loss.
In summary, while American cheese has a relatively long shelf life, it can eventually spoil. Signs of spoilage include a slimy texture, a sour odour, or the presence of mould. Always use your senses and, if in doubt, discard the cheese to avoid any potential health risks associated with consuming spoiled food.

Properly stored, American cheese will last 2-3 weeks in the fridge
American cheese is a processed cheese made from cheddar, Colby, or similar cheeses, with added sodium citrate, which prevents the cheese from separating when it is pasteurized. This type of cheese, including Kraft Singles, is highly processed and can last a long time. However, it is important to note that proper storage is essential to ensure the cheese remains safe to consume.
When stored properly in the refrigerator, American cheese will typically last for 2 to 3 weeks. It is crucial to keep the cheese refrigerated at all times and to follow the "sell-by" date on the package as a guideline. The cheese may still be safe to consume after the "sell-by" date if it has been stored correctly and shows no signs of spoilage.
To maximize the shelf life of sliced American cheese, it is recommended to keep it in its original unopened deli packaging in the refrigerator. Only open the package when you are ready to use the cheese. Additionally, ensure that the refrigerator temperature is maintained at a safe level to preserve the quality of the cheese.
While American cheese can be frozen to extend its shelf life, it is generally discouraged due to potential changes in flavor and texture. Freezing can affect the meltability of the cheese, making it grainy and crumbly. If you choose to freeze American cheese, wrap the slices tightly in heavy-duty aluminum foil or plastic freezer wrap, or place them in heavy-duty freezer bags. Frozen American cheese will maintain its best quality for about 8 months but can be safely stored indefinitely at 0°F.
It is important to inspect American cheese for any signs of spoilage before consumption. Mold, a slimy texture, or a sour odor indicates that the cheese has gone bad and should be discarded. Trust your senses and, if in doubt, dispose of the cheese to avoid the risk of foodborne illnesses.

The exact shelf life of sliced American deli cheese depends on storage conditions. To maximize its shelf life, it should be kept refrigerated at all times and unopened in its original store packaging. Properly stored, sliced American deli cheese can be refrigerated for 2 to 3 weeks, and it will remain safe to use even if the sell-by date passes during this time.
Freezing is also an option to extend the shelf life of American cheese. When properly wrapped and stored at a constant temperature of 0°F, sliced American deli cheese can be safely frozen indefinitely, although it may become crumbly and lose some of its flavor. It is generally best to use it within six to nine months, and it should be noted that freezing can alter the flavor and texture of the cheese, making it grainy and affecting its meltability.
While American cheese can last a long time, it can still go bad and lead to food poisoning if consumed after it has spoiled. Food poisoning occurs when contaminated, spoiled, or toxic food is consumed, exposing individuals to dangerous bacteria such as E. coli, Salmonella, and Listeria. The most common symptoms of food poisoning include stomach aches, nausea, vomiting, and diarrhea, although most people recover completely within a few days, even without treatment.
Therefore, it is important to use your senses to determine if your American cheese has gone bad. In addition to mold, the clearest indicators of spoilage are touch and smell. If the cheese has a slimy texture or a sour odor, it should be discarded. If you are even slightly unsure, it is best to err on the side of caution and get rid of the cheese.
