How long does American cheese last in the fridge?
The shelf life of American cheese depends on several factors, including the form it is sold in, the type of cheese, and the storage conditions.
Shelf Life of American Cheese
American cheese can be sold as individual slices or blocks and can be either processed or "real" cheese. Generally, unopened American cheese can be stored in the refrigerator for up to four months, while individual slices should be consumed within two to three weeks of opening to maintain the best taste and quality.
Storage Conditions
Proper storage is crucial for preserving the quality and safety of American cheese. It is recommended to maintain a constant temperature between 35-40°F in the fridge to prevent spoilage. For long-term storage, freezing is an option. Before freezing, wrap individual slices or blocks of cheese with wax paper, cheese paper, or foil, or place them in freezer bags. This helps prevent freezer burn and the absorption of other odours.
Signs of Spoilage
It is important to regularly assess the texture, colour, smell, and taste of American cheese to ensure it is still fresh and safe to consume. Spoiled American cheese may exhibit visual changes such as mold growth, discoloration, dried-out edges, or a slimy surface. An off-smell or altered taste distinct from its typically mild, creamy aroma and flavour are also indicators of spoilage.
Factors Affecting Spoilage
Bacteria, mold, moisture, oxygen exposure, and temperature fluctuations can all impact the shelf life of American cheese. Steady temperature control is crucial, as fluctuations can lead to the growth of spoilage-causing microbes.
Freezing and Thawing
Freezing is an effective method to extend the shelf life of American cheese. When freezing, wrap each slice individually and place them in a freezer bag to protect against freezer burn. For thawing, transfer the frozen cheese from the freezer to the refrigerator and leave it overnight to ensure a gradual process. Rapid thawing at room temperature or using a microwave is not recommended as it can affect the texture and taste.
Health Risks of Consuming Spoiled Cheese
Consuming spoiled American cheese can lead to health risks, including food poisoning and digestive distress, which may result in symptoms such as stomach pain, nausea, or vomiting. Therefore, it is important to store and consume American cheese within the recommended time frames and regularly check for any signs of spoilage.

How long does sliced American cheese from the deli last?
Sliced American cheese from the deli typically lasts for 2-3 weeks in the refrigerator. It is important to keep it wrapped in the deli paper it was originally packaged in. This type of cheese is processed, made from a combination of cheeses like cheddar and Colby, and has a mild flavor and aroma. It is usually light orange in colour and often sold in individual slices, making it a convenient choice for burgers and sandwiches.
To extend the shelf life of sliced American cheese from the deli, it can be frozen. When freezing, it is recommended to wrap the cheese tightly in heavy-duty aluminium foil, plastic freezer wrap, or place it in heavy-duty freezer bags. Frozen in this way, the cheese will maintain its best quality for about 8 months, but it will remain safe to consume beyond this timeframe.
It is important to note that frozen cheese may become crumbly and lose some of its flavour. Therefore, it is best suited for cooked dishes such as sauces, soups, and casseroles.
To determine if sliced American cheese from the deli has gone bad, it is advisable to smell and examine its appearance. If the cheese develops an off odour, flavour, or appearance, or if mould appears, it should be discarded.

How to identify if American cheese has gone bad?
American cheese is a versatile ingredient that can be used in both warm and cold dishes. However, it is important to ensure that the cheese is still safe to consume. Here are some ways to identify if American cheese has gone bad:
Appearance
The presence of mould is a clear indication that the cheese has spoiled. If there is only a small amount of mould on a hard cheese, you may cut off the affected area and a little extra with a clean knife. However, if the entire piece is covered in thick mould, it is best to discard it. Discolouration, such as yellowing or darkening beyond the cheese's normal colour, could also be a sign of spoilage. Additionally, dried-out edges, a slimy or tacky surface, and oil or fat separation may indicate that the cheese has gone bad.
Smell
A sour or unpleasant odour that differs from its typically mild, creamy scent is a cause for concern. Spoiled cheese may smell like spoiled milk, ammonia, or even a refrigerator or freezer. It is helpful to smell the cheese when you first purchase it so that you can identify any changes in scent.
Taste
While tasting is not recommended as a primary test, a sour or unusual flavour will confirm that the cheese is not fit for consumption. Spoiled cheese may taste bitter, acidic, or unpleasantly sour.
Texture
Any sudden or unusual changes in texture can be an indicator of spoilage. Hard cheeses can become brittle and prone to cracking, while soft cheeses can become slimy due to the growth of unwanted bacteria.
Storage and Expiry
Proper storage is critical for maintaining the quality and safety of American cheese. It should be stored in the fridge at a constant temperature between 35-40°F. Once opened, it is recommended to use American cheese within two to three weeks to maintain optimal taste and quality. Always check the manufacturer's label for specific storage instructions and expiration dates, as these provide the most accurate guidance on the cheese's longevity.

How to store American cheese?
American cheese is a type of processed cheese made from a blend of milk, cheese cultures, and emulsifying salts. It is typically sold in slices or blocks and has a mild, creamy flavour. Storing American cheese properly will help to maintain its quality and extend its shelf life. Here are some tips on how to store American cheese:
Choose the Right Storage Container:
Select an airtight container made of glass or plastic that is slightly larger than the cheese block or slices. This will provide enough space for air circulation and prevent the cheese from drying out.
Line the Container with Paper:
Before placing the cheese in the container, line it with a layer of paper. Speciality cheese paper, which has tiny perforations to allow air circulation and prevent drying, is ideal. If you don't have cheese paper, you can use wax or parchment paper.
Store in the Refrigerator:
Place the container with the cheese in the refrigerator. The ideal temperature for storing cheese is around 35 °F (4 °C). Store American cheese separately from other types of cheese to prevent the transfer of flavours and odours.
Change the Paper Regularly:
Every few days, remove the cheese from the container and change the paper lining. This will help to absorb any excess moisture and prevent the growth of unwanted bacteria.
Avoid Using Plastic Wrap:
While plastic wrap can be used as a last resort for a short period, it is not ideal for long-term storage. Plastic wrap does not allow the cheese to breathe properly, leading to the buildup of moisture and undesirable flavours.
Consider Using a Cheese Grotto:
If you are a dedicated cheese lover, investing in a Cheese Grotto or a similar product can be a great option. These containers are designed to maintain the proper humidity and provide an optimal environment for storing cheese.
Handle with Care:
When handling American cheese, use clean utensils and avoid touching the cheese directly with your hands. This will help prevent contamination and the growth of bacteria.
Check for Spoilage:
Regularly inspect the cheese for any signs of spoilage, such as mould, sliminess, or unpleasant odours. If you notice any of these, discard the cheese immediately.
By following these storage guidelines, you can enjoy your American cheese for longer and maintain its optimal flavour and texture.

What is American cheese made from?
American cheese is a processed cheese made from a blend of mild, creamy cheeses, such as cheddar, Colby, Swiss, Jack, and Grana. It can also include other flavour- and texture-enhancing ingredients, such as milk, skim milk, buttermilk, cream, whey proteins, and emulsifying agents.
The process of making American cheese was invented in Switzerland as a way to reduce cheese waste. It involves melting down chunks of cheese with a liquid and an emulsifying agent, such as sodium citrate, which stops the cheese fats from separating. The liquid mixture is then moulded into bricks or slices and packaged.
The term "American cheese" originally referred to traditional but more expensive cheddars made and sold in the US. However, after James L. Kraft, founder of Kraft Foods Inc., patented his manufacturing process for processed cheese in 1916, the term "American cheese" rapidly began to refer to the processed variety.
