Cheese Expiration: How Long Can You Keep Individual Cheese?

Cheese is a versatile and tasty dairy product with a relatively long shelf life. However, it's important to know how long cheese can be safely stored to avoid food poisoning. The shelf life of cheese depends on various factors such as the type of cheese, processing method, packaging date, exposure to heat, storage conditions, and the best-by or sell-by date. Generally, hard cheeses like Cheddar, Parmesan, and Gouda have a longer shelf life due to their lower moisture content, while soft cheeses like Brie and Camembert have a shorter shelf life. Proper storage methods, such as refrigeration and wrapping in porous materials, can extend the shelf life of cheese. It's also crucial to inspect cheese for signs of spoilage, such as mould, discolouration, and changes in texture and smell, before consumption.

Hard cheese can last 3-4 times longer than soft cheese in the fridge

Soft cheeses, such as Brie, Camembert, cream cheese, cottage cheese, and ricotta, are highly perishable and typically last for a few weeks to a couple of months past their "best by" date when refrigerated. However, once opened, soft cheeses should be consumed within one to two weeks.

On the other hand, hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content, which helps extend their shelf life. Unopened hard cheeses can be stored in the fridge for several months to even a year. Once opened, hard cheeses can be safely stored in the fridge for three to four weeks.

It is important to note that the shelf life of cheese can be influenced by various factors, such as the type of cheese, processing method, packaging date, exposure to heat, storage conditions, and the "best by" or "sell by" date. Additionally, proper storage is crucial to maximizing the shelf life of both soft and hard cheeses. Soft cheeses should be wrapped in foil or stored in an airtight container, while hard cheeses should be removed from their plastic packaging and wrapped loosely in breathable material like wax or cheese paper before being placed in an airtight container.

To summarize, hard cheese can indeed last 3-4 times longer than soft cheese in the fridge, thanks to its lower moisture content and consequent resistance to bacterial growth.

Soft cheese should be consumed within 1-2 weeks of opening

To extend the shelf life of soft cheese, it is important to store it properly. Soft cheese should be stored in the refrigerator at a temperature of 40°F or lower. It should be kept in a tightly closed container or wrapped in plastic wrap to keep out moisture and other contaminants.

Even when stored properly, soft cheese will only last for a few weeks in the refrigerator. It is important to regularly inspect soft cheese for signs of spoilage, such as mold, changes in texture, discolouration, or an off smell or taste. If any of these signs are present, the cheese should be discarded.

Practicing proper food safety techniques is important to prevent foodborne illness. While soft cheese may be safe to consume past its printed expiration date, it is still important to monitor it closely for any signs of spoilage.

In summary, soft cheese is a perishable food item that should be consumed within 1-2 weeks of opening and stored properly in the refrigerator to maintain its freshness and safety.

Hard cheese can be stored in the fridge for 3-4 weeks

Hard cheeses like Cheddar, Parmesan, and Gruyere are aged for longer periods and have a distinct, crumbly texture. During the cheesemaking process, most of the whey is removed from the curds, which results in a lower moisture content. They are then either brined to create a hard rind or waxed and aged for between two and 36 months, or even longer.

Hard cheeses are also safe to leave out at room temperature for longer than soft cheeses. The Dairy Farmers of Wisconsin recommend that hard cheeses like cheddar, Parmesan, or Gouda can be left out for up to four hours and then rewrapped and put back in the fridge. However, soft cheeses like cottage or cream cheese, brie, or fresh mozzarella should be discarded if left out for longer than two hours.

When storing hard cheese in the fridge, it's important to remove the cheese from its plastic packaging and wrap it loosely in cheese paper or wax paper before placing it in an airtight container.

Signs of spoilage include a darker colour, harder texture, stronger smell, mould, discolouration, and a sour taste

When it comes to cheese, it's important to remember that 'best-by' or 'sell-by' dates are guidelines for quality, not safety. Cheese often remains safe to eat beyond these dates if stored correctly. However, it's crucial to inspect your cheese for any signs of spoilage to ensure it's safe to consume. Here are some signs of spoilage to look out for:

Darker Colour

The development of dark spots or significant changes in colour, such as yellowing or browning, can indicate that your cheese has spoiled. These colour changes are more likely to occur in harder cheeses, which can develop mould over time if not properly stored.

Harder Texture

Spoiled cheese may exhibit changes in texture, becoming overly dry, crumbly, or slimy. This is a result of the cheese losing moisture and changing texture over time, with harder cheeses being more susceptible to drying out.

Stronger Smell

A stronger or unusual smell can be a sign of spoilage. While some types of cheese naturally have a strong odour, a sour, rancid, or ammonia-like smell indicates that the cheese has gone bad. Trust your senses and refrain from consuming cheese with an unpleasant aroma.

Mould

The presence of mould is a clear sign of spoilage. For blue cheeses, blue-green mould is intentional and safe to consume. However, other types of mould on cheeses like Cheddar or Swiss are not safe. Cut off at least 1 inch (2.5 cm) around and below the mouldy spots and discard them.

Discolouration

Discolouration can manifest as orange, rust red, blue, or green spots on or in the cheese. These spots are distinct against the creamy white of the rind or paste. While some mould on hard cheeses can be cut away, soft cheeses with any mould should be discarded entirely.

Sour Taste

If the appearance and smell of the cheese seem acceptable, but you're still unsure, you can cautiously taste a small amount. If it has an off or sour flavour, it's likely spoiled and should not be consumed. Trust your taste buds to determine if the cheese has developed an unpleasant flavour.

If you have a healthy immune system, eating a small amount of mould is unlikely to cause harm

The shelf life of cheese varies depending on the type of cheese and how it's stored. Hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content, which helps extend their shelf life. They can last for several months and even up to a year when stored in the fridge. On the other hand, soft cheeses such as Brie and Camembert have a shorter shelf life, typically lasting for a few weeks to a couple of months past their 'best by' date when refrigerated.

When it comes to mould, the general rule is that hard cheeses can be salvaged by trimming at least 1 inch (2.5 cm) around and below the mouldy area. This is because hard cheeses have a low moisture content, which prevents the mould from spreading to other parts of the cheese. However, if you have a healthy immune system and accidentally eat a small amount of mould, you are likely to be fine. Nevertheless, it is important to monitor for symptoms of food poisoning, such as vomiting, stomach pain, or diarrhea, as some moulds are more dangerous than others.

Soft cheeses, on the other hand, are more susceptible to mould and should be discarded if mould is present. This includes cheeses like cream cheese, cottage cheese, and ricotta. The mould spores can easily contaminate the entire product, making it unsafe to consume.

It is worth noting that some moulds on cheese are harmless, such as those found in blue cheese. However, other types of mould can contain dangerous toxins and cause food poisoning. To prevent mould from growing on cheese, it is recommended to store cheese in tightly wrapped plastic or airtight containers to limit oxygen exposure.

In summary, if you have a healthy immune system, eating a small amount of mould on hard cheese is unlikely to cause harm. However, it is always better to be cautious and avoid consuming mouldy food if you are unsure. Proper storage and smart buying practices are essential to prevent mould growth and ensure the safety of your cheese.
