The shelf life of cheese varies depending on the type of cheese and how it's stored. Hard cheeses like Cheddar, Parmesan, and Gouda tend to have a longer shelf life, even beyond their 'best by' date, if they are stored properly and show no signs of spoilage. Soft and fresh cheeses have a shorter shelf life and are more perishable. While there are no regulations or laws mandating date marking on cheese, it's important to use your judgment and look for signs of spoilage, such as mould, off colours, odd odours, or changes in texture, before consuming cheese past its expiration date.
| Characteristics | Values |
|---|---|
| Expiry Dates | In the US, there are no regulations on date marking when it comes to cheese. Expiry dates are often arbitrary and a guideline for quality rather than safety. |
| Safe Consumption | Cheese can often be safely consumed past its expiry date, provided it is stored properly and shows no signs of spoilage. |
| Storage | Hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content and longer shelf life. They should be stored in the fridge, ideally below 40°F, to extend their shelf life. |
| Spoilage Signs | Mould, odd odours, slimy texture, sour flavour, discolouration, and unusual textures are signs of spoilage. For hard cheeses, also check for squashy spots, ballooning of packaging, and rancid smells. |
| Soft Cheeses | Soft cheeses like Brie, Camembert, and Mozzarella have a shorter shelf life, typically lasting a few weeks to a couple of months past their expiry date when refrigerated. |
| Fresh Cheeses | Fresh cheeses like cream cheese, ricotta, and cottage cheese are highly perishable and usually last only a few weeks past their expiry date when refrigerated. |
| Shredded Cheese | Hard shredded cheeses like Parmesan and Swiss should be eaten within a month of opening. Soft shredded cheeses like Cheddar and Mozzarella will only last for one to two weeks after opening. |

Hard cheeses like Cheddar, Parmesan and Gouda can be good past their expiration date
Hard cheeses like Cheddar, Parmesan, and Gouda can be good past their expiration date if they are properly stored and show no signs of spoilage. These cheeses have a lower moisture content, which helps extend their shelf life. Hard cheeses that haven't been opened can last for several months and even up to a year when stored in the fridge.
Naturally aged hard cheeses like Cheddar can continue to age and sharpen in your fridge if stored properly in an unopened package below 40°F. However, it's important to note that once these hard cheeses are opened, exposure to air and potential bacterial contamination cause their shelf life to decline significantly.
It's important to use your judgment and consider the type of cheese, as well as its appearance, odour, and taste before consuming it. If you're unsure, it's safer not to eat it. Some signs of spoilage to look out for include mould, odd odours, a slimy texture, or a sour flavour. If there is mould on hard cheese, you can cut off the mouldy part and safely eat the rest. However, if you find mould on soft cheese, it's recommended to throw away the entire product.
People with compromised immune systems, pregnant women, elderly individuals, or those with certain health conditions should be more cautious and avoid consuming foods that show any signs of spoilage.

Soft cheeses like Brie and Camembert have a shorter shelf life
The shelf life of cheese varies depending on the type of cheese, the processing method, the packaging date, its exposure to heat, and how it is 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 like Brie and Camembert have a shorter shelf life.
Soft cheeses are highly perishable and typically last for a few weeks to a couple of months past their 'best by' date when refrigerated. Fresh cheeses like cream cheese, ricotta, and cottage cheese fall under this category and usually last only a few weeks past their 'best by' date. Soft cheeses have a high moisture content, creating an environment where bacteria can grow more rapidly. Therefore, most soft cheeses should be eaten within a week of purchase.
It is important to note that the 'best before' or 'sell by' dates on cheese are guidelines for quality rather than safety. Cheese often remains safe to eat beyond these dates if stored properly. However, soft cheeses are more susceptible to spoilage, and any sign of mold is an indication that the entire product should be discarded.
To extend the shelf life of soft cheeses, proper food storage is crucial. One way to reduce airflow and maintain some ventilation is to store soft cheeses in a Tupperware container or plastic jar. Additionally, properly storing cheese in plastic wrap can help inhibit mold growth. However, molds can tolerate refrigeration temperatures, so it is important to inspect soft cheeses before consuming them.
In summary, soft cheeses like Brie and Camembert have a shorter shelf life compared to harder cheeses. To ensure food safety, it is recommended to practice proper hygiene and food safety techniques, especially for those with compromised immune systems, pregnant women, elderly individuals, or those with certain health conditions.

Fresh cheeses like cream cheese, ricotta and cottage cheese are highly perishable
Fresh cheeses like cream cheese, ricotta, and cottage cheese are highly perishable and have a shorter shelf life compared to harder cheeses. When stored in the refrigerator, they usually last only a few weeks past their 'best-by' date. If opened, their shelf life is even shorter, and they are best consumed within one to two weeks.
It is important to note that the ''best-by' date is a guideline for quality rather than safety. Fresh cheeses can sometimes go bad before this date due to quality control issues during manufacturing or improper storage. Therefore, it is always good to inspect your cheese for signs of spoilage, regardless of the date.
Signs of spoilage in cheese include mould, off colours, unusual textures, and unpleasant odours. If you notice mould on hard cheeses like Cheddar or Swiss, cut off at least 1 inch (2.5 cm) around and below the affected areas before consuming the rest of the cheese. However, if mould is present on soft cheeses or bread, it is recommended to discard the entire product.
Additionally, consider your own health condition when consuming cheese past its 'best-by' date. If you have a compromised immune system, are pregnant, elderly, or have certain health conditions, it is generally advisable to be more cautious and avoid consuming foods that show any signs of spoilage.
To extend the shelf life of fresh cheeses, proper storage is crucial. Keep them in the refrigerator, and maintain a temperature below 40°F (4°C) to prevent bacterial growth. Additionally, wrap blocks of cheese in wax, parchment, or cheese paper for added protection.

Signs of spoilage: mould, odd odours, slimy texture, sour flavour
Mould is one of the most common signs of cheese spoilage. While mould growth on hard cheeses can be remedied by cutting off the mouldy section, the entire product should be discarded if it is a soft cheese.
Odd or rancid odours are another indicator of cheese spoilage. This occurs when cheese undergoes bacterial or microbial breakdown, releasing free fatty acids and specific volatile compounds that result in an off-putting smell.
A slimy texture in cheese is often indicative of spoilage caused by specific bacteria. Slime production by lactic acid bacteria and other bacteria such as Alcaligenes viscolactis and Pseudomonas putida has been observed in certain cheese varieties, contributing to an undesirable texture.
A sour flavour in cheese is a sign of spoilage caused by excessive fermentation. This occurs due to the overgrowth of bacteria, resulting in a strong, sour taste that deviates from the typical flavour profile of the cheese.
In addition to these signs, it is important to look out for other indicators of cheese spoilage, such as colour changes, the presence of noticeable squashy spots, and sudden ballooning of the packaging. Trust your senses and use good judgement when assessing the edibility of cheese past its expiration date.

Best-before dates are guidelines for quality, not safety
It is important to understand that best-before dates are more about quality than safety. Food products are safe to consume past the best-before date on the label, but the quality of perishable products may deteriorate. Food banks, charitable organisations, and consumers should evaluate the quality of the product before consumption to determine whether there are noticeable changes. This evaluation is especially important for people with compromised immune systems, pregnant women, the elderly, or those with certain health conditions.
The "Best if Used By/Before" date indicates when a product will be at its best flavour or quality. It is not a purchase or safety date. Similarly, a "Sell-By" date is not a safety date but tells the store how long to display the product for sale for inventory management. A "Use-By" date is the last date recommended for using the product while at peak quality, and it is not a safety date except when used on infant formula. Freezing acts as a "pause" button on food, and if done correctly, food will not deteriorate or spoil as bacteria cannot grow.
While best-before dates are not an indicator of safety, it is still important to be cautious. Food that is mishandled before or after the date on the package can quickly multiply bacteria, including pathogenic bacteria that can cause foodborne illness. For example, cold chicken salad left out at temperatures higher than 40 degrees F (4.4 degrees C) for more than two hours should not be consumed. Other examples of mishandling include improper defrosting or poor sanitation practices.
When it comes to cheese specifically, hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content, which helps extend their shelf life. These types of cheese can last for several months to even a year or more past their 'best by' date when stored properly in the fridge. Blue cheeses like Stilton, Roquefort, and Gorgonzola can also have a longer shelf life of several months when unopened and refrigerated properly. On the other hand, soft and fresh cheeses have a shorter shelf life and are more perishable. Unopened soft cheeses like Brie and Camembert can last for a few weeks to a couple of months past their 'best by' date when refrigerated. Fresh cheeses like cream cheese, ricotta, and cottage cheese are highly perishable and usually last only a few weeks past their 'best by' date in the refrigerator.
In summary, best-before dates are primarily guidelines for quality rather than safety. Food products, especially those properly stored, are often safe to consume beyond these dates, but consumers should carefully evaluate the quality and look for signs of spoilage before consumption.
