How to identify spoiled cheese
Cheese is a beloved dairy product enjoyed by many, but it is perishable and can spoil if not stored properly. Here are some detailed ways to identify spoiled cheese:
Appearance
One of the most noticeable signs of spoiled cheese is a change in colour. Fresh cheese should be white or creamy, while aged cheese may have a darker or yellowish hue. If the original yellow or orange hue fades, or if there are drastic changes in colour such as blue, green, black, or white spots, the cheese has likely spoiled.
Texture
Spoiled cheese may also exhibit changes in texture. If your cheese has become slimy, sticky, gritty, or developed a grainy or crumbly texture, it may be spoiled.
Smell
A strong, pungent, or unpleasant odour is another indicator of spoiled cheese. If your cheese smells like ammonia, sulfur, or acetone, it may have bacterial growth or breakdown of proteins or fats. Trust your sense of smell and discard the cheese if it smells off.
Taste
Spoiled cheese may taste bitter, acidic, or unpleasantly sour due to excessive fermentation.
It is important to note that not all spoiled cheese is unsafe to eat, but it is always better to err on the side of caution and discard any cheese that you suspect may be spoiled. Proper storage, such as keeping cheese in the refrigerator and tightly wrapped, can help prevent spoilage.

The health effects of consuming spoiled cheese
Consuming spoiled cheese can have several negative health effects, primarily impacting the digestive system. The severity of symptoms will depend on factors such as the type and amount of cheese consumed, as well as individual susceptibility to foodborne illnesses.
Spoiled cheese is often affected by harmful mould, such as black mould, which can cause allergic reactions in some individuals. These reactions may include respiratory problems. In addition, the consumption of spoiled cheese can lead to gastrointestinal discomfort, loose stools, and in more severe cases, fever and chills. The cheese may taste overly bitter or sour, or have a musty quality, indicating spoilage. It is important to note that even a small amount of spoiled cheese can cause indigestion or other adverse effects, especially if consumed by individuals with compromised immune systems.
Mouldy cheese, in particular, poses health risks. While some moulds are integral to the flavour and texture of certain cheeses, such as Blue Cheese and Camembert, other types of mould can indicate spoilage and compromise the taste and safety of the cheese. The U.S. Department of Agriculture (USDA) advises against consuming food covered in mould due to the potential presence of harmful bacteria. However, in certain situations, the USDA suggests that hard cheeses with minimal mould growth can be salvaged by cutting away the mouldy portion and re-covering in clean wrap.
To avoid the health risks associated with spoiled cheese, it is important to practise proper storage and handling. This includes storing cheese in a sealed container in the refrigerator, maintaining optimal temperature and humidity levels, and periodically checking the expiration date. If in doubt about the quality of the cheese, it is best to discard it rather than risk potential health complications.
If you experience any adverse symptoms after consuming spoiled cheese, it is recommended to seek medical attention immediately.

The storage requirements of cheese
Cheese is an inherently safe product due to its fermentation, which inhibits the growth of foodborne pathogens. However, proper storage is necessary to prevent spoilage and potential foodborne illnesses.
When storing cheese, temperature and humidity are crucial factors. An environment that is too humid and hotter than 45 degrees Fahrenheit (7.2 degrees Celsius) promotes the growth of harmful bacteria and mould. Therefore, it is recommended to store cheese in the refrigerator, specifically in the vegetable crisper or cheese drawer, where the temperature is cold and stable. Unopened cheeses can be kept almost anywhere in the refrigerator, provided they are in a sealed container.
Different types of cheese have varying storage requirements. Soft and semi-soft cheeses, such as goat, Camembert, and Brie, have a high moisture content and should be placed in a resealable plastic container in the crisper drawer. Fresh cheeses like mozzarella or feta should be left in their original packaging, with the water changed every couple of days, and can last between 7 to 10 days in the fridge.
For storage, cheese paper or specialty cheese storage bags are recommended. These materials allow the cheese to breathe and prevent the buildup of gases like ammonia, which can create unpleasant flavours. Plastic wrap is not ideal as it traps moisture, promoting the growth of undesirable bacteria and hindering the release of gases. Additionally, translucent plastic allows light to pass through, which can oxidize the cheese and create off-flavors. If using plastic wrap, it is recommended to \"face\" the cheese by cutting off the slice in direct contact with the plastic before each use.
While some cheeses may be safely held outside of temperature control, this is determined by water activity and pH measurements. Water activity measures the amount of free water available for microbial growth, with lower values precluding the growth of certain microorganisms. pH also plays a role in inhibiting or promoting microbial growth.

The types of mould that are safe on cheese
It is important to note that mouldy cheese, like other mouldy foods, should be discarded. While most moulds are not harmful, they can negatively impact the flavour and texture of the cheese. Additionally, spoiled cheese can be affected by harmful mould, such as black mould, which may cause an allergic reaction or severe food poisoning. Therefore, it is generally recommended to cut off at least an inch around and below the mould spot if you choose to consume mouldy cheese.
Now, coming to the specific types of mould that are considered safe on cheese:
Penicillium: This is one of the most common types of mould used in cheesemaking, particularly for blue cheeses like Gorgonzola, Roquefort, and Stilton. Penicillium mould cultures are added to the cheese during production and contribute to the characteristic flavour and texture of these cheeses.
Geotrichum: This mould is often found on soft-ripened cheeses, such as Camembert and Brie. It gives these cheeses their fluffy, edible rind and contributes to their creamy texture and flavour.
Debaryomyces: This yeast-like mould is also commonly found on the surface of soft-ripened cheeses. It plays a role in the ripening process and adds complexity to the flavour of these cheeses.
Brevibacterium: This mould is responsible for the distinctive pungent smell and flavour of smear-ripened cheeses like Limburger and certain varieties of Swiss cheese. While its presence may be off-putting to some, it is safe for consumption.
While these types of mould are generally considered safe and are even desirable in certain cheeses, it is important to remember that mould can spread quickly and affect the quality and safety of the cheese. Therefore, it is always recommended to inspect the cheese for signs of spoilage, such as unusual odours or textures, before consumption. Additionally, proper storage conditions, including temperature control and humidity management, are crucial to prevent the growth of harmful mould and bacteria.
