Cheese is a dairy product, and like milk, it can spoil. Each cheese ages differently and therefore spoils differently, but one sign of spoiled cheese is an off smell. Depending on the type of cheese, this scent can be of spoiled milk, ammonia, or even of a refrigerator or freezer. If a mild cheese, like Monterey Jack or American, starts to smell strong, like blue cheese or Limburger, then it's time to throw it away. Spoiled cheese can cause severe food poisoning, so it's important to be able to identify when it has gone bad.

Spoiled milk can be used to make homemade cheese
Spoiled milk is typically characterised by an unpleasant odour and taste, as well as changes in texture, caused by an overgrowth of bacteria. Drinking spoiled milk is not recommended as it may cause food poisoning, resulting in digestive issues such as stomach pain, nausea, vomiting, and diarrhoea. However, spoiled milk can be utilised in various ways, including the creation of homemade cheese.
Making cheese from spoiled milk is a straightforward process. Begin by slowly heating the spoiled milk in a pot over low to medium heat. Once it reaches a boil, reduce the heat and add a mixture of sour cream, eggs, and salt. Stir the mixture continuously until small white clumps form, indicating that the milk protein is separating from the whey, or in other words, the milk is curdling. Leave the pot on the stove for an additional 10 to 15 minutes, stirring constantly.
The next step is to separate the milk protein from the whey. Remove the pot from the heat, place a wet cheesecloth in a sieve, and pour the contents of the pot through the cloth. Collect the whey, which can be used as a brine to preserve the freshness of the cheese. Wrap the cheesecloth tightly around the milk protein and squeeze out any remaining liquid. Allow the wrapped cheese to cool at room temperature before placing it in the refrigerator for at least four hours.
The final product is a delicious homemade cheese that can be served and enjoyed. It is best to store the cheese in an airtight container in the refrigerator, where it will keep for about a week to ten days. This process not only creates a tasty treat but also helps reduce food waste by utilising spoiled milk.
While spoiled milk can be used to make homemade cheese, it is important to exercise caution. If the milk has started to curdle, become slimy, or grow mould, it is best to discard it. Additionally, the decision to consume cheese made from spoiled milk should be made with caution and a thorough understanding of the risks involved.

Spoiled milk is caused by an overgrowth of bacteria
The pasteurisation process kills many harmful bacteria, but some strains may survive and cause spoilage. These bacteria are not considered health-promoting and could cause food poisoning, resulting in digestive symptoms like stomach pain, nausea, vomiting, and diarrhoea. However, spoiled milk can be used in cooking and baking, as the heat involved in these processes neutralises the harmful effects of the bacteria.
Cheese, being a dairy product, can also spoil, and one sign of spoilage is an "off" smell, which could be similar to spoiled milk. Other indicators of spoilage include changes in colour, texture, or consistency, such as surface mould, sliminess, oil, or bloated packaging. It is natural for cheese to develop surface mould, and small amounts can be trimmed off without affecting the rest of the cheese.
To prevent milk spoilage, it is important to maintain temperatures below 40 °F (4 °C) and avoid exposure to light. Milk should be stored at the back of the fridge to avoid frequent temperature changes and reduce spoilage. Proper storage can help extend the usable life of milk.

Spoiled milk has a distinct unpleasant odour
Drinking spoiled milk can cause food poisoning, resulting in digestive issues such as stomach pain, nausea, vomiting, and diarrhoea. Even a small sip of spoiled milk is unlikely to cause harm, but it is still not recommended to drink it in moderate or large quantities. If the milk has started to curdle, become slimy, or grow mould, it is best to discard it.
However, spoiled milk can still be used in various ways, such as in culinary recipes or cosmetic applications. For example, it can be used to make homemade cottage cheese, tenderize meat, or as a skin softener in face masks or baths. Using spoiled milk in recipes is a great way to reduce food waste.
When it comes to cheese, the sense of smell is one of the best ways to determine if it has gone bad. If a mild cheese, such as Monterey Jack or American, smells strong like blue cheese or Limburger, it should be discarded. Cheeses that are naturally pungent, like blue cheese or Camembert, will have a strong ammonia smell once they have spoiled.
It is important to note that different cheeses age and spoil differently, and some cheeses may have a strong or pungent smell even when they are not spoiled. Therefore, it is recommended to smell the cheese when it is first purchased to establish a baseline for its normal scent. Other indicators of spoilage in cheese include changes in appearance, such as mould, colour changes, or alterations in texture, such as sliminess or oil. If all else fails, tasting a small piece of the cheese can help determine if it has gone bad, but this should be a last resort as consuming spoiled cheese can cause gastrointestinal issues and, in severe cases, food poisoning.

Spoiled milk can cause food poisoning
Spoiled milk is caused by an overgrowth of bacteria that compromises the quality, flavour, and texture of milk. The pasteurization process kills many of the most harmful strains of bacteria known to cause foodborne illness, including E. coli. However, even pasteurized milk can spoil if it is not constantly refrigerated.
Drinking spoiled milk is not recommended, as it can cause food poisoning, resulting in uncomfortable digestive symptoms such as stomach pain, nausea, vomiting, and diarrhea. The risk of food poisoning and the severity of digestive distress increase with the quantity of spoiled milk consumed. However, accidentally ingesting a small sip of spoiled milk is not likely to cause harm. If the milk is very old and has started to curdle, become slimy, or grow mold, it should be discarded.
While spoiled milk should not be consumed as a beverage, it can still be used in various culinary applications. It can be substituted for regular milk, buttermilk, yogurt, or sour cream in baked goods such as biscuits, pancakes, scones, and cornbread. It can also be used to tenderize meat or added to soups, casseroles, or salad dressings. Using spoiled milk in recipes is a great way to reduce food waste.
When it comes to cheese, determining whether it has gone bad can be more challenging. Each type of cheese ages and spoils differently, and some cheeses naturally have a pungent or "off" smell. The best way to assess whether a cheese has spoiled is to smell it when it is first purchased to establish a baseline for its unique scent. Other indicators of spoilage include changes in colour, consistency, texture, or the presence of surface mold, sliminess, oil, or bloated packaging. If in doubt, it is best to discard the cheese, especially if it exhibits multiple signs of spoilage.

Spoiled milk can be used in cosmetic applications
Spoiled milk is typically characterised by an unpleasant sour smell, curdling, and sometimes a yellowish colour. This occurs due to bacterial growth after milk's expiration date. While it is not advisable to drink spoiled milk, it can be used in cosmetic applications.
Spoiled milk can be used as a natural exfoliant in skincare routines. The lactic acid in spoiled milk helps to slough away dead skin cells and promote a brighter complexion. If you find the smell off-putting, you can add a few drops of essential oil to mask it. This is a great way to repurpose spoiled milk and reduce waste.
To test if your milk is spoiled, give it a sniff. If the smell is bearable and the taste is somewhat regular with a hint of sourness, then it might be suitable for repurposing. However, if the milk smells rancid or has large curdles, it is best to discard it. Another test is to heat a small amount in the microwave; if it curdles immediately, it is spoiled.
It is important to note that consuming spoiled milk can pose health risks due to bacterial contamination, potentially leading to food poisoning. Therefore, it is crucial to exercise caution and ensure that the milk is only slightly spoiled before using it in cosmetic applications.
