How Do You Know if Cheese Is Bad?
To determine if cheese is bad, there are several indicators to look for.
One method is to rely on the smell of the cheese; if a mild cheese smells strong or has a pungent ammonia odor, it should be discarded.
Changes in the cheese’s appearance, such as different colored or textured patches of fuzz, can also suggest spoilage.
Additionally, tasting the cheese can provide clues; if it tastes overly bitter, sour, or musty, it may be bad.
Consuming spoiled cheese can lead to indigestion, allergies, or severe food poisoning, so it is important to seek medical attention if you experience symptoms after eating it.
Proper storage of cheese is crucial in maintaining its freshness, with humidity and temperature being key factors.
Storing opened cheese in a dedicated drawer and using cheese paper or wax paper instead of plastic wrap can help it last longer.
Freezing can alter the texture of creamy cheeses, but hard cheeses freeze and thaw well.
Quick Tips and Facts:
1. Cheese can sometimes develop a blue or green mold on its surface, but not all molds are harmful. While some molds can produce toxins and cause food poisoning, others, like the blue mold found in certain cheeses like Roquefort or Gorgonzola, are actually safe to eat.
2. The sniff test is not always reliable for determining if cheese is bad. While it is commonly believed that a bad smell indicates spoiled cheese, some types, like Limburger or certain washed-rind cheeses, have naturally pungent odors even when they are perfectly fine to consume.
3. When cheese goes bad, it can develop an ammonia-like smell. This smell is caused by a group of bacteria called pseudomonas, which produce a compound similar to ammonia. Although this might be unpleasant, it doesn’t necessarily mean the cheese is harmful, as it is common in aged and well-preserved varieties like Parmesan.
4. Hard cheeses like cheddar or Swiss can still be consumed after trimming off the moldy parts. Unlike soft cheeses, which should be discarded entirely if moldy, hard cheeses can often be salvaged by cutting off the mold at least one inch deep and rewrapping the remaining good portion tightly.
5. While a change in color, texture, or odor can indicate that cheese has gone bad, the most reliable way to tell is by tasting it. If the cheese tastes sour, bitter, or significantly different than usual, it is likely spoiled and should not be eaten.
Cheese Storage And Expiration Dates
When it comes to cheese, proper storage is crucial to ensure its freshness and longevity. Cheese can go bad if it is not stored properly or if it is past its expiration date. It is essential to think of cheese as a living thing, similar to fresh produce, as the cultures and molds in cheese can die and start rotting.
If unopened, a package of cheese can last in the refrigerator for a long time, especially if it’s vacuum-sealed. The best-by dates on the packaging indicate when the cheese will remain good to eat. However, many aged cheeses may still be good even after the best-by date has passed.
The shelf life of different types of cheese can vary significantly. Hard cheeses like cheddar, Parmesan, and Gouda can last the longest, up to six months, while fresher, softer cheeses like cottage cheese and queso blanco go bad more quickly, often within a few weeks. It’s important to consider the moisture content of the cheese as it affects how long it will last once opened.
Factors Affecting Cheese Freshness And Shelf Life
Once opened, the moisture content of the cheese becomes an important factor in determining its freshness. Soft cheeses with high moisture content, like Brie and chèvre, can be breeding grounds for both good and harmful bacteria. These cheeses are more susceptible to going bad rapidly. On the other hand, harder cheeses have less moisture and can last longer.
There is no single answer to how long an opened package of cheese will last, as it depends on the type of cheese and storage conditions. However, as a general guideline, soft cheeses can last in the fridge for about a week once opened, while hard cheeses can last up to a month.
- Soft cheeses with high moisture content are more susceptible to going bad rapidly.
- Harder cheeses have less moisture and can last longer.

How Smell, Appearance, And Taste Indicate Spoiled Cheese
When determining if cheese has gone bad, our senses provide valuable clues. Smell is an excellent indicator of cheese quality and safety. If a mild cheese smells strong, like blue cheese or Limburger, it’s a clear sign it should be thrown away. Bad cheeses may have a strong ammonia smell similar to cat urine, indicating possible spoilage.
Appearance is also important in assessing the condition of cheese. Changes in the cheese’s original appearance, such as the development of different colored or textured patches of fuzz, indicate that the cheese has gone bad and should not be consumed.
In addition to smell and appearance, taste is another factor to consider. A bad cheese may taste overly bitter or sour, or it may have a musty quality. On the other hand, a mild cheese suddenly having more character may also be a sign of spoilage.
To summarize:
- Smell: A strong smell like blue cheese or Limburger, or a strong ammonia smell, may indicate spoilage.
- Appearance: Different colored or textured patches of fuzz indicate the cheese has gone bad.
- Taste: Overly bitter or sour taste, or a musty quality, may suggest the cheese is spoiled.
Health Risks Associated With Consuming Spoiled Cheese
Consuming spoiled cheese can have unpleasant and potentially harmful effects on our health. Spoiled cheese can cause indigestion, allergic reactions, and severe food poisoning. It can lead to gastrointestinal discomfort, loose stools, fever, and chills. If you suspect you have eaten spoiled cheese, it is important to seek medical attention immediately.

Proper Cheese Storage Techniques In The Refrigerator
Storing cheese in the refrigerator requires maintaining the right temperature and humidity. High humidity should be avoided, and the temperature should not exceed 45 degrees Fahrenheit. The deli drawer in the refrigerator is often the best place to store cheese, as it provides the optimal conditions.
Unopened cheese can be stored anywhere in the fridge, but once opened, it should be kept in a dedicated drawer and wrapped in cheese paper or wax paper instead of plastic wrap. This allows the cheese to breathe and prevents excess moisture from building up. Proper storage techniques help maintain the freshness and quality of the cheese for a longer period.
Freezing Cheese: Pros And Cons
While freezing can prolong the shelf life of cheese, it’s worth noting that it can also change the texture. Young, soft cheeses, such as mozzarella and ricotta, can become grainy and crumbly when frozen and thawed. On the other hand, hard cheeses freeze and thaw well.
If you have unopened, vacuum-sealed cheese, it can be stored in the freezer as-is. However, if you have opened cheese, it is important to protect it from freezer burn. This can be done by tightly wrapping the cheese in plastic wrap and foil before putting it in the freezer.
Knowing when cheese has gone bad is essential for the health and enjoyment of cheese lovers. Factors such as cheese type, storage conditions, and odor, appearance, and taste can indicate spoilage. It is crucial to store cheese properly in the refrigerator to maintain its freshness and taste. Freezing cheese can extend its shelf life, but it may alter the texture of certain types of cheese. By following these guidelines, cheese lovers can ensure that their cheese is always fresh and safe to eat.
