Blue cheese is a pungent, divisive dairy product with a long shelf life. It can be kept in the fridge for up to a month, or in the freezer for up to six months. However, once opened, it should be consumed within a week. Blue cheese can go bad, and the signs of spoilage are similar to those of other cheeses: an unusual smell, discolouration, and slime. If the cheese has been left unrefrigerated for more than two days, it should be discarded. Blue cheese dressing can also go bad, and the same rules apply: an unusual smell, discolouration, and slime are all signs that it has expired.

What You'll Learn
Blue cheese dip shelf life
Firstly, let's consider the blue cheese itself. Blue cheese is a unique variety of cheese that contains edible mould, giving it a pungent taste and scent. This mould requires air to thrive, so blue cheese is typically packaged with tiny holes in the wrapping. When storing blue cheese, it is important to replicate these conditions by using perforated wrapping or placing it in a container that allows it to breathe.
The shelf life of blue cheese also depends on how it is stored. It should be kept in the fridge, preferably on the bottom shelf or in a drawer, as this is usually the coldest part of the refrigerator. Blue cheese should be wrapped or placed in an airtight container to prevent it from drying out and to avoid cross-contamination and odour absorption. With proper storage, an unopened package of blue cheese can last for about a week to two weeks beyond the printed date on the label. Once opened, it will retain its best quality for about 7 to 10 days but may keep for longer if well wrapped and not nearing its original expiry date.
Now, let's discuss the blue cheese dip. If the dip contains additional ingredients such as mayonnaise, sour cream, or yoghurt, these may impact its shelf life. However, assuming the dip is primarily made of blue cheese and stored properly in the refrigerator, it should stay fresh for a similar duration as the cheese itself.
To maximise the shelf life of blue cheese dip, it is important to follow good hygiene practices. Avoid dipping food directly into the container, as this can introduce bacteria and cause the dip to spoil faster. Instead, pour or scoop out the desired amount and store the rest in the refrigerator. Additionally, always check the dip for any signs of spoilage before consuming it. Look for mould, discolouration, or changes in texture. If the dip has an ammonia-like smell or a strange taste, it is best to discard it.
In summary, blue cheese dip can be enjoyed for about a week to two weeks beyond the printed date on the label if stored properly. However, it is important to regularly inspect the dip for any signs of spoilage and to practise good hygiene when handling and consuming it.

Signs of spoilage
Blue cheese is known for its pungent taste and scent, and its unique blue or green mold. However, it can still go bad, and knowing how to spot spoilage is important for food safety. Here are the signs to look for:
Changes in Odor
The best way to tell if blue cheese has spoiled is by its smell. Fresh blue cheese has a strong, sharp scent, but this changes as it starts to go bad. If the cheese has developed an ammonia-like smell, it is likely that it has spoiled. An ammonia smell is produced by the same bacteria that cause the cheese to liquify as it putrefies. If the cheese smells "funny", sour, or foul, it should be discarded.
Changes in Color
The creamy part of the blue cheese, which is normally white, beige, or yellow, can change color when it spoils. If it turns pink, brown, or green, it should be thrown away. Browning is a serious sign of spoilage and is often accompanied by an off-odor and a change in texture. Yellowing can indicate that the fats in the cheese have separated, which may not be harmful, but it is best to err on the side of caution and discard the cheese.
Changes in Texture
If the surface of the blue cheese appears slimy or fuzzy, it should be discarded. This change in texture can indicate the presence of bacteria or mold, which may be harmful.
Changes in Taste
If the blue cheese still smells and looks the same, a small taste can indicate whether it has spoiled. Fresh blue cheese has a strong, sharp taste, but as it ages, it becomes increasingly biting and strong. If it is too strong to enjoy, it should be thrown away. However, it is important to note that eating spoiled blue cheese is generally not dangerous, and a small taste is unlikely to make you sick.

Proper storage
Firstly, it is crucial to keep blue cheese refrigerated. The colder it is, the longer it will stay fresh. Therefore, it is recommended to store it on the bottom shelf of the refrigerator, as this area is typically the coldest. If your refrigerator has drawers at the bottom, that is the ideal storage location, as the temperature will remain stable.
Secondly, blue cheese should be stored in an airtight container or wrapped properly. The original packaging of blue cheese often has tiny holes to allow the cheese to breathe, as the mold in blue cheese requires air to thrive. However, when storing leftovers, it is best to use a freezer bag or an airtight container to prevent odor absorption and cross-contamination. Ensure that the cheese is not wrapped too tightly, allowing some space for it to breathe.
Additionally, if you are storing a small container of blue cheese dip, it is essential to follow proper food safety practices. Always use clean utensils when handling the cheese dip to avoid introducing bacteria. If you have dipped food directly into the container, the dip may go bad sooner, so it is advisable to scoop out the desired amount and store the rest separately.
By following these storage instructions, you can maximize the freshness and quality of your blue cheese dip while preventing it from going bad prematurely.

Freezing blue cheese dip
Blue cheese dip can be frozen, but it is not recommended due to the potential change in texture and consistency. The dip's creamy and smooth texture, which is key to its appeal, may not be retained after freezing and thawing. This is because the dairy components can separate when frozen and then thawed, resulting in a grainy or watery consistency.
However, if you are willing to compromise on texture for longevity, freezing is an option. To freeze blue cheese dip, follow these steps:
- Ensure the dip is at room temperature and that there are no leftover food bits.
- Transfer the dip to a freezer-safe container or a resealable bag, leaving an inch of space at the opening to allow for expansion.
- Label the container or bag with the date and store it in the freezer.
When freezing blue cheese dip, it is important to consider the ingredients and their response to freezing. The high moisture content in the dairy components and the presence of live cultures in yogurt can be sensitive to freezing temperatures. Additionally, freezing and thawing may alter the emulsion of the dip, leading to separation or a change in texture.
It is worth noting that freezing blue cheese individually and then thawing it before adding it to a dip recipe is an option. This can help extend the shelf life of the blue cheese and ensure it does not go bad.
To maximize the shelf life of blue cheese dip, it is recommended to store it in the refrigerator, tightly covered. It will generally stay at its best quality for about 6 to 9 months when continuously refrigerated.

Blue cheese dip health risks
Blue cheese is a popular condiment in the US, often used as a salad dressing or as a dip for vegetables and Buffalo wings. It is made using a type of mould called Penicillium roqueforti. While the mould is non-toxic and safe for human consumption, blue cheese can still go bad.
If blue cheese is left unrefrigerated for too long, or if it is refrigerated but not consumed within several weeks, the mould can produce toxic compounds called mycotoxins, which can cause short- and long-term health effects. Therefore, it is important to store blue cheese properly and consume it within a few weeks of opening.
In addition, blue cheese has a high sodium, calorie, and fat content. Excess calories can lead to weight gain, and the high levels of saturated fat can increase cholesterol levels and the risk of heart disease. As such, overconsumption of blue cheese can be harmful and should be avoided.
To ensure food safety, it is important to check for signs of spoilage before consuming blue cheese. The best way to tell if blue cheese has gone bad is to smell it. Fresh blue cheese has a strong scent, but as it starts to spoil, it will develop an ammonia-like smell. If the cheese has changed colour, this is another sign that it has gone bad. If there are patches of grey or black mould that look fuzzy, the cheese should be discarded.
