Blue cheese is a pungent, salty, and creamy delight, but it can be tricky to know when it's past its prime. Blue cheese does go bad, but it's flexible and can vary in terms of colour and texture. The best way to tell if your blue cheese has spoiled is to smell it. Fresh blue cheese has a strong scent, but it changes as it starts to go bad. If it has an ammonia-like smell, it is probably past its best. Blue cheese should be refrigerated to keep it fresh, and ideally stored in a separate container to prevent cross-contamination. An unopened packet of blue cheese will generally last for about a week to two weeks beyond the printed date. Once opened, it should be consumed within 7-10 days.
Characteristics of Blue Cheese Dip Going Bad
| Characteristics | Values |
|---|---|
| Smell | Fresh blue cheese has a strong scent, but it changes as it starts to go bad. If it has an ammonia-like smell, it is probably spoiled. |
| Color | Fresh blue cheese already has blue or green mold in it. Pay attention to the color of the creamy part of the cheese. If it has turned pink, brown, or yellow, it is no longer safe to eat. |
| Texture | If the surface appears slimy or fuzzy, and there are changes in texture, discard the cheese. |
| Taste | If the blue cheese still smells the same and hasn't changed color, taste it. If it's too strong to enjoy, you should throw it away. |
| Expiration Date | In most cases, blue cheese will remain good for one to two weeks past the expiration date. |
| Storage | Store blue cheese in the fridge, wrapped well, and ensure it can breathe. The best temperature for storage is between 46°F–55°F (or 8°C–13°C). |

Unopened blue cheese dip
Blue cheese is very "flexible" and can vary in terms of colour and texture. It has a distinct smell, often described as similar to old socks, and it is expected to become more salty over time. If it's too salty for your liking, it's best to discard it.
To maximise the shelf life of unopened blue cheese dip, it should be stored in a cool, dry area. If it is commercially packaged, it will usually carry a "Best By", "Best if Used By", "Best Before", or "Best When Used By" date. This date is not a safety date, but the manufacturer's estimate of how long the blue cheese dip will remain at peak quality.
To further extend the shelf life of unopened blue cheese dip, it can be frozen. If blue cheese is kept in the freezer at 0 degrees, it can last indefinitely.

Opened blue cheese dip
Blue cheese is a pungent and salty cheese with a distinct smell and taste. It is safe to eat even if it has been left unopened past its "Best By" date, as this is not a safety date but an estimate of how long the dip will remain at peak quality. However, once opened, it is best to consume the blue cheese dip within 7 to 10 days. If the dip is still fairly fresh and its use-by date is a couple of weeks away, it may last up to two weeks. To maximize the shelf life of opened blue cheese dip, it should be kept refrigerated and tightly covered.
When it comes to determining whether opened blue cheese dip has gone bad, there are several signs to look out for. Firstly, blue cheese naturally has a strong smell, but if it develops an ammonia-like odour, it is likely spoiled. The scent of fresh blue cheese will change as it starts to go bad, so it is helpful to smell it when you first open it so you can detect any deviations.
Secondly, while blue cheese already contains blue or green mould, you should pay attention to the colour of the creamy part of the cheese. If it has turned pink, brown, or yellow, it is no longer safe to eat. However, it is important to note that not all blue cheeses look the same, and some naturally have a pink hue near the rind, which is safe to consume. If you are unsure, you can refer to the brand's website for photos of their cheeses to compare.
Thirdly, changes in texture can indicate spoilage. If the blue cheese appears slimy, fuzzy, or dry and crumbly, it has likely gone bad. Aged cheeses may also develop a small amount of liquid whey inside the packaging, which is normal, but if other spoilage signs are present, it should be discarded.
Lastly, you can usually tell if blue cheese has gone bad by tasting it. Fresh blue cheese has a strong, sharp taste, but as it starts to spoil, it becomes increasingly biting. If it is too strong or salty to enjoy, it is best to throw it away. While consuming a small amount of spoiled blue cheese is typically not harmful, it is advisable to trust your senses and discard the dip if it smells, looks, or tastes suspicious.

Blue cheese dip storage
Blue cheese dip has a distinct smell, and it's normal for it to smell like old socks. However, if the ammonia-like smell becomes very strong, it's a sign that the dip has gone bad. Blue cheese dip can also go bad if it has turned pink, brown, or yellow. The ideal temperature for storing blue cheese dip is between 46°F–55°F (or 8°C–13°C). It should be stored in the fridge, with some breathing room, and away from other foods to prevent the mould from spreading.
To maximise the shelf life of opened blue cheese dip, keep it refrigerated and tightly covered. It should be consumed within 3–4 weeks. An unopened package of blue cheese dip will generally stay at its best quality for about 12–18 months when stored in a cool, dry area.
If you want to keep your blue cheese dip for longer, you can freeze it. Frozen blue cheese will last for about six months. When it comes to leftover blue cheese dip, it will start to dry out after a day or two without a wrap. To prevent this, you can use the foil it often comes in, or opt for cheese wrap, wax paper, or aluminium foil. Place the wrapped blue cheese in a freezer bag or airtight container, but don't squeeze out the extra air.

Blue cheese dip shelf life
The shelf life of blue cheese dip depends on several factors, including storage conditions, packaging, and the presence of preservatives. Here is a detailed guide to help you understand the shelf life of blue cheese dip and how to maximize its longevity:
Unopened Blue Cheese Dip:
The precise answer to the shelf life of unopened blue cheese dip depends mainly on storage conditions. When stored in a cool, dry area, an unopened package of blue cheese dip can generally maintain its best quality for about 12 to 18 months. Some brands may specify a "Best By" or "Best Before" date, but this is not a safety date; the cheese dip can be safely consumed past this date if properly stored and the package is undamaged.
Opened Blue Cheese Dip:
Once the package of blue cheese dip is opened, its shelf life decreases significantly. To maximize the shelf life of opened blue cheese dip, it is crucial to keep it refrigerated and tightly covered. Blue cheese dip that has been continuously refrigerated will typically retain its best quality for about 6 to 9 months. However, it is important to note that the cheese dip's texture, color, or flavor may change after the specified storage time, but it is usually still safe to consume.
Signs of Spoilage:
Identifying spoilage in blue cheese dip is essential to ensure food safety. Here are some signs to look out for:
- Ammonia-like smell: Fresh blue cheese has a strong scent, but as it starts to spoil, the ammonia-like smell becomes more pronounced.
- Color changes: Pay attention to the color of the creamy part of the cheese. If it turns pink, brown, or yellow, it is no longer safe to eat. However, a pink hue around the rind of some blue cheeses is natural and safe.
- Texture changes: If the surface of the blue cheese appears slimy, fuzzy, or excessively dry and crumbly, it is best to discard it.
- Taste changes: If the blue cheese dip has become too salty or bitter, it is likely to have spoiled.
Storage Tips:
To extend the shelf life of blue cheese dip and prevent spoilage, consider the following storage tips:
- Refrigeration: Store blue cheese dip in the refrigerator at a temperature between 40°F and 55°F (or 8°C – 13°C). The crisper drawer can help maintain the optimal temperature.
- Airtight container: Keep the blue cheese dip in an airtight container or well-wrapped to prevent drying out and cross-contamination.
- Separate storage: Store blue cheese dip separately from other foods to avoid mold cross-contamination.
- Freeze for longer storage: If you have a large quantity of blue cheese dip, consider freezing it. Frozen blue cheese can last for up to six months and can be thawed and safely consumed beyond this time frame.

Blue cheese dip gone bad signs
Blue cheese dip can go bad, and there are several signs to look out for to determine if it has spoiled. Firstly, blue cheese is known for its strong, pungent smell, often likened to old socks. However, if the ammonia-like odour becomes much stronger than when it was first purchased or develops a stale smell, it is likely spoiled.
Secondly, examine the appearance of the blue cheese dip. If it looks dry, crumbly, and uneven in colour, with a drying top and grey discoloured mould, it has likely gone bad. However, it is important to note that some blue cheeses naturally develop a pink hue around the rind, which is safe to consume.
Thirdly, taste can be an indicator of spoilage. If the blue cheese dip has become too salty or strong for your liking, it may be past its prime. Fresh blue cheese has a strong, sharp taste, but as it ages and spoils, it can become increasingly biting and overpowering.
Finally, consider the storage conditions and expiration date. Blue cheese dip should be refrigerated and well-wrapped to maximise its shelf life. If it has been left unrefrigerated for more than two hours or past its expiration date, it is advisable to discard it.
