Blue cheese crumbles last about a week after opening
Blue cheese is a common cheese variety known for its strong smell and distinct flavour. It is made using Penicillium, a type of mould that gives it its unique taste, smell, and appearance. While the mould in blue cheese is safe to consume, blue cheese can still go bad if not stored properly.
Blue cheese crumbles are a popular choice for topping a salad or making a homemade blue cheese dressing. However, these crumbles can often go bad quicker than a large chunk of blue cheese. When exposed to air, blue vein moulds can continue to grow and even develop microscopic mushroom-type organisms. Therefore, it is important to store blue cheese crumbles properly to ensure they last as long as possible.
To maximize the shelf life of blue cheese crumbles after opening, keep the package tightly sealed. Properly stored, an opened package of blue cheese crumbles will last for about 5 to 7 days in the refrigerator. Consume or freeze the blue cheese crumbles within this time frame, even if the "Best By," "Best if Used By," or "Use By" date has not been reached.
Additionally, blue cheese crumbles should be discarded if left out at room temperature for more than 2 hours, as bacteria grow rapidly at temperatures between 40 °F and 140 °F. To further extend the shelf life, blue cheese crumbles can be frozen. When freezing, double wrap the cheese first in wax or parchment paper, and then in plastic wrap or foil.

Blue cheese can be stored in the freezer for up to 8 months
Blue cheese is a beloved dairy product known for its strong smell and distinct flavour. It is made using Penicillium, a type of mould that is responsible for its unique taste, smell, and appearance. While blue cheese can last a long time when stored properly, its shelf life depends on various factors, including humidity and temperature.
One of the most effective ways to prolong the life of blue cheese is to store it in the freezer. Freezing blue cheese can significantly extend its shelf life beyond the typical three to four weeks of refrigerated storage. When frozen, blue cheese remains safe indefinitely, but its taste and texture may change slightly. For optimal quality, it is recommended to consume frozen blue cheese within eight months.
To ensure the best results when freezing blue cheese, follow these steps:
- Cut the remaining cheese wedge into portions.
- Wrap the cheese wedges or crumbles with wax or parchment paper.
- Cover the paper with plastic wrap or foil to prevent drying.
- Place the wrapped cheese in a plastic freezer bag to protect it from freezer burn.
- Optionally, place the wrapped cheese in an airtight container to prevent it from absorbing other scents or flavours in the freezer.
By properly storing blue cheese in the freezer, you can enjoy its pungent flavour and creamy texture for up to eight months, making it a convenient option for those who want to savour this distinctive cheese.

Fuzzy, grey-black mould spots are a sign of spoilage
Blue cheese is known for its pungent odour, which is often divisive. However, when it comes to blue cheese crumbles, it is important to be vigilant about spoilage as they can go bad quicker than a large hunk of blue cheese. The shelf life of blue cheese crumbles is about one to two weeks after opening, and they should be kept refrigerated at all times. If you intend to keep them longer, they can be stored in the freezer for up to eight months without a significant loss of quality.
Now, onto the mould. The blue-green mould spores in blue cheese are perfectly safe and give it its distinctive character. However, the presence of fuzzy, grey-black mould spots is a clear indication that your blue cheese crumbles have gone bad. This type of mould is drastically different from the desirable blue-green mould and is usually a sign that harmful bacteria have started to grow.
The texture and colour of the mould are important indicators of spoilage. Fuzzy mould, particularly in darker colours like black or grey, is a sure sign that your blue cheese crumbles have spoiled. Additionally, look out for slimy yellow or pink spots, which indicate the growth of yeast. These colours are quite distinct from the desirable blue-green mould and should be easy to identify.
It is also worth noting that the body of the cheese should remain white and creamy, with the blue-green veins retaining their colour. If the overall colour and texture of the cheese have changed significantly, it is best to discard it. Remember, when in doubt, it is always safer to throw out the cheese rather than risk consuming something that could be harmful.
In summary, blue cheese crumbles have a relatively short shelf life, and the growth of fuzzy, grey-black mould spots is a clear indication that they have spoiled. Always trust your senses and, if the cheese looks, smells, or tastes suspicious, it is best to discard it and enjoy your cheese worry-free.

While the mould in blue cheese is safe to consume, it's important to remember that blue cheese can still go bad if not stored properly.
When it comes to blue cheese crumbles, it's important to follow proper storage guidelines to ensure their freshness and safety. Blue cheese crumbles should always be kept refrigerated and the package should remain tightly sealed. With proper storage, an opened package of blue cheese crumbles can last for about 5 to 7 days in the refrigerator.
However, if blue cheese crumbles are left out at room temperature, they can spoil much faster. Bacteria grow rapidly at temperatures between 40 °F and 140 °F. Therefore, it is recommended to discard blue cheese crumbles if they have been left out at room temperature for more than 2 hours.

While blue cheese can last a long time, it is essential to store it correctly to prevent spoilage and ensure food safety.
When stored properly in the refrigerator, blue cheese can last for 3-4 weeks. To maximize its shelf life, it is crucial to keep it refrigerated at all times and tightly sealed.
