Blue cheese is a type of cheese that is known for its strong smell and distinct flavour.

If it smells like ammonia, this is also a sign that it has gone bad. If you are unsure, it is best to throw it away as consuming spoiled blue cheese can cause food poisoning.

What You'll Learn
Blue cheese can be stored in the fridge for 3-4 weeks
Blue cheese is a pungent variety of cheese with a strong scent and sharp taste. It contains an edible mold that gives it its distinctive flavour and smell. While it can be safely stored in the fridge for 3-4 weeks, it's important to know how to identify if it has gone bad.
Blue cheese, like any other cheese, can spoil, and knowing how to spot this is essential for food safety. The first sign of spoilage is usually a change in 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 likely spoiled and should be discarded. The ammonia smell is produced by the blue mold in the cheese, which reduces the acidity over time. This reduction in acidity allows other things to grow on the cheese, causing it to spoil.
Another way to tell if blue cheese has gone bad is to examine its appearance. The creamy part of the cheese should be white or beige. If you notice any discolouration, slime, or fuzziness, it is best to throw away the entire piece, as bacteria or mold may still be present. Additionally, check the expiration date on the packaging if available.
It is worth noting that blue cheese should be refrigerated at all times to maintain freshness. Proper storage can extend the shelf life of blue cheese. Storing it in the bottom section of the fridge, preferably in a drawer, can help maintain a stable temperature. Additionally, keeping the package tightly sealed is essential to maximize its shelf life.

It can be frozen to extend its shelf life
Blue cheese is a semi-soft cheese that can go bad if not stored properly. To extend its shelf life, it is advisable to store it in the refrigerator, preferably in a tightly sealed container or wrapped in wax paper or foil. If you want to extend its shelf life even further, you can freeze it.
Freezing blue cheese is a great way to preserve it for longer. Frozen blue cheese can last for several months in the freezer.

To freeze blue cheese, start by cutting it into smaller portions if you have a large wedge. Wrap each portion tightly in plastic wrap or place it in an airtight container. Then, put the wrapped cheese in a freezer bag and seal it well before placing it in the freezer.
In addition to extending the shelf life, freezing blue cheese can also be useful if you want to enjoy it in smaller portions over time. You can simply take out the amount you need and leave the rest frozen for later. This way, you can indulge in this strong and pungent cheese without having to worry about it going bad!
