How to tell if blue cheese has gone bad?

There are many ways to check whether your cheese is able to eat or it has gone bad. So let me tell you how you can check by yourself.

Smell it

If your cheese has gone bad, then it will have a very strong unpleasant odor. This is the primary sign of your cheese gone bad.


If you see mold on the cheese, then it has gone bad, so throw it out. Also, if your blue cheese starts to change color, throw it out. When you cut a piece of blue cheese, and if its interior has changed from creamy white to yellow or brown, then it is no longer edible.

Weight your cheese

Another simple way to check whether your cheese has gone bad or not is by weighing it. If it has lost its original weight, then you should throw the cheese. It will be more than 3% of its original weight, so this is a very clear indication that your cheese has gone bad.

If you eat blue cheese before its expiry, it can cause foodborne illness, leading to nausea, vomiting, and diarrhea.

How to store blue cheese properly?

Store in Refrigerator

The easiest way to store cheese is through a refrigerator. You can keep it in your refrigerator at a 35 to 40 degrees Fahrenheit temperature. This is the perfect temperature for storing blue cheese, so you do not have to worry about its quality.

Keep in mind that once you open it, you need to store it properly. There are no extra precautionary steps for unopened cheese, but after opening it, you need to wrap it in plastic and cover it with aluminum foil.

  1. First of all, wrap your cheese in aluminum foil or freezer paper and then put it in a freezer bag.
