3 Ways to Tell if a Blue Cheese is Broken

Blue cheese contains an edible mold, which is responsible for the very characteristic flavor and smell of the spice. As much as this is not to everyone's liking, it can be consumed without any problems. Even so, your piece can spoil, just like any other cheese, and it is important to know how to assess the freshness of the food before consuming it.


Method 1 of 3: Analyzing the Cheese

Tell When Blue Cheese Is Bad Step 1

Step 1. Smell it

The best way to find out if the cheese has gone bad is to sniff it. A fresh piece has a very strong and characteristic odor that changes when it starts to spoil. If it smells like ammonia, it's best to throw it away.

It's always good to sniff the cheese as soon as you get home to identify its natural odor and let you know when it starts to change

Step 2. Look at the color

A fresh blue cheese is already moldy, with slightly blue or greenish spots. It is important, therefore, to note the hue of the creamy part of the cheese, which is usually white, beige or yellowish. If it starts to turn pink, brown, green, or blue, throw the cheese away.

  • As with the question of smell, look at the color of the cheese once you get home, so you can see when it changes.
  • In addition to color changes, look at the surface of the cheese. If you notice any change in texture, such as if the piece is sticky or fuzzy, throw it away.

If the odor and appearance remain the same, just do the last test: taste a piece. As much as blue cheese has a strong and characteristic flavor, it usually turns bitter when spoiled. If the piece doesn't taste good, throw it away.

Normally, eating a small piece of spoiled cheese shouldn't be enough to make you sick

When kept in the fridge, blue cheese can last a long time. Check the expiration date on the package and know that the product can normally be consumed for one to two weeks after the deadline stipulated by the manufacturer. In most cases, therefore, it can be stored for three to four weeks.

To keep the cheese as fresh as possible, set the refrigerator at a temperature below 4 °C

Step 3. Discard frozen cheese after six months

When stored in the freezer at -17 °C, the cheese can last indefinitely. In other words, freeze what you are not going to consume within a month so you don't lose anything. Still, to maintain the flavor and texture, do not store the cheese for longer than six months.

Step 2. Pack the cheese twice

It doesn't matter if you keep it in the fridge or freezer, it's important to pack it well to keep it fresh longer. Start by wrapping the piece in parchment paper. Then wrap the paper with PVC film or aluminum foil.

  • If you are going to freeze the cheese, put it already packed in a plastic bag.
  • If you're afraid of flavor contamination, it's a good idea to keep the cheese packaged inside a lidded jar for extra protection.

Step 3. Store on the last shelf of the refrigerator

The colder it is, the longer the cheese will last. Since the bottom of the refrigerator is usually cooler, it's a good idea to store the piece there to preserve it longer. If the refrigerator has drawers at the bottom, use them; as they are not opened very often, the temperature remains more stable and preserves food more.


  • If the cheese shows signs of being rotten when opened, return it to the store. Take the invoice and ask for a refund or a new product.
  • As it is quite moist, blue cheese tends to spoil faster than dry varieties.


  • Even if only one part looks spoiled, it's best to discard the entire piece, as bacteria or mold may be present throughout the cheese.
  • If you get sick after consuming a cheese and you suspect it is spoiled, it's a good idea to see a doctor.
