How Do I Know If The Cheese Has Gone Bad?

If you have a block of cheese in your refrigerator, it’s easy to tell if it’s gone bad. The first thing you need to do is look at the wrapper on the cheese. If there is mold on the wrapper, then the cheese itself has probably gone bad. The next thing you need to look at is how hard the cheese is. If it’s hard as a rock, then it’s definitely time to throw out that block of cheddar and get yourself some new cheese.

The Cheese Is Slimy Or Moldy:

When you cut open a piece of cheese and it’s slimy, it’s definitely gone bad. This is because the cheese has been exposed to too much moisture and bacteria, which has caused it to spoil. If you see mold on your cheese, throw it away immediately.

The Cheese Has A Sour Smell:

If your cheese smells sour, it’s probably no longer safe to eat. This is because bacteria from the air can get inside the packaging (or on your fingers) and contaminate the surface of the cheese itself. Bacteria love to feed on sugars found in dairy products like cheese, so if you notice this smell, don’t risk eating it!

Although some cheeses have distinctive smells that are considered normal when they are fresh, if anything seems off, throw it out!
  • If you notice any mold growing on your mozzarella cheese, throw it away immediately because this mold can cause serious health problems if consumed by humans or pets alike!

It has a sweet flavor that goes well with tomatoes and other fresh vegetables, or as an ingredient for pizza and pasta dishes.

Mozzarella cheese can be stored at room temperature for up to one day before refrigeration is necessary. If it is going to be stored at room temperature longer than that, wrap it tightly in plastic wrap or place it in an airtight container so that no air can reach the surface of the cheese.


Mozzarella cheese can be stored in its packaging for up to two days at room temperature before opening. After opening, wrap the cheese tightly in plastic wrap or place it in a resealable plastic bag and keep it covered with water or whey — the liquid left over after making other cheeses — to prevent mold growth.
