How long can grated cheese last in a refrigerator?

Here's a breakdown:

* Freshly grated cheese: This is the ideal situation, as it's the freshest. It will last about 7 days in the refrigerator.

* Pre-grated cheese: This can last slightly longer than freshly grated cheese because it has been treated to prevent clumping. It typically lasts for about 10 days.

* Hard cheese: Hard cheeses like cheddar and Parmesan tend to last longer than soft cheeses. They can stay fresh for up to 2 weeks.

Here are some tips for storing grated cheese:

* Use airtight containers: This will prevent the cheese from drying out and absorbing odors from other foods.

* Store in the coldest part of the refrigerator: This will help slow down the growth of bacteria.

* Avoid freezing grated cheese: Freezing can change the texture of the cheese.

To determine if your cheese has gone bad, look for the following signs:

* Mold: This is a clear sign that the cheese has spoiled.

* Slimy texture: This is also a sign of spoilage.

* Off odor: If the cheese smells sour or rancid, it's best to throw it away.

If you're unsure whether your cheese is still good, it's always best to err on the side of caution and throw it away.
