Grated parmesan cheese is bad if not refrigerated!

Grated parmesan cheese is a common ingredient in many recipes, but it can quickly go bad if it is not refrigerated. The high-fat content of the cheese makes it prone to rancidity, and the grated texture means that bacteria can easily take hold. 

If grated parmesan cheese is not refrigerated, it should be used within two days. After that, it will start to develop an off-flavor and a slimy texture.

So if you’re planning on using grated parmesan cheese in your cooking, be sure to keep it properly refrigerated. Otherwise, you might end up with a dish that is anything but cheesy.

6 Signs that Parmesan Cheese Has Gone Bad 

Just like any other food, Parmesan cheese can also go bad. However, because Parmesan is a hard cheese, it can be difficult to tell when it has gone bad. Here are six signs to look for:

1. The cheese has developed mold

Mold is a common occurrence on cheeses, and while some types of mold are safe to eat, others can cause serious illness. If you see mold on your Parmesan, it is best to throw it away.

2. The cheese has changed color

Parmesan should be a pale yellow color. If it has started to turn green or brown, this is a sign that it has gone bad.

3. The cheese has a sour smell

While all cheeses have a distinct smell, they should not smell sour. If your Parmesan smells sour, it is no longer safe to eat.

4. The cheese is crumbly or hard

Parmesan should be firm but not hard. If it is crumbly or difficult to cut, this is a sign that it has gone bad.

5. The cheese tastes different from usual 

If your Parmesan tastes sour, bitter, or otherwise off, it has gone bad and should not be eaten.

6. The expiration date on the package has passed

This is the most obvious sign that your Parmesan has gone bad and should not be eaten. Be sure to check the expiration date before consuming any cheese.

Whether you’re using Parmesan cheese in your cooking or simply enjoying it as a snack.  With proper storage, it can last for several months in your fridge.
