How to tell if cheese is bad

Answer

To tell if cheese is bad, check for a change in color, texture, or odor. If the cheese has turned brown, gray, or green, has a slimy texture, or has a strong, foul odor, it is spoiled and should be discarded.

Change in color

Fresh cheese is typically white, yellow, or orange. If the cheese has turned brown, gray, or green, it is spoiled. This is because bacteria have started to grow on the cheese and produce pigments that change the color.

Change in texture

Fresh cheese is firm and crumbly. If the cheese is soft, mushy, or slimy, it is spoiled. This is because bacteria have started to break down the proteins in the cheese, making it softer and more watery.

Change in odor

Fresh cheese has a mild, cheesy odor. If the cheese has a strong, foul odor, it is spoiled. This is because bacteria have started to produce waste products, which have a strong, unpleasant odor.

Presence of mold

Mold is a fungus that can grow on cheese. If you see mold on the cheese, it is spoiled and should be discarded. Mold can produce toxins that can make you sick.

If you are unsure whether or not cheese is safe to eat, it is always best to err on the side of caution and discard it.

  • If you have a lot of cheese that you are not sure how to store, you can freeze it. Cheese can be frozen for up to three months. When you are ready to use the cheese, thaw it in the refrigerator overnight.
