Certain foods, such as soft and fresh cheeses, should be chucked when you notice mold growth. This is because the mold that you see on the surfaces of these types of foods penetrates deeper into the food than other types.

However, if you see mold on hard cheese, like parmesan, there are things you can do to make the cheese edible. If you’ve ever asked, “Can you cut mold off mozzarella cheese?” the answer is yes. But only if the cheese is in its hard form.

To do so, simply cut one inch below and around the mold spot to ensure you’ve gotten all of the molds out. Also, be careful not to touch the mold with your knife. Doing so may contaminate it.

How to Tell if Mozzarella Is Bad

To know if your cheese is bad, consider the following:

  • Mold Spot on Cheese: Once a mold spot appears on your cheese, it’s time to take action. This doesn’t necessarily mean you have to pitch it, but you’ll want to cut the molded part out and keep an eye on the rest of the cheese to make sure it is still safe to eat. (Remember that if your mozzarella is soft, you’ll want to throw it out at the first sign of mold.)
  • Weird Smell: If you notice that your cheese has developed an off-smell, take notice. A sharp, sour, or putrid smell is bad news coming from mozzarella. Generally, mozzarella cheese has a very mild odor. Any strong offensive odors coming from cheeses may be alerting you that something is off. Note: If you notice mold on cheeses, try not to smell that area. Doing so may trigger asthma in some individuals and may aggravate any pre-existing respiratory conditions.
  • Change in Taste: Old mozzarella will suffer in terms of taste when it is expired. The flavor will grow bitter and sour over time. If you notice your cheese taking on a strange taste, it may be time to scrap it.
  • Change in Texture: Fresh mozzarella cheeses may take on a mushy texture when it grows old. Hard mozzarella may even get harder and become somewhat translucent. When this occurs, it may be a sign that your mozzarella is ready to kick the bucket. Opt for other fresh cheeses instead if you’re able.
  • Change in Color: Lastly, if you notice your cheese changing colors, you’ll want to take notice. Mold on cheese can take on a variety of hues. The includes blue mold on mozzarella cheese, green mold on mozzarella cheese, and white mold on mozzarella cheese. To be safe, we advise you avoid eating any rainbow-colored cheeses.
