To ensure you’re enjoying your parmesan at its peak, it’s crucial to know the telltale signs of spoilage.

Physical Appearance
- Mold: The presence of mold on the surface of the parmesan is an unmistakable indicator of spoilage. Avoid consuming any cheese with visible mold.
- Discoloration: Fresh parmesan has a light yellow hue. If you notice any darkening or discoloration, especially greenish or reddish patches, discard the cheese.
- Texture: Good parmesan has a hard, crumbly texture. If it becomes soft, slimy, or crumbles excessively, it’s time to let it go.
Smell and Taste
- Sour aroma: Parmesan should have a nutty, slightly fruity aroma. If you detect a sour or pungent odor, it’s a sign of spoilage.
- Bitter taste: Fresh parmesan has a pleasant, slightly salty flavor. If it becomes bitter or rancid, discard it immediately.
Other Signs
- Expiration date: Always check the expiration date on the packaging. Consuming expired cheese can be hazardous to your health.
- Storage conditions: Parmesan should be stored in the refrigerator at temperatures between 32-40°F (0-4°C). If it has been left out at room temperature for an extended period, it may have spoiled.
- Homemade parmesan: If you’ve made parmesan at home, it’s crucial to follow the recipe carefully and ensure proper storage to prevent contamination and spoilage.
