Unopened shredded cheese typically has a longer shelf life compared to opened cheese due to its packaging that helps protect it from external contaminants. The shelf life of unopened shredded cheese can vary depending on the type of cheese and how it is stored. Here are some general guidelines:
Factors Affecting the Shelf Life of Unopened Shredded Cheese
Several factors can influence the shelf life of unopened shredded cheese, including:
- Type of Cheese: Hard cheeses like cheddar or Parmesan tend to have a longer shelf life compared to softer cheeses like mozzarella or feta.
- Packaging: Cheese that is vacuum-sealed or has airtight packaging will last longer than cheese stored in resealable bags.
- Storage Conditions: Proper storage is crucial to extending the shelf life of shredded cheese. Cheese should be stored in a cool, dry place away from direct sunlight and heat sources.
Shelf Life of Unopened Shredded Cheese Varieties
Each type of cheese has its own shelf life when unopened. Here is a general guideline for some common types of shredded cheese:
Cheddar Cheese:
- Unopened shredded cheddar cheese can last for 1-2 months past the expiration date when stored properly in the refrigerator.

Tips for Properly Storing Unopened Shredded Cheese
To prolong the shelf life of unopened shredded cheese and maintain its quality, follow these storage tips:
- Store in the Refrigerator: Always store unopened shredded cheese in the refrigerator at a temperature of 40Β°F (4Β°C) or below.
- Keep it Sealed: If the original packaging is resealable, ensure it is tightly sealed after each use to prevent air exposure.
- Use airtight Containers: If the original packaging is not resealable, transfer the shredded cheese to an airtight container or resealable bag.
- Avoid Moisture: Keep the shredded cheese away from moisture to prevent mold growth. Place a paper towel in the bag/container to absorb excess moisture.

Even when stored properly, shredded cheese can eventually spoil. Here are some signs that indicate shredded cheese has gone bad:
