Pantry
Not RecommendedNot recommended (once opened)
Unopened packages may be stored at room temperature until the 'best by' date, but refrigeration is always recommended for quality. Once opened, do not store in pantry.
Refrigerator
3-4 weeks (opened)
Store in original packaging or a tightly sealed container or bag to prevent drying out and absorption of odors. Keep at 40°F (4°C) or below.
Freezer
6 months
Freeze in original unopened package or rewrap in airtight freezer bags or heavy-duty aluminum foil. Thaw in the refrigerator. The texture may become crumbly after freezing, but it remains safe to eat.
Signs of Spoilage
- Visible mold growth (especially fuzzy or discolored spots)
- Off-odor (sour, ammonia-like, or yeasty smell)
- Slimy or sticky texture
- Significant discoloration beyond normal variations
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Promptly refrigerate or discard shredded cheese that has been left in the danger zone for too long.
Safe Handling
Keep shredded cheddar cheese refrigerated at 40°F (4°C) or below.
Do not leave shredded cheese at room temperature for more than 2 hours (1 hour if the ambient temperature is above 90°F/32°C).
Always use clean utensils and surfaces when handling cheese to prevent cross-contamination.
