Pantry
Not RecommendedUnsafe
Soft cheeses like mozzarella require constant refrigeration for safety and quality. Do not store at room temperature.
Refrigerator
Unopened package: 1 month; Opened package: 1 week
Store in original packaging or tightly wrapped in plastic wrap or an airtight container. Keep at 40°F (4°C) or below.
Freezer
6 months
For best quality, freeze in original unopened package or rewrap tightly in freezer wrap or heavy-duty foil. Freezing may alter the texture, making it crumbly, but it remains safe to eat.
Signs of Spoilage
- Mold growth (especially fuzzy or discolored spots)
- Sour, yeasty, or off-odor
- Slimy or sticky texture
- Significant discoloration
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Refrigerate mozzarella promptly after purchase and use. Discard any mozzarella left in the danger zone for too long.
Safe Handling
Keep mozzarella refrigerated at 40°F (4°C) or below.
Avoid cross-contamination by keeping cheese separate from raw meats and other potential contaminants.
Do not leave mozzarella at room temperature for more than 2 hours (1 hour if the ambient temperature is above 90°F/32°C).
Always wash hands, utensils, and surfaces after handling food.
