MilkShelf Life, Storage, and Spoilage Guide
Pantry
Not RecommendedUnsafe
Pasteurized fluid milk must be refrigerated. Unopened UHT (ultra-high temperature) milk can be stored in the pantry until opened, then refrigerate.
Refrigerator
5-7 days after opening
Store milk in its original container on an inside shelf of the refrigerator, not in the door, where temperatures fluctuate. Keep the container tightly sealed.
Freezer
3 months
Milk can be frozen in its original container or an airtight freezer-safe container, leaving headspace for expansion. Thaw in the refrigerator. Quality may be affected (separation), but it remains safe.
Signs of Spoilage
- Sour or off odor
- Lumpy or curdled texture
- Discoloration (e.g., yellowish tint)
- Mold growth
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C). Milk should not be held in this temperature range for extended periods.
Promptly refrigerate milk after purchase and use. Discard any milk left out at room temperature beyond the recommended time limits.
Safe Handling
Always keep milk refrigerated at 40°F (4°C) or below.
Do not leave milk at room temperature for more than 2 hours (1 hour if temperature is above 90°F/32°C).
Avoid cross-contamination by keeping milk containers clean and separate from raw meats.
