MilkShelf Life, Storage, and Spoilage Guide
Pantry
Not RecommendedNot recommended for regular pasteurized milk
Regular pasteurized milk must be refrigerated immediately. Unopened, shelf-stable (UHT) milk can be stored in a cool, dark pantry until opened, then refrigerate.
Refrigerator
7 days after opening, or by 'use-by' date if unopened
Store milk in the coldest part of the refrigerator, typically on a shelf rather than in the door, which is often warmer. Keep the container tightly sealed.
Freezer
3 months
Milk can be frozen in its original container or an airtight freezer-safe container, leaving about 1 inch of headspace for expansion. Thaw frozen milk in the refrigerator. Quality (texture and separation) may be affected, but it remains safe.
Signs of Spoilage
- Sour or off odor
- Lumpy, curdled, or thickened texture
- Discoloration (e.g., yellowish tint)
- Mold growth on the surface or container
- Bloated or bulging container
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
Refrigerate milk promptly after purchase and use. Discard any milk that has been left in the danger zone for longer than the recommended time limits.
Safe Handling
Keep milk refrigerated at 40°F (4°C) or below at all times.
Do not leave milk at room temperature for more than 2 hours (1 hour if the temperature is above 90°F/32°C).
Always check the 'use-by' or 'sell-by' date on the packaging.
Avoid cross-contamination by ensuring milk containers are clean and not placed near raw meats or poultry.
