Fridge at 40°F (4°C) or below, freezer at 0°F (−18°C) or below. Freezer times are for best quality only: food kept frozen at 0°F (−18°C) or below stays safe indefinitely. A dash means the source gives no time.

Storage tips

  • Check the use-by date when you buy it, and put milk away as soon as you get home.
  • Shelf-stable (UHT) milk can live in the cupboard until you open it. After that it belongs in the fridge.
  • Don't leave it out of the fridge for more than 2 hours (1 hour above 90°F / 32°C). USDA advises throwing out perishable food left out longer than that.

Signs it's gone off

  • A sour smell, lumps or a curdled texture mean the milk has spoiled. Pour it out.
  • If it's past the times above, throw it out even if it smells fine.
