Storage tips
- Keep powdered milk sealed in a cool, dry cupboard after opening to hit the window above. It does not need refrigerating.
- Dried and powdered dairy keeps in a sealed container in the cupboard. Once you mix it with water it becomes a fresh dairy food, so refrigerate what you make up and use it within a few days.
How can you tell if powdered milk has gone bad?
- A sour or off smell, or milk that has thickened, curdled or separated.

Shelf-life windows come from the USDA FoodKeeper, published by the USDA Food Safety and Inspection Service (public domain); we vendor the FSIS FoodKeeper dataset and refresh it in place. These are quality estimates, not food-safety determinations or guarantees: actual condition depends on storage and handling, and harmful bacteria may not have obvious signs.
