How to store formula
Best place: the fridge. USDA gives formula a fridge time (1 day, after opening) and no pantry time, so it belongs in the fridge as soon as you get home.
No guideline
Should be discarded after use-by date.

How to tell formula has gone bad
General signs for baby food, the group USDA lists formula under.
- Lid pops or bulges when you open the jar
- Sour or off smell instead of the usual mild scent
- Colour looks darker or duller than a fresh jar
- Watery separation that will not stir back together
- Mould spots on the surface or under the lid
More on baby food. The times above are quality guidelines, not safety limits; food that shows these signs goes out regardless of the date.
Storage habits that make the difference
Store unopened jars and pouches in a cool, dark cupboard away from the stove. Once opened, refrigerate immediately in a sealed container and use within the time on the label, usually one to three days. Never feed a baby straight from the jar with a used spoon, since saliva speeds spoilage; scoop out a portion instead.
