About baby food. Baby food spoils quickly once opened because it lacks the preservatives found in many packaged foods, and jars or pouches should be treated as fresh food, not shelf stable. Unopened jars and pouches keep well until their date, but opened baby food needs prompt refrigeration and quick use. All baby food.

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.
