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.
