How long does a can of baby formula last?

The shelf life of a can of formula varies depending on the brand, nutrient level and whether or not the can is open. The U.S. Food and Drug Administration requires all infant formula manufacturers to include a “use-by” date stamp on every can.

Both liquid and powdered infant formula should be used by the date listed on the label. Once liquid formula has been opened or powdered formula has been mixed, they should be used or thrown away in 24 hours. Once opened or mixed, formula should also be stored in a refrigerator. Infant formula is one food product that should always be thrown away once it has expired regardless of how much or little remains in the can.
