How to prepare and store infant formula

It’s very important to know how to safely prepare and store commercial infant formula, to reduce the risk of illness from bacterial growth:

It’s also important to use the type of formula that’s appropriate for your baby’s age and health, and to sterilize all infant feeding equipment.

Storing prepared infant formula

  • If several bottles have been prepared, let them cool and place them in the refrigerator.
  • Use prepared bottles within 24 hours.
  • Cover open cans of powdered formula with a plastic lid. Store in a cool, dry place. Use within 1 month.
  • Tightly cover open cans of ready-to-feed or liquid concentrate formula and put them in the refrigerator. Use within 48 hours after opening.
  • Do not freeze any kind of infant formula. Freezing it changes the fat.

Preparing infant formula away from home

  • Prepare infant formula, cool and place in refrigerator.
  • Transport prepared formula in a cooler bag with ice packs.
  • Use formula within 2 hours or place in refrigerator.
  • If you’re unsure about the safety of the water where you will be visiting, use bottled water and follow the regular sterilization process.
