Does powdered infant formula spoil?

Maiyko AI ADVISOR

The real reply from the in-app AI advisor

Unopened powdered formula doesn't spoil until the expiration date. Once opened, shelf life changes:

  • Opened container: Keep in a cool, dry place with a tightly sealed lid for up to 1 month. After a month, discard—vitamin value drops and moisture can degrade it.
  • Mixed (reconstituted) formula: At room temperature, no more than 1 hour; in the fridge (at 4°C), no more than 24 hours. Never reuse formula touched by the baby's mouth.
  • Storage tips: Don't keep formula near the stove, in direct sunlight, or in the refrigerator door. Seal the container tightly after each use.

Signs of spoilage: Lumping, color change, foul odor, insect infestation—discard.

Summary: Unopened → expires as labeled. Opened → use within 1 month. Mixed → immediate or refrigerated within 24 hours.
