How to tell if baby cereal is bad

Jar lids that do not pop on opening, or damaged pouches — discard.
Baby cereal past the expiration date
Unopened
Follow the package date. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 1 month in the pantry from the day you open it.
How to keep baby cereal fresh longer
- Should be discarded after use-by date.
- Follow the label and your pediatrician's instructions first.
- Refrigerate prepared or opened products right away.
