Signs cereal has gone bad
- A loss of crunch and a stale, cardboard texture.
- A musty or off smell.
- Clumping or any sign of pantry pests.
When in doubt, throw it out — the cost of a spoiled meal isn't worth the risk.
Best way to store cereal
Sealed boxes keep for months, but once the inner bag is open the cereal goes stale and loses its crunch fast — roll the bag down tight or move it to an airtight container.
