Shelf Life Tips

  • How long does an opened package of corn chips last? The precise answer depends to a large extent on storage conditions - store in cool, dry area.
  • How long do opened corn chips last at room temperature? Properly stored, an opened package of corn chips will generally stay at best quality for about 1 to 2 weeks at room temperature.
  • To maximize the shelf life of opened corn chips, keep package tightly closed.
  • Are opened corn chips safe to use after the "expiration" date on the package? Yes, provided they are properly stored and the package is undamaged - commercially packaged corn chips will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the corn chips will remain at peak quality.
  • Storage time shown is for best quality only - after that, the corn chips' texture, color or flavor may change, but in most cases, they will still be safe to consume if they have been stored properly, the package is undamaged, and there are no signs of spoilage (see below).
  • How can you tell if corn chips are bad or spoiled? The best way is to smell and look at the corn chips: if corn chips develop an off odor, flavor or appearance, or if mold appears, they should be discarded.
