Canned food reserves: choose, inspect and handle opened packs

Canned food is useful only when it is shelf-stable and its packaging is sound. A metal container does not automatically mean the product is safe at room temperature.

1 Read storage instructions first

Check whether refrigeration is required before opening. Compare portions, ingredients and preparation requirements. Include a manual opener and test it with the cans you buy.

2 Separate suspicious packages

Do not use bulging, leaking or badly damaged cans. Never taste food to assess safety. Follow safe disposal instructions when in doubt, and do not feed questionable food to animals.

3 Plan to use the contents

Opening changes the storage requirements. Follow refrigeration and use instructions. Without a refrigerator, choose quantities that can be safely consumed promptly.

Practical checklist

  • Unopened storage instructions checked.
  • Sound cans with no leaks.
  • An opener tested.
  • Portions that avoid leftovers.

Frequently asked questions

Can I taste a suspicious can?
