Expired potato chips: what you need to know to protect your health

Potato chips, the crunchy and savory snack beloved by many, are a pantry staple found in countless homes. But how long do they last before they become stale or unsafe to consume? The answer to the question “are potato chips expired” depends on several factors.

How to Check Potato Chip Expiration

1. Check the Best-By Date:

Most potato chip packages have a best-by date printed on them. This date indicates the manufacturer’s estimate of how long the chips will retain their optimal flavor and quality.

2. Examine the Packaging:

Look for any signs of damage to the packaging, such as tears or holes. Compromised packaging can allow moisture or pests to enter, affecting the freshness of the chips.

3. Inspect the Chips:

Remove a few chips from the bag and examine them closely. If the chips appear stale, crumbly, or discolored, they may be expired.

Factors Affecting Potato Chip Shelf Life

1. Storage Conditions:

Potato chips should be stored in a cool, dry place away from direct sunlight. Exposure to heat and moisture can accelerate spoilage.

Chips made with preservatives or antioxidants may have a longer shelf life than those without.
