How to Tell If a Can Is No Longer Safe
Most expired canned foods are still fine, but there are clear warning signs that a can should be discarded immediately:
- Bulging or swollen can – may indicate bacterial growth producing gas.
- Leaking or rusted can – any break in the seal compromises safety.
- Severe dents, especially at the seams – could damage the protective lining.
- Unusual odor, color, or liquid spurting upon opening – clear signs of spoilage.
If in doubt, don’t taste it. Trust your senses and throw it out.
