When You Should Definitely Throw a Can Away
While most expired canned food is harmless, there are situations where disposal is absolutely necessary. Never consume food from a can that shows:
- Bulging or swelling: This can indicate gas production from bacteria.
- Leaking liquid or severe rust: These compromise the airtight seal.
- Deep dents, especially along seams or edges: Dents can break the internal lining.
- Foul smell, mold, or strange appearance after opening
- Sudden spurting liquid when opened
If something seems off, trust your instincts. Never taste questionable canned food—discard it immediately.
