How do you know if a canned vegetable is still safe to use?

- Bulging or swollen cans: This is the most obvious sign of spoilage. It indicates that the contents of the can have produced gases, which can be a result of bacterial growth. Avoid consuming the contents of any bulging cans.

- Dented or heavily rusted cans: Dents and rust can compromise the integrity of the can, creating a potential entry point for bacteria. While small dents may be harmless, it's best to discard cans that are severely dented or heavily rusted.

- Leaking cans: Any liquid seeping out of the can is a red flag. Leaking cans indicate a breach in the seal, allowing bacteria to enter. Avoid consuming the contents of leaking cans.

- Off-odor or discoloration: If you notice an unusual or foul odor or if the vegetables appear discolored, it's best to discard the can. Spoiled vegetables may have an off smell or an unnatural appearance.

- Unusual taste: If the vegetables taste abnormal or sour, it's likely that they've spoiled and should be discarded.

If there are visible signs of spoilage or any doubt about the safety of a canned vegetable, it's always better to discard the can rather than risk consuming spoiled food. When in doubt, throw it out.
