What is recommended for storing canned products safely?

The recommendation to avoid dented, bulging, or leaking cans is based on safety and food quality concerns. Canned products that exhibit these signs may be compromised and could pose a risk of foodborne illness. Dented cans can sometimes have tiny holes or breaks that allow harmful bacteria to enter. Bulging cans might indicate that gas is being produced inside due to spoilage, and leaking cans clearly show that the contents are either at risk of contamination or have already spoiled. Ensuring that canned goods are in good condition before consumption is essential for maintaining food safety and preventing health hazards.

The other options do not prioritize food safety to the same degree and could lead to unintended consequences if followed. For instance, stacking cans outward or storing them in direct sunlight may expose them to heat and decrease their shelf life, while rotating them frequently regardless of condition doesn’t address the importance of checking for signs of damage or spoilage.
