That swollen package could be a warning you cannot afford to ignore. Some puffed bags protect your food, while unexpected bulging in others may signal spoilage or a serious safety risk.

An inflated chip bag usually has a reassuring explanation: manufacturers commonly add nitrogen to cushion fragile chips and slow oxidation that makes oils turn rancid.

If a can is swollen, leaking, or badly damaged, do not open it or sample its contents. Neither smell nor appearance can reliably establish food safety. Keep suspicious packages closed and follow local food safety guidance for disposal. When shopping, inspect seals and containers; at home, follow refrigeration instructions rather than relying on dates alone. Photograph product and batch details if reporting a problem. Replacing questionable food is frustrating, but protecting your household matters more.
