A Can Is on Sale. Take a Second Look at the Packaging.
Grocery
Before buying canned food, check for signs of damage. USDA FSIS advises against using cans that are leaking, bulging or badly dented. A low price cannot make a damaged container safe.
Choose a sound can instead. If you find a suspicious container in the pantry, discard it without tasting its contents. A product that spurts when opened is also a warning sign.
Store commercial cans in a cool, dry place and rotate older usable stock forward. Checking packages while putting groceries away makes it easier to spot damage early.
