How long does canned coconut milk last?

FoodKeeper gives canned coconut milk 2 to 5 years unopened, as a guide to quality. Once opened, that's 4 days in the refrigerator.

Throw away, without tasting, any can that's bulging, leaking, heavily rusted or deeply dented, or that spurts when opened.

How to store it

Keep it somewhere cool, and shake the can before opening. Leftovers go in a container: FoodKeeper gives them 4 days in the refrigerator or 3 months in the freezer.

USDA says temperatures below 85°F are best, and to avoid anywhere above or beside the stove, under the sink, or in a damp garage or basement. USDA says unused food may be refrigerated in the can, but a glass or plastic container keeps it tasting better.

What to look for

The thick cream rising to the top is normal. A sour smell, or a can that spurts on opening, isn't.

Throw a can away, without tasting, if it's bulging or swollen, leaking, heavily rusted or deeply dented, or if it hisses loudly or spurts when opened. USDA says a small dent on a can that's otherwise in good shape should be safe; a deep dent is one you can lay your finger into. Surface rust you can rub off isn't serious, but rust inside means don't eat the food. Double-bag anything suspect and put it in an outdoor trash can.

Worth knowing

Leftovers from a can can change texture in the freezer. They're better in cooking than on their own.

USDA FoodKeeper says: “Canned items will be safe to eat well past the 'use-by' or 'best by' date as long as the can shows no dents, rust, or swelling.”

How it works

FoodKeeper is USDA's food storage database. Its figures are guides to quality for food stored at cool room temperature, not safety cut-offs, and we show them as USDA gives them. FoodKeeper counts this from the date of purchase. Opened times start when you open the pack.

Where FoodKeeper gives no figure, we say so instead of guessing. The date printed on a package is the manufacturer's, and it's about quality except on infant formula.
