Coconut milk is a creamy liquid extracted from the grated flesh of mature coconuts, and unlike regular dairy, coconut milk has a much longer shelf life.

However, coconut milk can go bad, and its shelf life depends on good canning, storage conditions, and whether the can has been opened.

Low-acidity canned foods, like coconut milk, will last two to five years on the shelf and three to four days after opening when kept in the refrigerator.

Regardless of the expiration date on the can, always check for freshness. Spot any changes in color, texture, and odor — spoiled coconut milk will not be milky white.

A bad can could also have an off-putting smell or mold. While shopping for canned coconut milk, avoid dented, rusted, and bulging cans, which may have compromised seals.

Improper canning can also lead to bulging. This indicates air is trapped inside the can, which can lead to bacterial growth, and it's best to discard it.
