Does Canned Coconut Milk Ever Go Bad?

Coconut milk does go bad eventually

According to the USDA, low-acidity canned foods, such as coconut milk, can remain shelf-stable for two to five years and last three to four days after being opened and stored in the refrigerator. In this case, it's advisable to keep any unused coconut milk in an airtight container in the fridge. For unopened cans, store them in a cool, dry area of your pantry.

Before pouring a can of coconut milk into your cooking, take a moment to examine it. Regardless of the expiration date on the can, always verify its freshness. Look for any changes in color, texture, or smell. Spoiled coconut milk will not have a milky white appearance; instead, it will appear darker. Be cautious of a lumpy texture that remains even after shaking the can. You may also notice an unpleasant odor or mold. If you observe any of these signs, it's best to discard the coconut milk.

While expiration dates on cans can serve as a helpful reference for freshness, they are not always strictly regulated. Trust your senses—your eyes and nose will be your best allies in identifying spoiled coconut milk.

Look for dents, bulging, and rust

While you're at the store, take a moment to inspect cans for any dents, rust, or bulging. If you find any of these issues, the can may be compromised. The USDA cautions that cans can become dented during shipping, which may lead to a faulty seal. This can allow air and bacteria to enter, resulting in food spoilage. Additionally, improper canning practices can cause bulging, indicating trapped air that can promote bacterial growth, so it's advisable to discard such cans.

Metal cans are also susceptible to rust, which signifies corrosion of the tin container and can contaminate the food inside. Furthermore, damage to the can's lining may expose the food to the metal, potentially leading to chemical contamination, especially with certain metals that can react with acidic or alkaline foods. However, coconut milk is less acidic, making it less likely to cause corrosion. Always check for these potential damages whenever you pick up a can, whether in the store or at home.
