Full Answer

When margarine goes bad, it has a rancid taste that indicates the product should be discarded. Spoiled margarine is unsafe for consumption because its polyunsaturated fats can form harmful free radicals in the body. Many common foods are safe to use beyond the date on the label if they are stored in an appropriately cold refrigerator.
