We all know that commercially canned foods are marked with expiration dates, but how long can a can of food REALLY keep before going bad?

Answer If kept cool, for as long as the can's not bulging or smelling bad

In 1974, a test was run on a load of canned goods that sunk in the Missouri River in 1865. The tomatoes, vegetables, peaches, and oysters still had significant nutritional value and showed no microbial growth; in other words, they were safe and tasty. The actual shelf life depends on how the cans have been handled and whether they are kept cool. Ultimately, you're better safe than sorry, so never eat food from a bulging, dented, or rusted can.
