It is not very safe as the food in this can could have developed a foodborn illness. One very well known foodborn illness associated with canned foods is botulism. One way you can tell is if there are dents, bumps, or scratches in the can. If so throw out the food.

Canned food can be eaten after the expiration date as long as the can does not show any signs of bulging. In addition, if the can releases a hissing sound after being opened. It should not be eaten because air in canned foods probably has bacteria growth.
