I've used out-dated canned goods as long as the cans aren't rusty, dented or bulging. Not long ago we decided to have tacos ------ UGH!!! They tasted awful! Looked at the pull-date on the taco shells ----- OMG they should have been dumped THREE years ago!!!!!! Generally, the pull dates on canned goods is just to tell you the food may be losing some of it's "excellant" quality.
