A couple of points to note:
Quote:
According to a report from the NRDC and Harvard University, manufacturers typically use methods such as lab tests and taste-testing to set these label dates. But consumers have no way of knowing the background. In many cases, dates are conservative, so if you eat food past that date, you may not notice any difference in quality, especially if the date has recently passed.

"As a general rule of thumb, most canned foods (for example, canned tuna, soups, and vegetables) can be stored for two to five years, and high-acid foods (canned juices, tomatoes, pickles) can be stored for a year up to 18 months, according to the USDA. Watch out for dents and bulges in cans, though. That might be a sign it’s time to toss those products.
If you’re still not sure whether a product or item is worth saving past its date label, a free app the USDA created, FoodKeeper, will help you determine how soon specific items—everything from oats to coconut milk to maple syrup—should be consumed if it’s stored in the pantry, or how long it will last in your refrigerator once it’s opened."
