No, not that kind of date! It can’t be healthy to eat food past the “expire” date, can it? What about the “sell by” or “use by” dates? These labels are confusing, and really don’t mean very much. We might as well use an Aztec Calendar Wheel for the same amount of clarity!
They give us the the date by which the manufacturer has deemed the food to be closest to the taste that the manufacturer decided was best. “But companies want people to taste their products as best they can at the optimum, because that’s how they maintain their business and their market shares.” (Institute of Food Technologists) “There should be a standard date and wording that is used. This is about quality, not safety. You can make your own decision about whether a food still has an edible quality that’s acceptable to you.” (Harvard Food Law & Policy Clinic) All sources say the same thing. Smell it. Taste it. You can tell if a food has gone bad.
This is much different than contamination. “Bacteria, viruses, or parasites mainly cause foodborne illness. Many foodborne illnesses are a result of bacteria or viruses, which are microorganisms or “germs” that occur either naturally in foods or are spread as a result of poor practices, such as cross contaminating foods or improper handling during food preparation. Bacteria can rapidly multiply under the right conditions.” (MDH)
Bottom line: Let your senses (including common sense) guide you, and take basic precautions including hand-washing and sanitary kitchen practices. (Information on food safety here.)
