"food expiration dates" news and stories

We've all been there: You open the fridge, reach for the milk, and notice the date on the carton says it expired yesterday. You gingerly sniff the carton, fully expecting to be overwhelmed by noxious fumes but instead all you can smell is . . . milk.

According to University of Minnesota food scientist Ted Labuza (who spoke to Slate), perishables like milk and meat have a three- to seven-day grace period after the expiration date, assuming you are a normal person and store said perishables in the fridge and not, say, the sauna. The fact is, the "sell by" date that appears on that questionable gallon of milk serves as a guideline for stores on when they should pull products from their shelves -- not when you should indulge in a last sip. Rather than being an indicator of the product's safety span, the date implies when a food's quality -- its taste, aroma and appearance -- would be at peak conditions.
