Walk into a grocery store, and you'll face a cacophony of expirations dates: "sell by," "use by," "freeze by." Sometimes you'll even see "enjoy by" or "delicious if used by."
The confusion over food expiration dates is more than just an inconvenience for shoppers. All that bad labeling means a lot of good food goes to waste, as consumers misinterpret dates and throw away refrigerators full of edible food.
