"Simplifying "sell by" dates should help reduce food waste, which releases greenhouse gases as it rots in landfills. The move could save people money, too."
"'Best by.' 'Enjoy before.' 'Sell before.' 'Display until.' These labels on packages attempt to convey to consumers whether they should buy a frozen chicken, toss a questionable jug of milk or bother opening a dusty can of beans.
Instead, they confuse people—and send a lot of perfectly edible food into the trash.
Every year, American consumers alone throw away $29 billion worth of good food. Much of it rots in landfills, venting methane, a potent climate-warming gas."
