A supermarket in Boston is going to sell only food that's past its sell-by date. So what are they, asks Rajini Vaidyanathan.
In the US alone, 40% of food is thrown out, partly because of
confusing date labels, telling consumers to "use by", "sell by" and
"enjoy by" a certain time. Some of the dates are not about safety but taste, says Dana Gunders, a food scientist from the Natural Resources Defence Council (NRDC), which has issued a report saying much of the food labelled bad is actually perfectly edible.
