The information that appears on food packaging is under more scrutiny than ever as many people carefully count their calories and regulators research companies’ health claims. However, there’s one line on nearly every item of food that bamboozles both consumers and producers alike: the “sell by” date. Or should we say the “use by” date? Whatever name it goes by on a particular package of food, misunderstanding of its meaning causes Americans to toss out more than 40 percent of their food prematurely.
According to a report from the Natural Resources Defense Council (NRDC) and Harvard University, millions of consumers mistakenly believe that sell-by dates indicate when an item will spoil. In fact, the dates refer solely to the food’s freshness, marking the time when it will be at its peak. Use of the dates came to prominence in the 1970s as consumers began to prepare fewer foods at home but still demanded information about production. Since the dates’ implementation was not an issue of public health, no national regulation arose that standardized their use. Instead the burden fell on states to define them, leading to a variety of clashing standards. “Sometimes a product needs a date, sometimes it doesn’t,” says study co-author Dana Gunders. “Sometimes a product cannot be sold after a different date. Or there is no requirement at all.”
Although the authors of this report do not want the dates to be eliminated, they do recommend a number of changes regarding their implementation. First of all, understanding the differences between “use by” and “sell by” could eliminate a good deal of confusion right off the bat. While “use by” is printed for the consumer to judge an item’s freshness, “sell by” dates are intended solely for manufacturers and retailers for inventory purposes. The researchers also recommend national legislation to clarify the dates’ meaning, which may already be in the works after the NRDC/Harvard report made a splash with a few legislators in Washington.
- How could clarifying the “freshness” debate be beneficial to consumers?
- Why have producers not improved the “use by, sell by” labels already?
