The study, published online February 13 in the journal Waste Management, comes at a time of heightened awareness of food waste and food safety among both consumers and policymakers. The U.S. Department of Agriculture estimates that 31 percent of food may be wasted at the retail and consumer levels. This study calls attention to the issue that much food may be discarded unnecessarily based on food safety concerns, though relatively few food items are likely to become unsafe before becoming unpalatable. Clear and consistent date label information is designed to help consumers understand when they should and should not worry.
Among survey participants, the research found that 84 percent discarded food near the package date "at least occasionally" and 37 percent reported that they "always" or "usually" discard food near the package date. Notably, participants between the ages of 18 to 34 were particularly likely to rely on label dates to discard food. More than half of participants incorrectly thought that date labeling was federally regulated or reported being unsure. In addition, the study found that those perceiving labels as reflecting safety and those who thought labels were federally regulated were more willing to discard food.
New - Industry - Standards - Date - Labeling
New voluntary industry standards for date labeling were recently adopted. Under this system, "Best if used by" labels denote dates after which quality may decline but the products may still be consumed, while "Use by" labels are restricted to the relatively few foods where safety is a concern and the food should be discarded after the date. Previously, all labels reflected quality and there was no safety label. Neff and colleagues found that among labels assessed, "Best if used by" was most frequently perceived as communicating quality, while "use by" was one of the top two perceived as communicating safety. But many had different interpretations.
