 Do you pay attention to information printed on food labels? From eye-catching designs companies use to entice you to buy a product to nutrition facts panels to the tiny dates printed on packages. There's a lot going on to be sure. For policymakers, they hope that refining date labels on food packaging will help reduce the amount of uneaten food ending up in landfills. Food Waste is a major contributor to greenhouse gas emissions. The Food and Drug Administration and the Food Safety and Inspection Service recently asked for public input on food date labels. So, we decided to gather some experts together to talk about this important policy tool. Roni Neff is a professor in the Johns Hopkins Bloomberg School of Public Health and Senior Advisor at the School's Center for a Livable Future. Her research looks at the intersection of food waste policy, climate change, and food system resilience. Brian Roe is a professor at the Ohio State University Department of Agricultural, Environmental and Developmental Economics. His work focuses on issues including agricultural marketing, information policy, behavioral economics, and product quality. Ruiqing Miao is an associate professor of agricultural economics and rural sociology at Auburn University's College of Agriculture. His research emphasizes sustainability, innovation, and decision making. Interview Summary Brian, let's begin with you and let's make sure everyone's on the same page. Can you talk to us a little bit about what date labels are and where they are on packaging. And what is industry required to include in terms of these date labels? Yes, so date labels, we see them anytime we pick up a food package. Most packages are going to have some type of date label on them. Oddly, federal law doesn't regulate these or really require these other than the exception of infant formula, which is the only federal requirement domain out there. But in the absence of federal regulation, states have kind of done their own thing. About 40 different states require date labels on at least some food products. And about 20 states prohibit or restrict the sale or donation of food past the label date. And even though states that require date labels, manufacturers can still choose the dates. There are no real regulations on them. So, recognizing that confusion over date labels can lead to unnecessary food waste, Government and industry actors have made, you know, some efforts to try to standardize date labeling language. But nothing terribly authoritative. Now, some states have introduced bills that seek to standardize date labels, with the motivation to try to get rid of and reduce food waste. California being perhaps the most recent of these. In 2024, they passed a bill that prohibits the use of any date label other than 'Best if Used By,' the phrase that goes along with foods where the date represents kind of a quality indicator. And then the phrase 'Use By,", if that date has some implications for product safety. The bill doesn't go into effect until July of '26, so we're going to see if this is going to create a domino effect across other states, across the food manufacturing center or even bubble up and be dealt with at the federal legislation level. Now, industries tried to do things before. Back in 2017, the Food Marketing Institute and the Grocers Manufacturers Association had a standardized date labeling suggestion that some firms bought into. FDA has given out some guidance about preferring 'Best if Used By' on certain food products to indicate quality. But again, we're all kind of waiting to see if there might be a federal legislation that kind of brings these state labels into check. Thanks, Brian. And it's really important to know about the policy landscape and the fact that there hasn't been a federal policy across all foods. And it's interesting to see the efforts of, say, in California. I think this begs the question; how do consumers actually process the information of date labels? This fascinated us too. A very clever person at Ohio State that I work with, Dr. Aishwarya Badiger, led a study I was part of. We enlisted consumers to come into the Consumer Evaluation Lab that we have here on campus and evaluate samples of milk. They were presented with the label of each milk. We gave them a little glass with a nose full of the milk that they could sniff. So, they're looking at the date label, they're given the sample they could smell, and then we kind of asked them, Hey, if this were in your fridge, would you keep it or toss it? But the entire time we actually had them fitted with special glasses that precisely track their eye movements so we could understand kind of which information they were looking at while they went through the whole process of evaluating and then making their decision. Consumers overwhelmingly looked at the date itself on the package and largely ignored the phrase or the words that go along with the date. In fact, for more than half of the...
