Today, in partnership with the Harvard Food Law and Policy Clinic, we are releasing a new report called The Dating Game: How Confusing Food Date Labels Lead to Food Waste in America. We took a deep dive into the intricacies of the date labeling laws in the U.S. in order to figure out what is behind those dates on food. And after all that, I can tell you this:
The U.S. food dating system is not a system at all. It’s a mess. And that mess is leading to a whole lot of perfectly good food going to waste.
While to most people it seems that there is a rationale, objective system behind the dates we see on our food, it’s really more like the Wild West. Take orange juice, for instance. In most states, there are no laws requiring that orange juice needs to have a date stamped on it. It is then up to up to the manufacturer to figure the whole thing out on their own, and there is a whole series of decisions they might go through, such as:
- Should the product have a date displayed at all? Their retail customers might demand this of them, otherwise it’s up to them.
- Which words to use? Will it be “use by” or “best before ”or even “sell by?” Up to them.
- What does the date convey? Is it that the taste might change a little, or perhaps the color, or do they just want you to see it as a fresh product even if it will last quite a while longer? There’s no definition, so in fact, a range of factors can feed into this decision.
- How is the date calculated? They might use lab tests, do consumer taste tests, look at literature values, or just sales data. Anything goes here.
You might think that there is similarity in the dates at least across orange juice brands, so that when you’re looking at two containers of orange juice, the dates are comparable, right? Nope. Not the case.
If you don’t believe me, try this experiment. Go into your favorite grocery store and peruse the milk section and its dates (or OJ, I just happened to do it with milk not all that long ago). At Trader Joe’s, I found milk with no words, different words, and different types of dates….all within the same Trader Joe’s brand. In fact, even the half-gallon and quart of the same fat free milk had different dates.
Seriously? How are these things supposed to mean anything? The problem is that when there’s that much variation, they don’t. And yet somehow, we all operate on the premise that those dates know better than we do whether our food is still good to eat.
So as consumers, the most important thing we can do is handle our food safely. Both business and government can be partners in this by providing education, but also by helping to make our food dating system more intelligible. We need a reliable, coherent, and uniform system of date labels that actually communicates what the dates are trying to convey.
You can learn more about the changes we recommend at www.fixfooddates.com, and even find a neat infographic demystifying those little levers on your fridge drawers. You can also help us collect examples of confusing dates by sending a photo of one that has perplexed you (along with a description of the product) to firstname.lastname@example.org, tweeting it to @NRDCFood, or posting it on our Facebook page. In return, we’ll make sure to send you to help you figure out whether that product may still have some life left.
From the United Kingdom, to the European Union and the United Nations, and even NRDC in last year’s food waste report – every entity that has investigated food waste has highlighted reducing confusion around expiration dates as one of the key “low hanging fruit” opportunities for reducing food waste. Let’s turn that opportunity into action.
