The Meaning of a Food Label Expiration Date. Is there one?
Having worked for Oscar Mayer buying food labels and packaging, this article caught my eye. Oscar Mayer is an old company and was left pretty much alone by its owners until Kraft got involved. A big time of the year was July 4th for hot dogs. The author is going to tell you the food labels on products are not looked at and reviewed. If he means “good until such” date. I am sure there is data backing it up. Somebody i Quality reviewed the data backing up the date.
I can safely and for sure tell you that food labeling is approved by the USDA and or the FDA. A small change in a label or packaging such as Lunchables requires approvals. If it is a mandated change, you may be scrapping $thousands in packaging. It is not taken as lightly as the author would have you believe.
My claim to fame at Oscar Mayer was the Lunchables sleeve. We went from virgin SBS board to recycled packaging board with little change in whiteness. A $million cost save. Processed foods have low margins so this was a big deal.
It is not a bad article . .
“Expiration Dates Are Meaningless,” The Atlantic, Yasmin Tayag
For refrigerators across America, the passing of Thanksgiving promises a major purge. The good stuff is the first to go: the mashed potatoes, the buttery remains of stuffing, breakfast-worthy cold pie. But what’s that in the distance, huddled gloomily behind the leftovers? There lie the marginalized relics of pre-Thanksgiving grocery runs. Heavy cream, a few days past its sell-by date. A desolate bag of spinach whose label says it went bad on Sunday. Bread so hard you wonder if it’s from last Thanksgiving.
The alimentary unthinking, myself included, tends to move right past expiration dates. Last week, I considered the contents of a petite container in the bowels of my fridge that had transcended its best-by date by six weeks. Did I dare to eat a peach yogurt? I sure did, and it was great.
In most households, old items don’t stand a chance. It makes sense for people to be wary of expired food, which can occasionally be vile and incite a frenzied dash to the toilet. Food scientists have been telling us for years, if not decades. Expiration dates are mostly useless when it comes to food safety. Indeed, an enormous portion of what we deem trash is perfectly fine to eat: The food-waste nonprofit ReFED estimated that 305 million pounds of food would be needlessly discarded this Thanksgiving.
Expiration dates, it seems, are hard to quit. But if there were ever a moment to wean ourselves off the habit of throwing out “expired” but perfectly fine items because of excessive caution. Food waste has long been a huge climate issue. Rotting food’s annual emissions in the U.S. approximate 42 coal-fired power plants—and with inflation’s brutal toll on grocery bills, it’s also a problem for your wallet. People throw away roughly $1,300 a year in wasted food.
Zach Conrad, an assistant professor of food systems at William and Mary, told me. In this economy, the only things we should be tossing are the expiration dates themselves.
Expiration dates, part of a sprawling family of labels includes the easily confused siblings “best before,” “sell by,” and “best if used by.” These dates have long muddled our conception of what is edible. They do so by insinuating food has a definitive point of no return, past which it is dead, kaput, expired. You might be, too, if you dare eat it. If only food were as simple as that.
The problem is most expiration dates convey only information about an item’s quality. With the exception of infant formula, where they really do refer to expiration, dates generally represent a manufacturer’s best estimate of how long food is optimally fresh and tasty. What this actually means varies widely, not least because there is no federal oversight over labeling. Milk in Idaho, for example, can be “sold by” grocery stores more than 10 days later than in neighboring Montana. The interim makes no difference in terms of quality. Some states, such as New York and Tennessee, don’t require labels at all.
Date labels have been this haphazard since they arose in the 1970s. At the time, most Americans had begun to rely on grocery stores to get their food and on manufacturers to know about its freshness. Now “the large majority of consumers think that these [labels] are related to safety,” Emily Broad Leib, a Harvard Law professor and the founding director of its Food Law and Policy Clinic, told me. A study she co-authored in 2019 found 84 percent of Americans at least occasionally throw out food close to the date listed on the package.
Quality and safety are two very different things. Plenty of products can be edible, if not tasty, long past their expiration date. Safety, to food experts, refers to an item’s ability to cause the kind of food poisoning sending people to the hospital. It’s “no joke,” Roni Neff, a food-waste expert at Johns Hopkins University, told me.
Consider milk, which is among the most-wasted foods in the world. Milk having already soured or curdled can—get this—still be perfectly safe to consume. (In fact, it makes for fluffy pancakes and biscuits and . . . skin-softening face masks). Broad Leib;
“If you take a sip of that milk, you’re not going to end up with a foodborne illness.”
Adding that milk is one of the safest foods on the market because pasteurization kills all of the germs. Her rule of thumb for other refrigerated items is that anything destined for the stove or oven is safe past its expiration date, so long as it doesn’t smell or look odd. In industry speak, cooking is a “kill step,” one that destroys harmful interlopers if done correctly. And then there is the pantry, an Eden of forever-stable food. Generally, dry goods never become unsafe, even if their flavor dulls. Broad Leib;
“You’re not taking your life into your hands if you’re eating a stale cracker or cereal.”
Of course, it would just be easier if labels were geared toward safety. For the majority of food, the factors are too complex to sum up in a single date. Food is considered unsafe if it carries pathogens such as listeria, E. coli, or salmonella that can cause foodborne illness. These sneak into food through contamination, like when E. coli–tainted water is used to grow romaine lettuce.
Proper storage, which means temperatures colder than 40 degrees Fahrenheit or hotter than 140 degrees Fahrenheit, inhibits their growth (except for listeria, which is particularly scary because it can thrive during refrigeration). It would be extremely difficult for a label to reflect all of this information, especially given that unsafe storage and contamination tend to occur after purchase, in hot car trunks and on unsanitized countertops. But as long as food doesn’t carry these germs to begin with, pathogens won’t suddenly appear the moment the clock strikes midnight on the expiration date. Broad Leib:
“They’re not spontaneous. Your crackers aren’t, like, contracting salmonella from the shelf.” .
There is one category of food that should be labeled. Sometimes referred to as “foods pregnant women should avoid.” It includes certain ready-to-eat products such as deli meats, raw fish, sprouted vegetables, and unpasteurized milk and cheese. Brian Roe, a professor at Ohio State University’s Food Innovation Center, told me. These require extra caution because they can carry listeria, which is invisible to the senses, and are usually served cold. That is, they don’t go through a kill step before being consumed. Experts I spoke with agreed that high-risk foods should be identified as such, because there’s no way to tell if they’ve become unsafe. As things stand, the date label is the only information available, and it is “not helping people protect themselves from that handful of foods,” said Broad Leib. To overcome this setback, efforts are under way in the Senate and the House to replace all date labels with two phrases: best if used by to denote quality and use by for safety.
It is one thing to know that expiration dates are bogus and another to live accordingly. In America, dates have become a tradition we can’t escape, Neff adding that the stickler of each household usually gets to set the rules. And even for more adventurous eaters, date labels serve a purpose: They’re a tool for calibrating judgment, or merely for providing the comfort of a reference point. “There’s something about seeing a number there that we think tells us something that gives us a sense of security,” Neff said. Manufacturers, meanwhile, maintain date labels because they don’t want to risk consumers buying products past their prime, even if they are safe and still (mostly) tasty.
Although there’s no perfect way to know whether food is safe or not, there are better ways than expiration dates to tell. The adage “When in doubt, throw it out” doesn’t cut it anymore, said Neff; if you’re not sure, just look it up. Good tools are available online: She recommends FoodKeeper, an app developed by the U.S. Department of Agriculture, which lets users look up roughly how long food lasts.
The Waste-Free Kitchen Handbook, by the food-waste pioneer Dana Gunders, gives detailed practical advice, such as scraping half an inch below blue-green mold on hard cheese to safely recover the rest. Leftovers require slightly more caution, noted Broad Leib, because reheating, transferring between containers, and frequent touching with utensils (which, admit it, have been in your mouth) introduces more risk for contamination; her recommendation is to eat them within three to five days, and reheat them well—to a pathogen-killing internal temperature of 165 degrees Fahrenheit. And if doing so proves tedious, consider Roe’s take on the old saying: “When in doubt, cover it with panko, fry it up, and give it to your kids.”
Yet for most foods, one tactic reigns supreme: the smell test. Your senses can give you most of the information you need. “If something smells off, you know,” said Broad Leib. Humans evolved disgust because it taught us to avoid the stench of pathogen-tainted food. But because most people are out of practice, they struggle to tell good from bad or don’t trust their senses. To be fair, it can be hard to discern whether weird smells are coming from the milk or the carton. To restore the food knowledge that has been lost since Americans shifted away from agriculture, all of the experts I spoke with supported the revival of home-economics classes—albeit with different branding and no sexism. Teaching students how to handle perishable food means teaching them what perished looks and smells like. Adults can learn this at home, of course, by opening that milk carton and daring to sniff deeply. It may be the first sniff of the rest of your life.
It’s unlikely that we’ll ever return en masse to the pre-1970s idyll of purchasing food directly from farmers or growing it ourselves. Americans are “several generations removed now from agriculture and food production, so we don’t know our food as well as they once did,” Jackie Suggitt, the director of capital, innovation, and engagement at ReFED, told me. A smell rebellion, if you will, can’t restore our severed relationship with food, but hey, it’s a start. The lonely items lingering in one’s post-Thanksgiving fridge may be one inhale away from renewed relevance. If I deigned to sniff that “expired” heavy cream, I might be delighted to encounter a future garnish for pumpkin pie. And what is wilted spinach anyway but a can of artichokes away from dip?

How about those concentric ring impressions on the lids of canned goods?
its not any better for the expiration dates on drugs either. seems the DOD was looking to reconsidering throwing away drugs that are past their expiration date, and it costs many millions of $ to replace them. and it seems mostly has done any testing to validate those date
True. I worked in pharma manufacturing too. Since they started putting dates for pharma usage, too many drugs end up in the garbage or down the drain. Besides being a waste of resource and money, it is hazardous too. Narcotics (pain killers), we would take to the state police station where they had a special facility to personally dispose of the drugs and containers.
If you stare at them long enough, you will enter the twilight zone.
The article is an ok article. Unless you know all the regs on changing a food label, it is a weak article. His only point being the food is not rotten yet.
thanks for this. it’s always nice to have a place to start thinking.
apparently i am a thousnd dollars richer than average because i don’t throw food away, unless it gets moldy. i have a superstious respect for where i think the mycelium have grown that is far deeper than an inch below the flowering part.
the bread i buy..because I have to…has so much respect for sell by dates that it prints them in invisible ink on a part of the package impossible to read without special equipment. it annoys me because i think they are trying to fool me. i use the sell by date as a first guess as to the “baked on” date. i don’t think i have ever gotten a stale loaf, but then i have never gotten a fresh one either. lately i have been priced out of the bread market so i am now getting my bread fresh from the oven…much. MUCH better.
lately i have fallen into the bad habit of eating a bite of peanut butter from a spoon out of the jar…and leaving the jar on the counter for hours instead of “refrigerate after opening” so if you suddenly stop hearing from me you know why.
oh, yeah, i dont buy fresh fruit and veggies from SAFEWAY because they are bred and preserved by better things for better living through chemistry. and also because they taste bad.
and while i don’t trust the hands of Juan Valdez, it’s not because I am a racist.
