Across millions of American kitchens, a quiet and costly ritual repeats itself: food deemed expired by a printed date is discarded before it is ever tasted. Yet most of those dates speak to freshness, not safety — a distinction that federal labeling standards have never clearly drawn. In the absence of uniform guidance, consumers are left to interpret a fragmented vocabulary of 'sell by,' 'best by,' and 'use by' as if each phrase carried the same weight, and the result is an enormous, largely preventable loss of food, money, and resources.
Experts: Most Expired Food Labels Are Misleading, Not Safety Markers
Safe food gets thrown away by the ton because people misread what a date actually means.
Mark
Why do manufacturers use different date labels if they all mean the same thing?
Mimi
They don't all mean the same thing, which is exactly the problem. There's no federal rule saying what "best by" versus "use by" actually means. Each company decides. So the same phrase can mean different things on different products.
Mark
But surely people know that dates are just guidelines, not hard rules?
Mimi
Most people don't. When you see a date on food, your instinct is to treat it as a safety deadline. That's what we've been taught. Without clear labeling, there's no way to know the difference between a quality date and an actual safety concern.
Mark
So the food is actually safe to eat after the date passes?
Mimi
In most cases, yes. If it's stored properly and shows no signs of spoilage, it's fine. A yogurt three days past its date is almost certainly safe. But people throw it away anyway because they don't trust their own judgment against the label.
Mark
Who benefits from this confusion?
Mimi
Retailers benefit because they can remove products from shelves without liability concerns. Manufacturers benefit because people buy more frequently. Consumers lose money and waste food. It's a system that works for everyone except the person buying the groceries.
Mark
What would standardization actually change?
Mimi
One clear definition of each phrase, applied everywhere. Then a consumer would know exactly what "best by" means on any product. They could make informed decisions instead of defaulting to throwing food away.
Mark
Is there any real safety risk in eating food past the date?
Mimi
Not if you use your senses. Spoiled food usually smells, tastes, or looks wrong. The date label doesn't tell you anything about whether that specific package has spoiled. It's just a guess based on average storage conditions.
The Pulse
- Millions of households discard safe, edible food every day because date labels are widely misread as safety deadlines rather than quality benchmarks.
- A patchwork of state and manufacturer labeling conventions — with no federal standard governing most foods — leaves consumers with no reliable way to interpret what any given date actually means.
- Retailers compound the confusion by pulling products from shelves early to avoid liability, reinforcing the false impression that printed dates mark a hard line between safe and dangerous.
- The economic burden falls disproportionately on lower-income households, who waste grocery spending they cannot afford to lose yet lack the confidence to trust food past its label.
- Advocates and some manufacturers are pushing toward standardized, science-based labeling, but without federal action the fragmented system — and the waste it generates — continues largely unchanged.
Across millions of American kitchens, a quiet and costly ritual repeats itself: food deemed expired by a printed date is discarded before it is ever tasted.

You check the date on a container of yogurt, see that it passed three days ago, and throw it away without opening it. Multiply that moment across millions of households, and you begin to see what food safety experts call a largely preventable crisis: Americans discarding enormous quantities of perfectly edible food because they misread what a date label actually means.
The misunderstanding is fundamental. Most printed dates — 'sell by,' 'best by,' 'use by' — are quality indicators, not safety markers. They signal when a product will taste its best, not when it becomes dangerous. Yet without clear guidance, consumers treat them as hard deadlines, and safe food gets thrown away by the ton.
Experts trace the problem to the absence of federal standards. Unlike medications or infant formula, most food products are labeled according to whatever system each state or manufacturer chooses, producing a vocabulary that no shopper can reliably decode. Retailers, wary of liability, remove products from shelves well before any real safety concern arises, reinforcing the impression that dates are strict cutoffs. The economic toll falls hardest on households with tight budgets, who can least afford to discard groceries.
The science tells a different story. Most foods remain safe well past their printed dates when stored properly — canned goods, frozen items, and even perishables like yogurt and milk often last days or weeks longer than their labels suggest. Smell, taste, and appearance are far more reliable guides than any printed date.
Some manufacturers and states are beginning to move toward clearer, more consistent labeling, but without federal action the patchwork endures. The fix, experts say, is straightforward. What remains missing is the will to carry it out.
You buy a container of yogurt. You check the date. It passed three days ago. You throw it away without opening it. Multiply that moment by millions of households across the country, and you begin to see the scale of what food safety experts describe as a largely preventable crisis: Americans discarding enormous quantities of perfectly edible food because they misread what a date on a label actually means.
The problem starts with a fundamental misunderstanding. Most of the dates printed on food packaging—"sell by," "best by," "use by"—are not safety markers. They are quality indicators, signals from manufacturers about when a product will taste and perform at its peak. Yet consumers, lacking clear guidance, treat them as hard deadlines. The result is that safe food gets thrown away by the ton, wasting money, resources, and calories that could have been eaten.
Experts point to the absence of federal standards as the root cause. Unlike medications or infant formula, which have federally mandated expiration date requirements, most food products are labeled according to whatever system each state or manufacturer chooses. One company might print "best by," another "sell by," a third "use by." A shopper standing in front of a refrigerator case sees these different phrases and has no reliable way to know what they mean or how seriously to take them. The confusion is not accidental; it is built into a system that has never been standardized.
This inconsistency creates a cascade of waste. Retailers, uncertain about liability and wanting to appear cautious, often remove products from shelves well before any actual safety concern arises. Consumers, seeing those products gone and having no better information, assume the dates are strict safety cutoffs. Food that is still wholesome gets discarded. The economic impact falls hardest on households with tight budgets, who cannot afford to throw away groceries, yet often lack the confidence to ignore a date label.
The science is clear: most foods remain safe well past their printed dates if stored properly. Canned goods, dried goods, frozen items—these can last far longer than their labels suggest. Even perishables like yogurt, milk, and deli meats often remain safe for days or weeks beyond the date, depending on storage conditions and how they have been handled. A person can usually tell by smell, taste, or appearance whether something has actually spoiled. The date label, by contrast, tells you nothing about the specific conditions under which that particular package has been stored.
Food safety experts argue that standardizing date labeling would reduce confusion and waste without compromising safety. A uniform system—one clear definition of what each phrase means, applied consistently across all products and all states—would give consumers reliable information and the confidence to make their own judgments about whether food is still good. It would also align consumer behavior with actual food safety science rather than with arbitrary manufacturer conventions.
The conversation around this issue is beginning to shift. Some manufacturers have started moving toward clearer labeling. Some states have begun exploring standardization. But without federal action, the patchwork remains. In the meantime, millions of people continue to throw away food that is safe to eat, paying more than they need to and contributing to a waste stream that strains landfills and resources. The fix is straightforward. What is missing is the will to implement it.
