Clearer labeling helps people understand food is often safe well after the date passes
On the first day of July 2026, California quietly redrew the line between what we fear and what we waste, banning the phrase 'sell by' from food packaging in favor of clearer language that distinguishes quality from safety. For decades, three ambiguous words on a label have driven families to discard perfectly edible food, costing them money and burdening landfills with the ghost of misunderstanding. This regulatory act is, at its heart, not about food — it is about the cost of unclear communication, and the quiet power of choosing better words.
- Millions of Californians have been throwing away safe, edible food for years — not because it spoiled, but because they couldn't decode what the date on the package actually meant.
- As of July 1, 2026, the phrase 'sell by' is legally banned in California, forcing manufacturers and major retailers like Walmart to overhaul labels, retrain staff, and revise inventory systems statewide.
- The new law draws a clear line: 'best by' signals a decline in quality, while 'use by' signals a genuine safety concern — a distinction that was always meaningful but never legally enforced.
- California's move is being watched by federal regulators and other states, as the U.S. still lacks a national standard for food date labeling, creating a fragmented system that burdens manufacturers and confuses consumers alike.
- If the law succeeds in reducing premature food disposal, it could trigger a national reckoning with how the food industry communicates — turning a small label change into a large environmental and economic shift.
On July 1, California's grocery stores began pulling and relabeling products — not because the food had spoiled, but because certain words on the packaging had become illegal. The offending phrase: 'sell by,' a label that has confused American shoppers for decades.
The confusion has always been real. A 'sell by' date tells retailers when to rotate stock, but says nothing meaningful to the consumer about whether food is safe to eat. Meanwhile, 'best by' suggests peak quality, and 'use by' signals an actual safety threshold. Without understanding these distinctions, families have routinely discarded perfectly good milk, yogurt, and packaged goods — contributing to millions of tons of annual food waste.
California's new law resolves the ambiguity by eliminating 'sell by' entirely. Manufacturers must now choose between 'best by' — for products that may decline in quality but remain safe — and 'use by,' reserved for items where safety genuinely becomes a concern after the listed date. Major retailers like Walmart have already revised inventory systems, updated labeling machinery, and retrained staff to comply across hundreds of California locations.
The law is drawing attention well beyond state lines. The United States has no national standard for food date labeling, meaning the same product can carry different labels depending on where it's sold — a fragmentation that frustrates manufacturers and misleads consumers. Federal regulators have been weighing their own guidance, and California's move may accelerate that process.
What's striking about this legislation is that it targets a problem of communication, not contamination. The American food supply is largely safe — the trouble is that consumers don't know it, and that uncertainty drives waste. By standardizing the language on packages, California is wagering that clearer words will lead to smarter choices, and that a small shift in labeling could carry surprisingly large consequences.
On July 1, California's grocery stores began pulling products from shelves and relabeling them. Not because the food had spoiled, but because the words on the package were about to become illegal. The culprit: those three ambiguous words that have confused shoppers for decades—'sell by.'
For years, American consumers have stood in supermarket aisles squinting at date labels, uncertain what they actually meant. A 'sell by' date tells a retailer when to remove a product from the shelf to ensure freshness, but it says nothing definitive about whether the food is safe to eat. A 'best by' date suggests peak quality but doesn't mean the product is unsafe after that point. A 'use by' date carries more weight—it's the one that actually matters for food safety. The confusion between these three phrases has cost families money and contributed to a staggering amount of food waste. Consumers, unsure which date meant what, have thrown away perfectly good milk, yogurt, and packaged goods rather than risk it.
California's new law eliminates the ambiguity by banning 'sell by' labels entirely. Starting July 1, 2026, manufacturers and retailers in the state must choose between 'best by' or 'use by'—language that more clearly signals the distinction between quality and safety. The 'best by' label can be used when a product's flavor or texture may decline after that date, but it remains safe to consume. The 'use by' label is reserved for items where safety genuinely becomes a concern. This single change, while it might seem minor to someone who has never thought about date labels, represents a significant shift in how the food industry communicates with consumers.
Major retailers like Walmart have already begun adjusting their operations to comply. The company, which operates hundreds of stores across California, has had to revise inventory systems, update labeling machinery, and retrain staff to ensure compliance. For a chain of that scale, the logistical lift is substantial. But the motivation extends beyond regulatory obligation. Food waste has become a visible problem—both economically and environmentally. When consumers misunderstand date labels and discard food prematurely, it's not just money lost at the household level. It's millions of tons of food ending up in landfills each year, along with all the water, energy, and resources that went into producing it.
The California law is being watched closely by other states and by federal regulators. There is no national standard for food date labeling in the United States, which means a product might carry different labels depending on which state it's sold in. This fragmentation creates headaches for manufacturers who operate across state lines. If California's approach proves effective at reducing waste and clarifying consumer behavior, other states may follow. The Food and Drug Administration has been considering its own guidance on standardized labeling, and California's move could accelerate that conversation.
What makes this law particularly interesting is that it addresses a problem that isn't primarily about food safety—it's about communication. The food supply in America is already quite safe. The issue is that consumers don't know it, and that uncertainty drives waste. By making the language on packages clearer and more consistent, California is betting that people will make smarter decisions about what to keep and what to throw away. It's a small intervention with potentially large ripple effects.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter what three words appear on a yogurt container? Isn't the date the real information?
The date is the information, yes—but the words change what the date means. 'Sell by' is for the store. 'Best by' is about quality. 'Use by' is about safety. Most people don't know that distinction, so they treat all three the same way: as a hard deadline.
And they throw food away because they're not sure?
Exactly. If you see 'sell by' and you're not certain what it means, you err on the side of caution. You toss it. Multiply that across millions of households, and you're talking about enormous waste.
So this law is really about reducing waste, not about food safety?
Partly. But clearer labeling also helps people understand that food is often safe well after the 'sell by' date passes. It's about aligning what people think with what's actually true.
Will other states do the same thing?
That's the real question. If California shows this works—if waste goes down and people feel more confident—then yes, you'll likely see other states move in that direction. And the FDA might eventually set a national standard.
What about the retailers? Is this expensive for them?
It requires changes to labeling systems, inventory tracking, and staff training. For a company like Walmart, that's significant. But they're also seeing it as an opportunity to reduce their own waste and align with consumer expectations about sustainability.
