Real talk: how many times have you tossed a perfectly good yogurt, a bag of chips, or a block of cheese because the date on the label said “expired” — even though it looked, smelled, and probably tasted totally fine? You are not alone, and it turns out the confusing mess of stamps on our groceries has been quietly costing American shoppers a fortune for years. But 2026 is bringing a change that could finally clear things up, starting with one very unexpected state.
Wait, “Best By” Doesn’t Actually Mean What You Think
Here’s the twist almost nobody knows: there is no federal law requiring date labels on food (aside from infant formula). That means every manufacturer gets to make up its own phrase, and right now there are an estimated 50 different labels floating around U.S. grocery shelves — “best by,” “best if used by,” “sell by,” “use by,” “expires on,” and more. None of them are standardized, and most of them aren’t even about safety.
“Best By” or “Best If Used By” is purely a quality call from the manufacturer. It’s their way of saying “this is when we think it tastes its absolute best,” not “this will make you sick after this date.” “Sell By” isn’t even meant for you — it’s a stocking cue for the store, so employees know when to rotate shelves. “Use By” is the one that actually matters most for safety, especially on perishables like deli meat, soft cheese, and fresh poultry.
“There are about 50 different date labels used across the country, and none of them are federally regulated.” — food safety researchers, as reported by consumer advocacy group PIRG
California Just Blew Up the Confusing System
As of July 1, 2026, California became the first state to require food manufacturers to simplify things down to just two phrases on products sold there: “BEST IF USED BY” for quality, and “USE BY” for safety. That’s it — no more guessing games with a dozen variations. Food safety advocates are hoping other states (and eventually the whole country) follow California’s lead, since studies tie label confusion directly to how much food ends up in the trash. Estimates suggest a huge chunk of the food waste in American households happens simply because people don’t understand what the date on the package is actually telling them.
If you shop at Aldi, Costco, Trader Joe’s, or order through Amazon grocery, this matters because private-label and store-brand items are notorious for using whatever date phrasing the manufacturer feels like. We’ve already decoded the secret codes hiding on your grocery labels, and this expiration date confusion is basically round two of the same problem: the label isn’t lying to you, but it also isn’t telling you the full story.

So When Should You Actually Toss It?
Here’s the shopper-friendly cheat sheet: for shelf-stable stuff like canned goods, pasta, rice, and most snacks, a “best by” date that’s passed is almost never a safety issue — it just means texture or flavor might not be peak-fresh. Trust your nose and eyes first. For dairy, eggs, and deli items, give it a sniff before you panic-toss it; many stay safe for days past the printed date if stored properly. Pay closer attention to anything with a true safety-based “use by” date on raw meat, poultry, seafood, or ready-to-eat items — that’s a real bacterial-risk warning, not just a flavor call.
Combine this with a few of the grocery shopping tricks we’ve rounded up before and you’ll waste less food and less money in the same trip. And if you’ve ever wondered why certain items get slapped with a clearance sticker seemingly overnight, that ties right back into this — check out our breakdown of the secret sticker code stores use for markdowns to squeeze even more savings out of items that are perfectly fine to eat.
The Bottom Line for Smart Shoppers
Understanding the difference between a quality date and a safety date is basically a free superpower: fewer trips to the store, less cash tossed in the trash, and a fridge that gets used up instead of cleaned out. Other states will likely follow California’s lead soon — but you don’t have to wait. Next time you’re staring down a “best by” date on your Aldi, Costco, or Trader Joe’s haul, take a beat before you toss it. Your wallet will thank you.
