Open your fridge right now. Go ahead, I’ll wait. See that yogurt you bought last week? The one with the date stamped on the lid that passed two days ago? You’re probably about to throw it out. And you’d be wrong to do it.
Here’s the thing nobody told you: that date on your food almost certainly has nothing to do with safety. It’s not a deadline. It’s not a warning. In most cases, it’s just a manufacturer’s guess about when a product will taste its absolute best. And the gap between “not at peak freshness” and “will make you sick” is enormous — sometimes weeks, sometimes months, sometimes years.
More than 90 percent of Americans throw away perfectly good food because they misread these labels. The average family of four wastes several hundred dollars a year doing this. And the whole system is essentially made up.
There’s No Federal Law Requiring Expiration Dates
This is the part that shocks people. The federal government does not require date labels on food. Not on meat. Not on dairy. Not on canned goods. Not on anything in your pantry. The single exception? Infant formula. That’s it. That’s the only food product in America where the date on the package is federally mandated and actually tied to safety.
Everything else — the “best by” on your cereal, the “sell by” on your milk, the “use by” on your deli meat — is voluntary. Manufacturers choose whether to put dates on. They choose what phrase to use. They choose how to calculate the date. There’s no standardized method, no required testing, no oversight.
Let that sink in. The dates that convince you to throw away billions of dollars worth of food every year aren’t regulated by anyone.
“Sell By” Dates Were Never Meant for You
Walk into any grocery store and you’ll see “sell by” dates everywhere — on milk cartons, packages of chicken, containers of deli salads. Most people look at that date and think: this is when the food goes bad. Don’t eat it after this.
Wrong. A “sell by” date is a stock rotation tool. It’s a note from the manufacturer to the store, telling employees when to pull the product from the shelf so there’s still plenty of shelf life left after you buy it. It was never designed to communicate anything to consumers. You were never supposed to be making decisions based on it. Experts say that sell by dates confuse people into discarding food way too early — which is exactly what happens millions of times a day across the country.
The same goes for “best if used by.” It means: this is when the manufacturer thinks the product will taste its best. Not when it becomes dangerous. A cracker that’s past its “best by” date might be slightly less crispy. It’s not going to hurt you.
State Laws Are a Total Mess
Since there’s no federal standard, states have filled the void with their own rules. And those rules are wildly inconsistent.
In Montana, milk has to be sold within 12 days of pasteurization. Cross the border into Idaho, and that same milk — pasteurized the same way, stored the same way — can be sold for 23 days. Same milk. Nearly double the sell window. The science didn’t change. The state line did.
One state requires dates on eggs. Another requires them on cream but not milk. Texas demands dates on shellfish. Utah doesn’t. It’s a patchwork that has nothing to do with food science and everything to do with when various state legislators happened to care about the issue.
This inconsistency is itself proof that the dates aren’t really about safety. If they were, you’d expect some agreement. Instead, it’s chaos.
How Long Food Actually Lasts (It’s Longer Than You Think)
Food safety researchers at the University of Georgia have studied how long common foods stay safe past their labeled dates, and the answers are eye-opening.
Milk lasts three to seven days beyond its sell by date as long as your fridge is at or below 40°F. Eggs are safe to eat three to five weeks after purchase — even if the sell by date passed a while ago. Hard cheeses like cheddar? If you see mold, just cut off an inch around and below the spot and eat the rest. (Soft cheeses are different — toss those if they’re moldy.) Low-acid canned goods like beans and corn can last up to five years when stored properly. High-acid canned foods like tomatoes are good for 12 to 18 months.
Bread past its best by date? It goes stale before it becomes unsafe. Stale bread isn’t dangerous. It’s just not great for sandwiches. Make croutons.
The USDA’s FoodKeeper app — which is free — gives specific storage timelines for hundreds of products. Some of the entries will shock you. Certain items can be consumed years past the date on the package.
This Confusion Costs Americans Billions Every Year
In 2023, Americans wasted over 3 billion pounds of food — roughly $7 billion worth — due to date label confusion alone. That’s not total food waste. That’s just the portion thrown out because someone looked at a date and made the wrong call.
The bigger picture is even worse. America throws away nearly 60 million tons of food every year, close to 40 percent of the entire food supply. The value? Around $218 billion. That’s the equivalent of 130 billion meals going into trash cans and dumpsters.
A 2025 survey found that 88 percent of consumers throw out food near the package date at least occasionally. The average American household spends about $1,300 a year on food that ends up wasted. A family of four tosses roughly $1,600 in produce alone.
Meanwhile, nearly 35 million Americans — including 10 million children — don’t have enough to eat.
The Words on the Label Actually Matter More Than the Date
A 2025 study out of Alabama and New York tested how 200 people responded to different label phrases on identical products — turkey deli meat and spaghetti sauce. The products were the same. Only the wording changed.
People who saw “use by” planned to waste more food than people who saw “best by” — even though the product inside the package was identical. The phrase “use by” triggered more fear, more caution, more throwing away. “Best by” gave people permission to keep eating.
The study also found something interesting about personality. People who are more loss-averse — more afraid of losing something than excited about gaining something — waste more food regardless of what the label says. For those people, any date creates anxiety, and anxiety creates waste.
This tells us something important: the problem isn’t just bad labels. It’s how our brains react to dates and deadlines. We’ve been trained to treat stamped numbers like gospel.
California Is About to Change the Rules
Starting July 1, 2026, California will become the first state to ban “sell by” dates on food products. Going forward, only two label types will be allowed: “best if used by” for quality, and “use by” for safety. That’s it. No more “sell by.” No more “enjoy by.” No more “packaged on.”
It’s a big deal because California’s market is so massive that manufacturers often adjust nationwide rather than make separate packaging for one state. When California banned certain food additives, the rest of the country felt it almost immediately. The same thing could happen here.
Researchers estimate that standardizing date labels across the country would save consumers $3.8 billion a year. Most of that goes straight back into household budgets — people simply buying less food they’ll end up throwing away.
What You Should Actually Do
Stop treating dates like deadlines. The date on most food products is a quality suggestion, not a safety warning. Your eyes and nose are better tools than a stamped number decided by a marketing team months ago.
Here’s a simple rule: if it doesn’t look off, smell off, or taste off, it’s almost certainly fine. That goes for dairy, meat, canned goods, bread, condiments — pretty much everything.
Download the USDA FoodKeeper app. It’s free and it gives real storage timelines based on actual food science, not a manufacturer’s conservative guess designed to get you to buy more product sooner.
Use the “first in, first out” method in your fridge and pantry — older items in front, newer items in back. Label leftovers with the date you cooked them using a piece of tape and a marker. Freeze things before they go bad rather than letting them sit until you feel guilty enough to throw them out.
And maybe most importantly, stop feeling like you’re doing something risky by eating food past its date. You’re not being reckless. You’re being rational. The system that told you otherwise was broken from the start.
