We’ve all been there—you open the fridge, take out a carton of milk or a package of chicken, check the expiration date, and suddenly wonder: “Is this still safe to eat?” Most of us instinctively toss food the moment it passes its printed date, convinced that eating it past that day is a surefire way to get food poisoning.
Good News: Expiration Dates Don’t Always Indicate Safety
In reality, most expiration dates have nothing to do with food safety. Misinterpreting these labels is one of the biggest reasons Americans waste millions of pounds of food every year. Understanding what expiration dates actually mean can help you:
✔ Waste less food
✔ Save more money
✔ Enjoy fresh meals without second-guessing yourself
Let’s break it down: What do expiration dates really mean? How long do different foods actually last? And how can you tell if something has truly gone bad?
Why Are Expiration Dates So Confusing?
The first thing to know: Expiration dates aren’t regulated consistently across the food industry. Different manufacturers use various terms, making it confusing for consumers.
Here are the three most common date labels found on food products:
Best if Used By
✔ Not a safety date—it’s a quality date.
✔ Food might not taste as fresh after this date, but it’s often still perfectly safe to eat.
✔ Common on packaged goods, snacks, and dairy products.
Use By
✔ Indicates peak quality, as estimated by the manufacturer.
✔ Does not apply to perishables like dairy, eggs, or meat.
✔ Eating food past this date won’t necessarily make you sick, but flavor and texture might decline.
Sell By
✔ For stores, not consumers—tells grocery stores how long to display the product.
✔ If stored correctly, most foods can be eaten well beyond this date.
✔ Often found on meat, dairy, and baked goods.
Bottom Line:
Most food doesn’t magically go bad the day after its expiration date. But because labels aren’t clearly explained, many people treat them as strict deadlines—leading to massive amounts of unnecessary food waste.
How Much Food Are We Wasting Because of Expiration Dates?
Food waste is a huge problem in the U.S. Wasted food accounts for 30–40% of all food produced—that’s 133 billion pounds of food thrown away each year! (Source: USDA)
Why Does This Happen?
Confusion over expiration dates leads people to discard perfectly good food.
It’s costly—wasted food means wasted money.
It’s bad for the environment—rotting food produces methane, a powerful greenhouse gas.
The Consequences of Food Waste:
✔ Water & Energy Waste – Growing, packaging, and transporting food uses huge amounts of resources. Wasting food wastes those resources too.
✔ Higher Grocery Costs – Wasting food means spending more to replace it, driving up household expenses.
✔ Climate Impact – Food rotting in landfills produces methane, a greenhouse gas that contributes to climate change.
The solution? Learn how to properly interpret expiration dates and store food correctly.
How Long Do Common Foods Actually Last?
Think food goes bad the second the date passes? Think again! Here’s how long different foods actually remain safe to eat:
Eggs 🥚
✔ Good for: 3-5 weeks after purchase.
✔ Freshness test: Place in a bowl of water. If it sinks, it’s fresh. If it stands upright, it’s older but still safe. If it floats, toss it.

Chicken & Meat 🍗
✔ Safe for: 1-2 days after the “Sell By” date if refrigerated.
✔ Pro Tip: Freeze meat you won’t cook soon—it’s safe indefinitely in the freezer, though quality may decline after a few months.
Milk 🥛
✔ Safe for: Up to a week past the “Best By” date if it smells and looks normal.
✔ When to toss: If it smells sour or curdles, discard it.
Rice & Pasta 🍚🍝
✔ Safe for: Years if stored in an airtight container in a cool, dry place.
✔ Spoilage signs: Discoloration, bugs, or a bad smell.
Canned Foods 🥫
✔ Good for: Years beyond the expiration date—as long as the can isn’t dented, rusted, or bulging.
✔ Spoilage signs: Off odor, discoloration, or broken seal.
Frozen Foods ❄️
✔ Safe forever at 0°F (-18°C), but quality declines over time.
✔ Look for: Freezer burn—grayish-brown spots caused by moisture loss.
How to Tell if Food Has Gone Bad (Without Expiration Dates!)
Since expiration dates are only guidelines, your senses are your best tools to detect spoilage:
✔ Mold – Fuzzy spots? Toss it.
✔ Bad Smell – Sour, rancid, or off-smells? It’s bad.
✔ Weird Texture – Slimy meat, mushy veggies, curdled dairy? Throw it out.
✔ Unusual Taste – If it tastes off, don’t eat it!
Food Storage Tips to Keep Food Fresh Longer
Want to reduce waste and make groceries last longer? Proper storage is key!
Refrigeration & Freezing
✔ Set fridge to 40°F (4°C) or lower to prevent bacteria growth.
✔ Freeze food properly at 0°F (-18°C) to store it safely for months.
Keep Dry Goods Fresh
✔ Store flour, pasta, and cereal in airtight containers to keep moisture and pests out.
Organize Your Fridge
✔ Top Shelves: Leftovers, beverages, and ready-to-eat foods.
✔ Middle Shelves: Dairy and eggs.
✔ Bottom Shelf: Raw meat (prevents cross-contamination).
Trust Your Senses, Not Just the Date Label: Final Thoughts
The next time you see an expiration date, don’t panic! Instead, remember:
✔ Most dates reflect quality, not safety.
✔ Food lasts longer than you think—if stored properly.
✔ Use your senses (smell, sight, taste) to determine freshness.
By understanding expiration labels, storing food correctly, and trusting your instincts, you can reduce waste, save money, and enjoy fresher meals.
So, before you throw away that milk, yogurt, or chicken, double-check it first—it might still be perfectly fine to eat!
