does use by date include that day?

Ever stood in front of your fridge, holding a yogurt container on its “use by” date, wondering, “Can I still eat this?” You’re not alone. Food expiration labels are confusing—some are strict deadlines, while others are just suggestions.

After years of trial and error (including a regrettable hummus incident), I’ve cracked the code on food dating. Here’s everything you need to know about “use by,” “best by,” and “sell by” dates—plus when to toss food and when it’s still safe.

✔ Safe to Eat (Usually) on the “Use By” Day

Not all foods turn into biohazards the second the clock strikes midnight on their expiration date. Here’s what’s usually fine:

Milk & Yogurt

  • Rule: If it smells and looks normal, it’s likely safe.
  • Pro Tip: Pasteurized milk often lasts 5-7 days past its printed date if refrigerated properly.
  • My Hack: Smell it before pouring—saved me from many cereal disasters.

Packaged Greens & Salads

  • Rule: No slime? No weird smell? You’re good.
  • Warning: Pre-washed greens can be sneaky—check for excess moisture.

Eggs

  • The Float Test:
  1. Fill a bowl with water.
  2. Gently place the egg in.
  • Sinks flat? Fresh.
  • Stands upright? Still okay, but use soon.
  • Floats? Toss it.
  • Storage Tip: Keep eggs in the back of the fridge (not the door) for maximum freshness.

❌ Be Cautious After the “Use By” Date

Some foods are not worth the risk. Here’s when to be extra careful:

Raw Meat & Poultry

  • 1-2 days past? Maybe if stored properly and smells fine.
  • Signs it’s bad: Stickiness, slime, or a weird sheen.
  • Lesson Learned: I grilled chicken right on its “use by” date once—big mistake.

Deli Meats & Soft Cheeses

  • Listeria risk: If the package is bloated or smells off, don’t risk it.
  • Hard cheeses (like cheddar): Just cut off moldy parts.

Seafood

  • Fresh fish should smell like the ocean—not “fishy.”
  • Shrimp turning gray? Toss it immediately.

My Personal “Oops” Moment: The Great Hummus Incident

I ignored a one-day-past “use by” date on store-bought hummus. Big mistake.

  • 3 AM: Woke up with stomach cramps that felt like a WWE match in my gut.
  • Why it happened: High-moisture, low-acid foods (hummus, guacamole, fresh salsa) spoil fast.
  • Now I:
  • Freeze half of dips right after buying.
  • Never push “use by” dates on perishable spreads.

Pro Tip: Decoding “Best By” vs. “Sell By”

Not all date labels mean the same thing! Here’s the breakdown:

“Best By” / “Best Before”

  • About quality, not safety.
  • Still safe after? Usually, yes.
  • Dry pasta? Fine years later.
  • Canned beans? Safe indefinitely if the can’s intact.

“Sell By”

  • For stores, not consumers.
  • How long after?
  • Dairy: 5-7 days past.
  • Eggs: 3-5 weeks past (use the float test!).

“Use By”

  • Last day for peak quality on perishables.
  • When to obey: Baby formula, fresh juices, prescription meds.

How to Extend Shelf Life Like a Pro

Smart Storage Tricks

Keep fridge at 37°F (3°C) or below—most people’s fridges are too warm.
Freeze bread, cheese, and sauces before they expire.
Store herbs in a glass of water (like flowers) to keep them fresh longer.

The Sniff Test Rule

  • “When in doubt, throw it out.”
  • Exception: Aged foods (like dry-aged steak) are supposed to smell funky—learn the difference!

Final Verdict: Does “Use By” Include That Day?

Yes—but with caution.

  • On the date? Usually safe if stored properly.
  • After? Depends on the food—when in doubt, trust your senses.
