🧠 The Truth About Expiration Labels: They’re Not All the Same
Most people think “expired = unsafe.”
But that’s a myth.
In reality, only infant formula is federally required to have a true expiration date.
Everything else?
It’s mostly about peak quality, not safety.
Here’s what each label actually means:
Label
What It Really Means
What You Should Do
✅ “Best By” or “Best Before”
Manufacturer’s guess at peak flavor, texture, and freshness
✅ Still safe to eat after this date—just may taste slightly stale or dull (e.g., chips, cereal, canned goods)
⚠️ “Use By”
Last date for optimal quality and safety—common on perishables like meat, dairy, yogurt
⚠️ Use caution. Best to follow this date, especially for raw meats and seafood. But still check smell, color, texture before tossing
🏪 “Sell By”
For store inventory only—tells retailers when to remove from shelves
🛒 Safe to eat for days (or weeks) after this date if stored properly (e.g., milk often good 5–7 days past “Sell By”)
🛑 “Expires On”
Rare. Used for items where potency/safety declines over time (infant formula, medications, some supplements)
🛑 Follow strictly. Don’t consume after this date
💬 Key Insight: There is no federal standard for most expiration dates in the U.S.—manufacturers set them however they want.
🍱 How Long Can You Actually Keep Common Foods?
Don’t throw it out—check this guide first:
Food
How Long After Date?
Signs It’s Gone Bad
Canned Goods (soup, beans, veggies)
✅ 1–5 years past “Best By”
Rust, bulging lid, foul smell when opened
Dry Pasta & Rice
✅ 1–2 years past
Bugs, musty smell, dampness
Breakfast Cereal
✅ 6–12 months past
Stale taste, soft texture
Eggs
✅ 3–5 weeks past “Sell By”
Float test: Fresh eggs sink; bad ones float
Milk
✅ 5–7 days past “Sell By”
Sour smell, curdling
Yogurt
✅ 1–2 weeks past “Use By”
Mold, separation, off smell
Cheese (hard) (cheddar, Parmesan)
✅ Months past (if mold-free)
Cut off small mold spots; rest is safe
Bread
✅ 5–7 days past (freeze if longer)
Mold = toss entire loaf
Frozen Foods
✅ Indefinitely (quality drops after 6–12 months)
Freezer burn = dry, but still safe
💡 Pro tip: When in doubt, sniff it, look at it, then taste a tiny bit. Your senses are better than any label.
🔬 Why Most Food Doesn’t Suddenly Spoil on the “Expiration Date”
Food spoils due to:
Bacteria growth
Moisture loss
Oxidation
Temperature exposure
But these factors depend on how food is stored—not just the calendar.
A can of beans stored in a cool, dry pantry will last years.
The same can left in a hot garage? Might spoil much sooner.
👉 The printed date doesn’t account for your storage conditions.
