What You Really Need to Know About Food Expiration Dates (Stop Wasting Food!)

No — food is usually still safe

“Use By”

Last date for best quality (common on perishables)

Not necessarily — check smell/texture

“Sell By”

For store inventory — tells retailers when to pull stock

Never — this is not a consumer date

Key insight: These dates assume proper storage. If you left milk out overnight, it doesn’t matter what the label says—it’s spoiled.

When Food Is Actually Unsafe (Trust Your Senses!)

Expiration dates don’t override reality. Always check for signs of spoilage:

Smell: Sour, rancid, or “off” odors = toss it

Texture: Slimy meat, moldy cheese, fizzy juice = unsafe

Color: Green beef, gray poultry, or cloudy liquids = warning signs

Taste: If it tastes wrong, spit it out (don’t risk it!)

Golden rule: When in doubt, throw it out—but only after using your senses first.
