The Truth About Expiration Dates: What Food Companies Don’t Explain

Standing in the kitchen squinting at a date stamped on a yogurt lid is a pretty universal experience. Most people assume that date is a hard safety cutoff, set by some kind of federal standard.

It is not, and the gap between what people assume and what is actually true costs a staggering amount of food every year. The actual rules behind those dates are a lot looser than the label makes them look.

Almost None of It Is Federally Required

Outside of infant formula, the federal government does not require food packaging to carry a date at all. The decision to print a date, and which phrase to use, is almost entirely up to the manufacturer.

That means one company’s “best by” and another company’s “use by” printed on similar products might mean completely different things, even though both look equally official. Nothing about the format is standardized across the industry.

Most Dates Are About Taste, Not Safety

The overwhelming majority of date labels are quality indicators, not safety warnings, meaning the food is very likely still fine to eat once that date passes. Advocacy groups tracking this issue estimate that roughly ten percent of all food wasted in American homes comes down to people misreading a date label as a safety deadline.

A carton of eggs or a bag of chips past its printed date has usually just started to lose some peak freshness, not turned dangerous overnight. Genuine safety dates are far less common than people assume.

Trusting Your Senses Still Works

Food safety experts consistently point back to the same basic test, look at it, smell it, and taste a small amount before deciding. A food safety specialist at the University of Georgia put it simply, saying that if a food looks fine, smells fine and tastes fine, it is probably fine.

Shelf stable items like canned goods can often last for years past their printed date as long as the can itself is undamaged. The date on the label was never designed to be the final word on whether something is actually still good.

None of this means every date on a package is meaningless, since a genuine use by date on something like raw meat is worth taking seriously. It just means the vague quality dates on most other food deserve a lot less panic than they usually get.
