Understanding Food Labels: Beyond the Expiry Date

Food labels are not as straightforward as they seem. Printed dates are manufacturer estimates, not hard safety rules. Learning what each label means — and when to trust your senses instead — saves food and money.

Sell-by: for the store, not you

"Sell-by" tells retailers how long to display a product. It is not a safety date. Milk is typically fine 5 to 7 days past its sell-by date if kept cold. Eggs last 3 to 5 weeks.

Best-by: quality, not safety

"Best-by" indicates when a product is at peak flavor or texture. Cereal, pasta, and canned goods are almost always safe well past this date. The quality may decline slightly — a cracker might be less crisp — but it is not dangerous.

Use-by: the closest thing to a deadline

"Use-by" is the most conservative label. Take it seriously for fresh meat, poultry, fish, and ready-to-eat refrigerated foods. For shelf-stable goods, it is still mostly about quality, not danger.

Packaged on or born on dates

Some items show when they were packaged rather than when they expire. Bread, meat, and some dairy products use these. They are helpful for judging freshness in stores, but they do not tell you when something has actually gone bad.

Trust your senses first

Smell, look, and taste a small bite. Sour milk, rancid meat, moldy soft cheese, or slimy vegetables are hard noes. If it looks fine, smells fine, and tastes fine, it almost certainly is fine — regardless of what the label says.

Smarter tracking with FridgeSpy

FridgeSpy uses category-based expiry logic rather than rigid printed dates. It nudges you based on how an item actually behaves, not an arbitrary stamp — so you waste less without gambling on safety.
