What does that package date mean?
Many dates describe expected quality, but the label, product, storage history and package condition all belong in the decision.
Start with the exact wording
FDA and USDA recommend “Best if Used By” as a quality-based phrase: after that date, quality may decline, but the food may still be consumable. Other phrases remain in use, and infant formula has specific federal date requirements. Follow product-specific instructions and any “keep refrigerated” statement.
| Wording | Usually communicates | Your next check |
|---|---|---|
| Best if Used By / Best By | Peak quality | Storage history and package condition |
| Sell By | Retail inventory guidance | Product type and safe storage |
| Use By | Maker’s recommended last date for peak quality; rules vary by product | Follow applicable product instructions |
Condition can overrule the calendar
Do not use food from containers that are leaking, bulging, badly dented at seams, spurting liquid or unusually rusted. Discard food with an off odor, color or texture; never taste food to test safety. When a perishable food has been held too warm, a future printed date does not make it safe.
Rotate by visibility
Place older undamaged packages where they will be used first, but do not hide new stock behind them without recording the quantity. Keep a small “use soon” zone for quality dates instead of treating the entire pantry as urgent.
