Date labels

Best-by and use-by dates on duck fat

Best-by and sell-by

FoodKeeper gives unopened duck fat 30 days in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.

Past the date

Duck fat past its best-by date is usually safe if stored well; check smell, look and taste before using.

Storage tips

How to store duck fat

  • Refrigerate after opening unless the label says otherwise.
