Float test

Eggs past the expiration date
Best-by and sell-by
FoodKeeper gives unopened eggs 3–5 weeks 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
For perishable eggs, the storage clock matters more than the label: if it has been in the fridge longer than 3–5 weeks, discard it even before the printed date.
How to keep eggs fresh longer
- Keep eggs in their carton on an inside shelf, not the door.
- Store at 40°F (4°C) or below; do not wash them before storing.
- Refrigerate hard-boiled eggs within 2 hours of cooking.
