Ah! This is a classic grocery-store insider tip—many people look at the wrong date on egg cartons, which can actually affect freshness. Let’s break it down carefully:
The Important Date on Egg Cartons
Egg cartons usually have two dates, and not all are equally meaningful:
- “Sell-By” Date (or “Best Before”)
- This is the date the store should sell the eggs by.
- Eggs can often remain good for 3–5 weeks after this date if stored properly in the fridge.
- “Pack Date” / Julian Date
- Some cartons show a three-digit number (001 = January 1, 365 = December 31).
- This tells you when the eggs were actually packed—and gives a more accurate idea of freshness than the sell-by date.
- “Expiration Date”
- Often used interchangeably with “best if used by.”
- The key is: eggs may still be safe to eat after this date if they’ve been refrigerated consistently.
Insider Tip:
- The freshest eggs are the ones packed most recently, not just the ones with the farthest expiration date.
- Shake test / float test:
- Fill a bowl with water and gently place an egg in it.
- Fresh eggs sink; eggs that float are old and should not be eaten.
💡 Extra Notes:
- Store eggs in the main fridge compartment, not the door, to maintain a consistent temperature.
- Keep them in the carton to protect from absorbing odors and prevent moisture loss.
