Every year, Americans throw away roughly 4.2 billion eggs because they're unsure whether they're still safe to eat. The truth? Eggs last far longer than most people think — and a few simple tricks can help you stop wasting them entirely.
How Long Do Eggs Actually Last?
| Storage Method | Shelf Life |
|---|---|
| Fridge (in carton, 35-40 °F) | 3 – 5 weeks past purchase |
| Fridge (hard-boiled) | Up to 1 week |
| Counter (unwashed, farm-fresh) | Up to 2 weeks |
| Freezer (beaten, in container) | Up to 1 year |
The USDA recommends using eggs within 3 to 5 weeks of purchase when stored in the refrigerator. But that sell-by date on the carton? It's a store-facing date, not an expiration date. Eggs are often perfectly good for another 2-3 weeks after that.
The Float Test: A 30-Second Freshness Check
Fill a bowl with cold water and gently place the egg in:
- Sinks and lies flat: Very fresh (laid within the last week)
- Sinks but stands on one end: Still good, but use soon (2-3 weeks old)
- Floats: Toss it — gases have built up inside, indicating spoilage
This works because eggshells are porous. As eggs age, moisture escapes and air seeps in, making older eggs more buoyant.
5 Tips to Make Eggs Last Longer
- Keep them in the original carton — it protects against odor absorption and moisture loss
- Store on a middle shelf, not the door — the door is the warmest, most temperature-variable spot
- Don't wash store-bought eggs — they have a protective coating applied during processing
- Keep the fridge at 35-40 °F (1.7-4.4 °C) — any warmer accelerates spoilage
- Freeze extras — crack into ice cube trays, freeze, then transfer to bags for up to a year
How to Tell If an Egg Has Gone Bad
Beyond the float test, trust your nose. A bad egg has an unmistakable sulfur smell — you'll know immediately when you crack it. If the white is pink, green, or iridescent, discard it. A cloudy white is actually a sign of freshness, not spoilage.
