Is Your Egg Still Good? Simple Ways to Tell in Seconds

Even if an egg passes the float test, you should always perform a quick smell check after cracking it.

Fresh eggs have almost no smell.

Spoiled eggs usually produce a strong odor similar to:

• Rotten sulfur

• Ammonia

• Sour milk

If the egg smells unpleasant—even slightly—it’s best to discard it immediately.

Helpful tip: Crack eggs into a separate small bowl first before adding them to your recipe. This prevents one bad egg from ruining the entire dish.

3. The Appearance Test

Another easy way to judge freshness is by examining the egg once it’s cracked.

Signs of a fresh egg

• Yolk: Round, firm, and slightly raised

• Egg white: Thick and slightly gel-like near the yolk

Signs of an older egg

• Egg white spreads widely and looks watery

This doesn’t always mean the egg is spoiled—it may simply be older and better suited for baking or scrambling rather than frying.

Warning signs

If you notice any of these, discard the egg:

• Pink or greenish egg whites

• Shiny or unusual rainbow coloring

• Strong unpleasant odor

Small blood spots are harmless and can simply be removed.

What About the Expiration Date?

Many people assume eggs must be thrown away immediately after the printed date on the carton. In reality, eggs often remain safe for several weeks after that date if they are stored properly.

Here’s what those dates mean:

• Pack date: The day the eggs were washed and packaged

• Sell-by date: A guideline for stores, not necessarily the final safe date for consumers

When kept refrigerated at 40°F (4°C) or lower, eggs usually stay good for 3–5 weeks after packaging.

For best results, store eggs inside the refrigerator rather than in the door, where temperatures change more frequently.
