How Long Are Eggs Good After the Sell-by Date

話題沸騰中の How Long Are Eggs Good After the Sell-by Dateについて、多角的な視点をご紹介しています。

Want to play detective? Try the float test. Fill a bowl with cold water. Gently drop in an egg. If it sinks and lies flat on its side—super fresh. If it stands upright on the bottom—still good, but use it soon. If it floats to the top—toss it.

Why does this work? It’s all about air. Eggs are porous. Over time, they lose moisture and take in air through the shell. A floating egg has too much air inside. That means it’s old, and possibly spoiled.

This test is ridiculously simple. It’s also strangely satisfying. You’ll feel like a science nerd. Try it next time you’re bored.

The Sniff Rule: Your Nose Knows

There’s another trick. The sniff test. Crack an egg into a clean bowl. Give it a quick sniff. If it smells like nothing—you’re golden. If you get a whiff of sulfur or rotten garbage—run.

Your nose is a powerful tool. It evolved to detect bad food. Trust it. A bad egg smells awful. There’s no mistaking it. It’s a smell you won’t forget.

Fun twist: Fresh eggs have almost zero smell. So if you’re sniffing and getting nada, you’re set.
