Knowing how to tell if an egg is fresh or bad can save you from food poisoning and wasted groceries. We’ve broken down 5 simple tests anyone can do at home — plus tips, FAQs, and links to related content to help you become a kitchen pro.
1. The Water Test: Sink or Float?
Place your egg gently in a bowl of cold water. If it sinks and lays flat on its side, it’s fresh and good to use. If it stands upright or floats to the surface, it’s time to toss it.

2. Examine the Shell Closely
Look for cracks, sliminess, or powdery spots on the eggshell. These signs may indicate bacterial contamination or mold growth, meaning the egg is spoiled and unsafe to eat.

3. The Sniff Test: Trust Your Nose
Even before cracking, a bad egg gives off a strong sulfur or rotten odor. If you smell anything off, discard the egg immediately.

5. Check the Expiration Date, But Don’t Rely Solely on It
Eggs often last beyond their expiration date if stored properly, but always combine date-checking with other freshness tests for best results.

Bonus Tip: When in Doubt, Throw It Out
If you’re ever unsure about an egg’s freshness or safety, it’s better to discard it than risk food poisoning.
How long do eggs last in the fridge?
Generally, eggs last 3 to 5 weeks refrigerated after purchase. Always use the water test to double-check freshness.
Can I use eggs past the expiration date?
Yes, if they pass other freshness tests like the water test and show no signs of spoilage.
Why do eggs go bad?
Eggs spoil due to bacterial contamination, cracks in the shell, or improper storage conditions.
