Eggs are a staple in most kitchens, whether you’re making breakfast, baking a cake, or preparing a quick snack. But how do you know if the eggs in your fridge are still fresh? Eating spoiled eggs can lead to food poisoning, so it’s essential to check their freshness before using them. Luckily, there are simple ways to tell if an egg is still good or if it has gone bad.
In this article, we’ll explore three easy and foolproof methods to determine whether your eggs are fresh or spoiled.
1. The Water Test: The Easiest Way to Check Freshness
One of the simplest and most reliable ways to test an egg’s freshness is the water test. This method works because eggshells are porous, allowing air to pass through over time. As an egg ages, more air enters, making it less dense and causing it to float.
How to Do the Water Test:
- Fill a bowl or glass with cold water (deep enough to submerge an egg completely).
- Gently place the egg in the water.
- Observe what happens:
- Fresh Egg – Sinks to the bottom and lays flat on its side.
- Slightly Older Egg – Sinks but stands upright at the bottom. It’s still safe to eat but should be used soon.
- Spoiled Egg – Floats to the top. This means the egg has gone bad and should be discarded immediately.
This test is a quick and effective way to check egg freshness without cracking them open.

2. The Sniff Test: The Most Reliable Indicator
If you suspect an egg might be bad, the sniff test is the most foolproof method. Rotten eggs have a distinct and very unpleasant sulfur-like smell that’s hard to miss.
How to Perform the Sniff Test:
- Crack the egg into a small bowl or dish before using it.
- Smell it immediately.
- Fresh Egg – No noticeable odor or a mild natural egg scent.
- Spoiled Egg – A strong, rotten, sulfur-like smell. If you detect this odor, discard the egg immediately.
Even if an egg passes the water test, always use the sniff test before cooking. Bacteria can develop inside eggs, making them unsafe to eat.
3. The Visual Inspection: Look for Clues Inside and Out
Another effective way to check an egg’s freshness is by inspecting it visually. Both the shell and the inside of the egg can give clues about its condition.
Checking the Shell:
- A fresh egg has a clean, smooth shell without cracks or discoloration.
- If the shell has cracks, slimy residue, or powdery mold, it may be contaminated with bacteria and should not be used.
Checking the Inside:
Once cracked open, examine the egg:
- Egg White – A fresh egg has a thick and firm egg white that doesn’t spread much. A bad egg will have a watery, runny white that spreads quickly.
- Egg Yolk – A fresh yolk is round and sits high in the center. If it appears flat or broken, the egg may be old but still usable.
- Discoloration – If you see pink, green, blue, or black spots, the egg has likely been contaminated by bacteria or mold and should be thrown away.
Visual inspection is a great way to double-check if an egg is fresh before consuming it.
How to Store Eggs to Keep Them Fresh Longer
Proper storage can extend the shelf life of your eggs and keep them fresh for longer. Here are some tips:
- Store eggs in the refrigerator at or below 40°F (4°C). Cold temperatures slow down bacterial growth.
- Keep eggs in their original carton to prevent them from absorbing odors and moisture.
- Place eggs on a middle or lower shelf, not in the fridge door, as temperature fluctuations can cause them to spoil faster.
- Use older eggs first by labeling the carton with the purchase date.

How Long Do Eggs Last?
- Fresh eggs (refrigerated, unwashed) – Can last 3-5 weeks beyond the printed expiration date.
- Hard-boiled eggs (peeled or unpeeled) – Best consumed within one week when stored in the fridge.
- Eggs left at room temperature – Should be used within two hours to avoid bacterial contamination.
Final Thoughts: Always Check Before You Crack!
Eggs are a nutritious and versatile food, but eating a spoiled egg can lead to foodborne illness. The good news is that checking an egg’s freshness is easy with these three simple methods:
- The Water Test – A quick way to see if an egg is fresh or old.
- The Sniff Test – The best way to tell if an egg has gone bad.
- The Visual Inspection – Look at the shell, egg white, and yolk for signs of spoilage.
By following these tips and proper storage techniques, you can enjoy fresh, safe eggs every time. Next time you find an egg sitting in your fridge, put these tricks to the test and ensure you’re cooking with quality ingredients!
