Why Is It Important to Check Eggs?
Eating bad eggs can cause stomach pain. You may get diarrhea or a fever. This is because bad eggs have bacteria. These bacteria can harm your body. So, checking eggs before cooking is very important. It keeps you and your family safe and healthy.

How to Tell If an Egg Has Gone Bad
There are many ways to check eggs. You can use your eyes, nose, and even water. Here are the best ways to know if an egg is fresh or bad.
1. Check The Egg’s Shell
Look at the egg shell carefully.
- Cracks or Slimy Shell: If the shell has cracks, do not use the egg. Bacteria can enter. If it feels slimy or powdery, it may be bad.
- Color: Eggs can have different colors. Brown or white is normal. But if you see strange spots or colors on the shell, it might be spoiled.
2. The Float Test
This test uses water. It is easy and works well.
- Fill a bowl with cold water.
- Gently put the egg in the water.
- Watch what happens:
| Egg’s Position in Water | What It Means |
|---|---|
| Sinks and lays flat on the side | Egg is fresh and good to eat. |
| Sinks but stands upright | Egg is old but still okay to eat. |
| Floats to the top | Egg has gone bad. Do not eat. |
Why does this work? Eggs have a small air pocket inside. As eggs age, this pocket gets bigger. Bigger air pocket makes the egg float.
