How to Test if an Egg is Fresh
There are a few simple ways to test the freshness of an egg, you can do these tests right after collecting eggs or before you use them:
Float Test:
- Place your egg in a bowl of cold water.
- If the egg sinks to the bottom and lies horizontally, it’s very fresh and safe to eat.
- If the egg floats a bit or stands vertically, it’s past its peak freshness but is still edible.
- If the egg floats to the surface, the egg is old and should be thrown out.
Visual Inspection:
- Check for any cracks or powdery mold on the shell – Discard the egg if it’s cracked or moldy.
- Crack the egg open – Fresh eggs have thick, firm egg whites, plump, round yolks, and very little spreading. Old eggs will have flat yolks and watery egg whites and may not be safe to consume.
- If the shell is thin or brittle, it means that egg didn’t get enough calcium while being formed. Since these shells are weak, they are easily contaminated and shouldn’t be eaten.
Smell Test: Fresh eggs should have little to no smell when cracked open. Old eggs may have a strong, sulfurous odor. If your egg smells rotten, throw it out.
It’s essential to understand the importance of taking the proper precautions when handling and storing eggs to prevent foodborne sickness. A good rule of thumb when testing an egg to determine freshness is “When in doubt, throw it out.”
