You can tell if an egg is bad by using several simple tests: 1. The Float Test

• Fill a bowl with cold water and gently place the egg in it.
• If the egg sinks and lies flat on its side, it is very fresh.
• If it sinks but stands upright or tilts, it is older but still safe to eat.
• If the egg floats, it is too old and should be discarded.
  This works because as eggs age, air enters through the porous shell, enlarging the air pocket and making the egg buoyant

2. The Sniff Test

• Smell the egg, either through the shell or after cracking it open.
• A bad egg emits a strong sulfur or rotten smell. If you detect this odor, discard the egg immediately

3. Visual and Texture Inspection After Cracking

• Crack the egg onto a flat surface.
• Fresh eggs have a thick, slightly opaque white that doesn’t spread much and a rounded, plump yolk.
• Older eggs have a watery, runny white and a flatter yolk.
• If the white or yolk shows discoloration (pink, iridescent hues) or any unusual appearance, the egg is bad and should be thrown out

4. Shake Test

• Hold the egg close to your ear and shake gently.
• If you hear a sloshing sound, the yolk is likely watery and the egg is old or bad

Additional Tips

• Check the egg’s shell for cracks, sliminess, or powdery coatings, which can indicate contamination

• Always wash your hands and surfaces after handling eggs to avoid bacteria like salmonella

Using these methods together will help you confidently determine if an egg is fresh or bad before use.
