Why Do Eggs Go Bad?

Eggs are a perishable food item, which means that they can spoil quickly if not stored or handled correctly. The main reason for eggs going bad is because of bacteria. Fresh eggs have a protective coating called a cuticle that helps keep bacteria from entering the egg. However, this coating can be removed during washing or handling, which can allow harmful bacteria to enter the egg and grow.

Another reason for eggs going bad is because of air. Eggs have an air sac at the round end of the egg that expands as the egg ages. As the air sac gets larger, the egg white becomes thinner, and the yolk becomes flatter. This can make the egg more prone to breaking and can allow bacteria to enter the egg more easily.

How Can You Tell If An Egg Has Gone Bad?

It can be difficult to tell if an egg has gone bad just by looking at it. However, here are some signs that an egg may be bad:

  • The egg white is runny or watery
  • The egg yolk is flat and not rounded
  • The egg has a foul odor
  • The eggshell is cracked or dirty

If you are unsure if an egg is bad, you can do the float test. Fill a bowl with water and gently place the egg in the water. If the egg sinks to the bottom and lays flat on its side, it is fresh. If the egg stands upright or floats to the top, it is old and should be discarded.
