Eggs are a kitchen staple, but a simple question sparks debate: should you wash them before cooking? Surprisingly, the answer isn’t as simple as it seems.
Why People Wash Eggs
Some people wash eggs out of habit. Others do it to ensure cleanliness. But eggs naturally come with a built-in defense called the cuticle or egg bloom. Think of it as the egg’s armor against bacteria.
The Egg’s Natural Shield
The cuticle is a thin layer that seals the pores of the shell. It prevents bacteria from entering and reduces moisture loss. In other words, washing eggs removes this protective barrier, leaving the egg more vulnerable.
What About Salmonella?
Salmonella is the notorious worry when handling eggs. Fortunately, intact, unwashed eggs carry a minimal risk. The cuticle blocks bacteria from penetrating the shell.
Still worried? Boiling eggs offers extra protection. High temperatures kill bacteria on the surface without compromising the egg inside. And thanks to the inner membrane, boiling water won’t seep through the shell’s pores.
