Eggs are a kitchen staple, but many people wonder whether they should be washed before use. The answer depends on understanding how eggs naturally protect themselves.
The Egg’s Natural Shield
Fresh eggs come with a thin layer called the cuticle, or “bloom.” This natural coating seals tiny pores in the shell and acts as the egg’s built-in armor, keeping bacteria out and preventing moisture loss. When eggs are washed, this protective layer is removed, leaving the shell more exposed to bacteria such as Salmonella.

If the eggs come from a trusted source and you handle them properly, leaving them unwashed is usually safe. Eggs may seem simple, but their natural design offers impressive protection. Whether you rinse them or not, understanding the cuticle helps you handle your eggs with confidence.
