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.

Salmonella Concerns
For most intact, unwashed eggs, the risk of Salmonella entering through the shell is low, thanks to the cuticle. If you’re still worried, cooking methods like boiling offer even more safety. The high heat kills bacteria on the surface, while the egg’s inner membrane keeps boiling water from reaching the inside.

Should You Wash Them?
Whether or not to wash eggs ultimately depends on your comfort and where the eggs come from. Store-bought eggs in many countries are already cleaned and sanitized, while farm-fresh eggs often still have their natural coating.

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.
