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.
Washing or Not: It’s Your Choice
Ultimately, washing eggs depends on your comfort and their source. If you buy eggs from a trusted supplier and practice safe handling, you can leave them unwashed.
Respect the Humble Egg
Whether you wash them or not, eggs deserve respect. Their natural armor keeps them safe, and their versatility makes them essential in the kitchen. Next time you cook an omelet or deviled eggs, remember the humble egg and its cuticle.
