Should You Wash Eggs Before Cooking?

Eggs are a kitchen staple, but a simple question sparks debate: should you wash them before cooking? Surprisingly, the answer isn’t as clear-cut as many think.

Why People Wash Eggs

Some wash eggs out of habit. Others do it to feel like they’re being extra safe. But here’s the catch: eggs come with a natural shield called the cuticle or egg bloom. Think of it as the egg’s built-in armor against bacteria.

The cuticle is a thin protective layer that seals the eggshell’s pores. It blocks bacteria and slows moisture loss. In other words, the egg says, “I’ve got this!” Washing an egg removes this defense, making the egg more vulnerable.

What About Salmonella?

Salmonella often worries egg lovers, but here’s the good news: the risk is low for intact, unwashed eggs. The cuticle acts as a natural barrier, preventing bacteria from penetrating the shell.

Still cautious? Boiling eggs is a reliable safety measure. The high heat cooks the egg and kills bacteria on the shell. And don’t worry about water seeping inside—the egg’s inner membrane provides another layer of protection.

When to Wash (and When to Skip It)

Ultimately, whether you wash eggs depends on your comfort level and their source. Eggs from a trusted farm or grocery store, handled properly, are safe to cook without washing.

If you do wash eggs, make sure to use warm water and dry them immediately to avoid compromising the cuticle. But for many, leaving the eggs unwashed is actually the safest approach.

Appreciate the Humble Egg

Eggs are remarkable. Their natural armor keeps them safe and fresh. The next time you cook an omelet, poach, or make deviled eggs, remember the protective cuticle and the ingenious design of this kitchen classic.
