My Mom Never Refrigerates Eggs — Is That Actually Safe?

In most of Europe and North Africa, eggs sit on the counter and nobody thinks twice. In the US, they’re refrigerated by law. The difference isn’t the egg — it’s how it’s washed.

Why washed eggs need the fridge and unwashed eggs don’t American eggs are power-washed, which strips a natural protective coating and lets bacteria in through the shell, so they need refrigeration. Unwashed eggs, like the ones from most local markets and farms, keep that coating and can safely sit out for two to three weeks.

The one mistake that makes counter-stored eggs risky Once an egg has been refrigerated, don’t put it back on the counter — the temperature swing causes condensation on the shell, which undoes the protection and speeds up spoilage.

Takeaway: if your eggs came from a local farm or souk stall, the counter is fine. If they came from a supermarket cold case, keep them refrigerated.

FAQ How long can unwashed eggs sit out? Up to two to three weeks at room temperature if unwashed and kept cool. Can I refrigerate eggs after leaving them out? Yes, but once refrigerated, keep them refrigerated — don’t go back and forth.
