Why You Shouldn’t Store Eggs in the Fridge — And When You Should

Eggs last longer at room temperature in Europe because their natural protective layer remains intact, unlike in countries where eggs are washed and must be refrigerated.

For many households, storing eggs in the refrigerator feels like second nature. Built‑in egg trays in fridge doors even seem to encourage it. But in much of Europe, including Austria and Germany, experts recommend keeping eggs at room temperature — at least for the first couple of weeks after purchase. Here’s why.

Why Refrigeration Isn’t Necessary in Europe

In the United States and Canada, eggs are washed and sanitized before reaching supermarket shelves. This process removes dirt and bacteria but also strips away the egg’s natural protective cuticle, making the shell more permeable to germs. As a result, eggs there must be kept refrigerated to prevent contamination.

In Europe, however, industrial washing is prohibited. The cuticle remains intact, providing a natural barrier against bacteria such as Salmonella. Additionally, hens are routinely vaccinated against Salmonella, further reducing risk. Because of these safeguards, eggs can safely be stored at room temperature without compromising food safety.

When You Should Move Eggs to the Fridge

After about 18–20 days, the egg’s natural protective layer begins to weaken. At this point, refrigeration helps extend freshness and reduce bacterial risk. Once eggs are chilled, however, the cold chain must remain unbroken. Moving cold eggs back to room temperature causes condensation, which can allow bacteria to penetrate the shell.

How to Store Eggs Properly in the Fridge

If you decide to refrigerate your eggs, food‑safety experts recommend the following:

1. Avoid the fridge door

Temperature fluctuations from frequent opening make the door the worst place for eggs. Store them farther back in the fridge, where temperatures remain stable — ideally at 7°C or below.

2. Keep them away from strong odors

Eggshells are porous and easily absorb smells from nearby foods. Storing them away from pungent items helps preserve flavor.

3. Maintain distance from other foods

Direct contact with other items can transfer bacteria to the shell. Keeping eggs in their original carton provides protection and helps prevent cross‑contamination.

Bottom Line

Room temperature is fine for European eggs during the first couple of weeks.
Refrigerate after 18–20 days to extend shelf life.
Never break the cold chain once eggs have been chilled.
Store them in the main fridge compartment, in their carton, away from strong odors and other foods.
