Should You Store Eggs in the Fridge or Not? Learn the Safest Way to Keep Them Fresh

Eggs are an essential part of our daily meals. Whether it’s an omelet for breakfast or a cake in the oven, many recipes feel incomplete without them. But a simple question often crosses our minds: Should eggs be kept in the refrigerator or at room temperature?

A study published on ResearchGate examined how different temperatures affect egg quality and bacterial growth. The results showed that eggs stored in the fridge maintain thicker yolks and firmer whites, while those kept at room temperature begin to lose quality over time.

Another study, published by the U.S. National Library of Medicine, found that when eggs are stored at higher temperatures or when chilled eggs are exposed to room air, condensation can form on the shells. This moisture makes it easier for bacteria—like Salmonella—to enter and multiply inside the egg. In the experiment, mice became ill after eating eggs kept at 25°C (77°F), but no illness occurred from eggs stored at 5°C (41°F).

According to the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA), eggs should always be stored at 40°F (4°C) or below to prevent foodborne illnesses.

For everyday use, experts recommend keeping eggs in their original carton—this prevents them from absorbing other food odors and helps you keep track of the expiration date. Avoid storing them in the fridge door, as that area experiences frequent temperature changes.

The Best Ways to Keep Eggs Fresh:

To keep your eggs safe and fresh for longer, follow these simple tips:

Always store eggs in their original carton, away from strong-smelling foods. Keep them in the main compartment of the fridge, not in the door. Maintain your fridge temperature at 40°F (4°C) or lower. Do not wash store-bought eggs before refrigerating—washing removes their natural protective coating.

Use older eggs first to ensure freshness. If eggs have been left at room temperature, use them promptly or refrigerate them soon. Do not leave eggs out for more than two hours (or one hour if it’s hot). For long-term storage, freeze eggs without shells—since liquid expands when frozen, shells can crack.

Bring eggs to room temperature only right before cooking or baking. If an egg smells bad or its yolk or white looks discolored, discard it immediately—spoiled eggs can be dangerous to your health.
