How Long Fresh Chicken Eggs Last in the Refrigerator

Fresh chicken eggs stay safe to eat for three to five weeks from the day you bring them home, as long as you store them in the coldest part of your refrigerator—usually the back of a shelf, not the door.

The shell itself is a barrier, but it's porous. Cold slows the growth of bacteria inside the egg and slows moisture loss through the shell. Room temperature does both much faster. A refrigerator set to 40°F (4°C) or below is what you need; warmer than that and the timeline shrinks.

The date on the carton—if there is one—tells you when the eggs were packed, not when they expire. Eggs can be sold for up to 30 days after packing in most places, so that date is a starting point, not an end point. What matters more is how you store them from the moment they arrive at your house.

Key Takeaways

• Store eggs in the coldest part of your refrigerator (back of a shelf, not the door) to reach the full three- to five-week window.
• Keep eggs in their original carton, which protects them from absorbing odors and flavors from other foods and slows moisture loss.
• A refrigerator temperature of 40°F (4°C) or below is required; warmer temperatures cut the safe storage time in half.
• You can test an older egg by placing it in a bowl of water—if it sinks and lies flat, it's fresh; if it stands upright or floats, it's past its prime.
• Cooked eggs (hard-boiled, scrambled, baked into dishes) last three to four days in the refrigerator, separate from raw eggs.

Why the Refrigerator Door Is the Wrong Place

The door is the warmest part of your refrigerator because it opens and closes constantly, letting warm air in. Eggs stored there may only last two to three weeks instead of five. If you have limited shelf space, move something else to the door and give the eggs a spot on a back shelf where the temperature stays steady.

The original carton matters too. It insulates the eggs and keeps them from rolling around, which can crack the shell and expose the contents to bacteria. It also prevents eggs from absorbing odors from fish, onions, or other pungent foods in your fridge. If your carton is damaged, transfer the eggs to a clean container with a lid or cover, but the carton is ideal.

How to Tell If an Egg Is Still Good

The water test is the most reliable way to check an egg you're unsure about. Fill a bowl with cold water and gently place the egg in it. A fresh egg sinks to the bottom and lies on its side. An older egg stands upright on the bottom or bobs near the surface. A very old egg floats. This happens because the air cell inside the egg grows larger as moisture evaporates through the shell over time.

You can also crack the egg into a small bowl and look at it. A fresh yolk is round and firm, and the white clings tightly around it. An older yolk flattens and spreads, and the white becomes thin and watery. If you see any discoloration, smell anything off, or notice the yolk or white has an unusual texture, throw it out.

The smell test works too, though it's less precise. A fresh egg has almost no smell when you crack it. An old egg may smell sulfurous or sour. Trust your nose—if something seems wrong, it probably is.

Raw Eggs Versus Cooked Eggs: Different Timelines

Raw eggs in the shell last three to five weeks. Raw eggs that have been cracked and beaten (for scrambling or baking) last only one to two days in a sealed container. Once you cook an egg—whether you boil it, scramble it, or bake it into a dish—the timeline changes again.

Hard-boiled eggs last three to four days in the refrigerator. Scrambled eggs, fried eggs, and eggs baked into casseroles or quiches also last three to four days. Store them in an airtight container or cover them tightly with plastic wrap or foil to prevent them from drying out and absorbing odors. Label the container with the date you cooked them so you don't lose track.

Temperature and Humidity Matter More Than You Think

A refrigerator that runs warmer than 40°F (4°C) cuts egg storage time significantly. If your fridge tends to be warmer—which can happen if it's overstuffed, if the door seal is loose, or if it's an older model—eggs may only last two to three weeks. Check your refrigerator's temperature with a simple thermometer (they cost a few dollars at any grocery store). If it's running warmer than 40°F, adjust the dial and recheck after a few hours.

Humidity also plays a role. A very dry refrigerator causes eggs to lose moisture faster through the shell. If your fridge seems dry, keeping eggs in their carton (rather than loose in a container) helps slow that loss. Some refrigerators have a humidity drawer; eggs don't need it, but they do fine in a normal shelf.

What Happens If You Leave Eggs Out

Eggs left at room temperature for more than two hours begin to develop bacteria inside the shell at a faster rate. After two hours, the risk rises. In warm kitchens (above 70°F), that window shrinks to one hour. If eggs have been left out longer than that, cook them thoroughly (yolk and white both fully set) before eating, or discard them.

This is why farmers markets and some grocery stores keep eggs at room temperature—in those settings, the eggs are fresher and have been out for a shorter time. Once you bring them home, refrigerate them right away. Don't leave them on the counter while you unpack groceries.

Freezing Eggs for Longer Storage

If you have more eggs than you can use in five weeks, you can freeze them. Crack the eggs into a bowl, beat them lightly, and pour them into ice cube trays or a freezer container. Label the container with the date and the number of eggs. Frozen eggs last up to four months.

You can also freeze raw egg whites or yolks separately if a recipe calls for one or the other. Thaw frozen eggs in the refrigerator overnight before using them. Use thawed eggs only in cooked dishes (scrambled eggs, baked goods, quiches), not in recipes that call for raw eggs, because freezing and thawing can affect the texture and structure of the egg.

Frequently Asked Questions

Can I eat an egg that floats in water?

A floating egg is old but not necessarily unsafe if the shell is intact and uncracked. Cook it thoroughly—both yolk and white fully set—before eating. If the shell is cracked or the egg smells off, discard it. When in doubt, throw it out.

Do eggs need to be washed before I store them?

No. Washing removes the protective coating on the shell and can actually allow bacteria to enter. Store eggs as they come, unwashed, in their carton. If there's visible dirt, you can wipe it gently with a dry cloth, but don't rinse them.

Why do some eggs have a blood spot inside?

A blood spot is a small amount of blood from the hen's reproductive system. It's harmless and doesn't mean the egg is unsafe. You can eat it or remove it with the tip of a knife. It doesn't affect storage time.

Are brown eggs fresher than white eggs?

No. Shell color depends on the breed of hen and has nothing to do with freshness, nutrition, or how long the egg lasts. Brown and white eggs store the same way and last the same amount of time.

What if my refrigerator doesn't have a back shelf?

Store eggs on the lowest shelf available, away from the door. The lower the shelf, the colder and more stable the temperature. If your fridge has only door storage, move eggs to a shelf as soon as you get home, or consider a small shelf organizer that creates a cooler zone.
