How Long Eggs Stay Fresh in Your Refrigerator

Eggs last three to five weeks in the refrigerator, depending on how you store them

The shelf life of eggs starts the moment they arrive at the store, not when you bring them home. Most eggs you buy are already one to two weeks old. That means a carton marked with a "sell by" date of March 15 will stay safe to eat until around late April, assuming your refrigerator stays at 40°F or below. The exact window depends on storage method and how cold your fridge actually runs.

Eggs are remarkably durable because the shell is a natural barrier against bacteria. The real risk comes from temperature swings—moving eggs in and out of the cold, or storing them in a warm spot. A refrigerator that holds steady at 40°F gives you the full window. One that creeps toward 45°F cuts it shorter.

You can tell if an egg is still good by cracking it into a bowl before cooking. A fresh egg has a firm, centered yolk and thick, clear whites. An older egg (but still safe) has a flatter yolk and thinner whites. If the yolk breaks easily or the white is cloudy or discolored, discard it.

Key Takeaways

• Eggs stored in the coldest part of your refrigerator (usually the back of a shelf, not the door) last three to five weeks from the day you bring them home.
• The door of your refrigerator is warmer than the shelves, so eggs stored there spoil faster—keep them on a middle or lower shelf instead.
• A steady temperature of 40°F or below is essential; eggs stored in a fridge that fluctuates above 45°F will spoil within two to three weeks.
• You can safely eat an egg past its printed date if it passes the float test (sinks in water) or the crack test (firm yolk, clear whites).

Why the refrigerator door is the worst place for eggs

The door is the warmest part of your refrigerator. Every time you open it, warm air rushes in and the temperature spikes. Eggs are sensitive to these swings. Storing them on a door shelf means they experience temperature changes multiple times a day, which speeds up the aging process and can allow bacteria to multiply if the temperature climbs above 45°F for too long.

Move eggs to a middle or lower shelf instead, where the temperature stays most stable. If your refrigerator has a dedicated egg compartment on the door (many do), ignore it for long-term storage. Use it only if you plan to eat those eggs within a week or two.

How to check if an egg is still safe to eat

The printed date on the carton is a "sell by" or "pack date," not an expiration date. Eggs are safe well past that date if stored correctly. The most reliable test is the float test: fill a bowl with cold water and gently place the egg in it. A fresh egg sinks and lies flat on the bottom. An older egg stands upright or floats because the air cell inside has grown larger. A floating egg is still safe to eat, but use it soon.

If you crack the egg open, look at the yolk and whites. A fresh egg has a firm, domed yolk that stays centered and thick, clear whites. As an egg ages, the yolk flattens and the whites become thinner and more watery. This is normal and safe. Discard the egg only if the yolk breaks easily, the white is cloudy or discolored, or there is any off smell.

Never rely on smell alone. Some spoiled eggs smell bad, but not all do. The float test and crack test are more reliable.

Temperature matters more than you think

A refrigerator set to 40°F is the standard safe temperature for eggs. If your fridge runs warmer—say, 45°F or above—eggs will spoil faster, sometimes within two to three weeks. If it runs colder, closer to 35°F, eggs can last closer to five weeks or even slightly longer.

Check your refrigerator temperature with a simple thermometer (they cost a few dollars and sit on a shelf). Place it in the middle of the fridge, away from the back wall and the door, and leave it for a few hours. If the reading is above 40°F, adjust the dial toward colder. If it is below 35°F, adjust it warmer—too cold can cause other foods to freeze.

Temperature consistency matters as much as the number itself. A fridge that swings between 35°F and 45°F will age eggs faster than one that holds steady at 40°F, even though the average is the same.

Storing eggs in their original carton keeps them fresher longer

The cardboard carton does more than protect eggs from breaking. It reduces moisture loss and shields eggs from odors in the refrigerator. Eggs are porous and absorb smells from strong foods like onions, fish, and garlic. The carton acts as a barrier.

Keep eggs in the carton they came in. If you transfer them to a plastic holder or the door compartment, you lose this protection and they age faster. The carton also has the pack date printed on it, so you know how old they are.

Raw eggs versus cooked eggs: different timelines

Raw eggs in the shell last three to five weeks. Hard-boiled eggs, once peeled or unpeeled, last about one week in the refrigerator. The cooking process breaks down the protective shell and exposes the egg to bacteria. Store hard-boiled eggs in an airtight container on a shelf (not the door) and use them within seven days.

Scrambled eggs, fried eggs, and egg dishes last three to four days. Store them in an airtight container and reheat gently before eating. If you are unsure how long a cooked egg dish has been in the fridge, use the smell and appearance test—if it looks or smells off, discard it.

What to do if you have more eggs than you can use

If you buy eggs in bulk or your flock is productive, freezing is a reliable option. Crack eggs into a bowl, beat them lightly, and pour them into ice cube trays or freezer containers. Frozen eggs last up to four months. Thaw them in the refrigerator overnight before cooking. Label the container with the date so you know how long they have been frozen.

You can also freeze just the whites or just the yolks, though yolks need a small addition of salt or sugar to prevent them from becoming grainy. Whites freeze as-is. This method works well if you have recipes that use only one part of the egg.

Frequently Asked Questions

Can I eat an egg that floats in water?

Yes. A floating egg has a larger air cell, which means it is older, but it is still safe to eat if it sinks partway or floats. Cook it thoroughly and use it soon. If the egg floats high and bobs at the surface, it is very old—still safe, but the texture and flavor will be noticeably different.

How do I know if an egg went bad without cracking it open?

The float test is your best bet. A fresh egg sinks; an older egg stands upright or floats. You can also hold the egg up to a bright light and look through it—a fresh egg has a small air cell at the wide end, while an older egg has a larger one. If you crack it and it smells sulfurous or sour, discard it.

Do I need to wash eggs before storing them?

No. Store-bought eggs are already washed and sanitized. Washing them at home removes the protective coating and can allow bacteria to enter through the pores. If you have backyard chickens, wash eggs only right before cooking, not before storage.

Will eggs freeze if I leave them in the back of my refrigerator?

Unlikely, unless your fridge is set dangerously cold (below 32°F). A properly functioning refrigerator at 40°F will not freeze eggs. If eggs are freezing, your fridge is too cold and you should adjust the temperature dial upward to prevent other foods from freezing as well.

Can I store eggs on the counter at room temperature?

Not safely in the United States. Eggs sold in the U.S. are washed, which removes the protective coating and makes them more vulnerable to bacteria. They must be refrigerated. In some other countries, unwashed eggs with the protective coating intact can be stored at room temperature, but this does not apply to American store-bought eggs.
