How Long Fresh Eggs Stay Good in Your Refrigerator

Fresh eggs last three to five weeks in the refrigerator when stored properly

The shelf life of fresh eggs depends on how they were handled before you bought them and how you store them now. Eggs purchased from a grocery store in the United States are already several days old by the time you bring them home—they were laid, collected, washed, graded, and shipped before reaching the shelf. From that point, you have roughly three to five weeks to use them, assuming your refrigerator stays at 40°F or below and you keep the eggs in their original carton.

The key is that eggs age slowly in cold storage. The shell is porous, and the protective cuticle (a natural coating) helps seal moisture in and bacteria out. Keeping eggs cold slows the natural aging process inside the shell, which is why refrigeration extends their life so dramatically compared to leaving them on the counter.

If you bought farm-fresh eggs directly from a farmer or collected them yourself, the timeline shifts. Unwashed farm eggs can last four to five weeks in the refrigerator because the bloom (natural protective coating) is still intact. Washed farm eggs behave more like store-bought eggs and last about three to five weeks.

Key Takeaways

• Store eggs in their original carton on a shelf (not the door) where the temperature stays steady at 40°F or below.
• Store-bought eggs last three to five weeks from the day you bring them home; farm-fresh unwashed eggs last four to five weeks.
• The carton protects eggs from absorbing odors and flavors from other foods and prevents moisture loss.
• A floating egg in water does not automatically mean it is bad—age alone does not determine safety, but a foul smell or pink discoloration does.

Why the carton matters more than you think

The cardboard carton is not just packaging—it is essential storage. Eggs are porous, and they absorb odors and flavors from everything around them. A carton creates a barrier between the eggs and strong-smelling foods like fish, onions, or aged cheese. It also slows water loss from inside the shell, which keeps the egg fresher longer.

Never transfer eggs to a decorative bowl or basket, even if it looks nicer in your kitchen. The exposed shell will absorb odors, dry out faster, and the eggs will age more quickly. Keep them in the original carton, and store that carton on a middle or lower shelf where the temperature is most stable. The refrigerator door is warmer and experiences temperature swings every time you open it, so eggs stored there age faster.

How to tell if an egg is still safe to eat

The most reliable test is smell. Crack the egg into a bowl or cup before cooking. A fresh or aging egg has no odor or a very faint smell. A spoiled egg smells distinctly sulfurous or rotten—you will know immediately. If you smell nothing unusual, the egg is safe to cook and eat.

Visual signs matter too. Look at the yolk and white after cracking. A fresh egg has a firm white and a yolk that sits high and round. As an egg ages, the white becomes thinner and more watery, and the yolk flattens slightly. This is normal aging, not spoilage, and the egg is still safe. However, if you see pink, iridescent, or greenish discoloration in the white or yolk, discard the egg—these colors indicate bacterial growth.

The float test (placing an egg in water to see if it sinks or floats) tells you the egg's age but not whether it is safe. An older egg floats because the air cell inside has expanded as moisture evaporates through the shell. A floating egg may still be perfectly good to eat if it smells and looks normal. Use smell and appearance as your safety guides, not the float test alone.

Storage temperature and consistency matter

Eggs are sensitive to temperature swings. A refrigerator that holds a steady 40°F will keep eggs fresh longer than one that fluctuates between 35°F and 45°F. Check your refrigerator's temperature with an inexpensive thermometer if you are unsure. Most refrigerators have a dial or digital control—adjust it so the coldest part (usually the back of the lower shelf) stays around 37°F to 40°F.

Avoid storing eggs in the door, where temperatures rise and fall with every opening. The door is typically 5 to 10 degrees warmer than the main compartment. If your refrigerator is very full or you have limited shelf space, the door is a compromise, but a shelf is always better. Consistency matters more than hitting an exact temperature—a steady 42°F is better than a fluctuating 38°F to 45°F.

What happens as eggs age in storage

An egg does not spoil suddenly. It ages gradually, and you can use eggs at different stages depending on what you are cooking. A very fresh egg (less than one week old) has a firm white that holds together when you fry it—ideal for frying or poaching. A slightly older egg (two to three weeks) has a thinner white that spreads more when you fry it, but it is perfect for scrambling, baking, or hard-boiling.

Hard-boiling is actually easier with older eggs. Eggs that are two to three weeks old peel more cleanly than very fresh eggs because the membrane between the shell and white has begun to separate. If you are planning to hard-boil eggs, buy them a week or two before you need them, or use eggs near the end of their storage window.

An egg that is four to five weeks old may have a noticeably thinner white and a flatter yolk, but if it smells and looks normal, it is still safe to cook. Use these older eggs for baking, scrambling, or making custards where the texture of the white does not matter as much.

Storing cooked eggs and egg dishes

Hard-boiled eggs last about one week in the refrigerator in their shell. Peel them and store them in an airtight container, and they last three to four days. Keep them away from strong-smelling foods because the cooked white is more porous than the raw shell.

Scrambled eggs, omelets, and egg-based casseroles last three to four days in an airtight container. Store them on a shelf, not the door. Egg salad and mayonnaise-based egg dishes last three to four days as well, but the mayonnaise can mask early signs of spoilage, so use them sooner rather than later if you are uncertain.

Leftover egg dishes should be cooled to room temperature before refrigerating, but do not leave them sitting out for more than two hours. If your kitchen is warm (above 90°F), refrigerate within one hour.

Frequently Asked Questions

Can I freeze raw eggs to make them last longer?

Yes. Crack eggs into an ice cube tray, freeze them, then transfer the cubes to a freezer bag. Raw eggs last three to four months frozen. Thaw them in the refrigerator before cooking. Do not freeze eggs in the shell—the contents expand and crack the shell.

Why do some eggs have a date printed on the carton?

The "sell by" or "best by" date on the carton is a guideline for retailers, not a hard expiration. Eggs are usually good for three to five weeks after that date if stored properly. The date helps stores rotate stock, but it is not a safety cliff.

Is it safe to eat an egg with a cracked shell?

A small hairline crack is usually fine if the egg has been refrigerated the whole time. A large crack or one where the membrane is exposed increases the risk of bacterial entry. When in doubt, discard it. If you crack an egg and see bacteria-related discoloration, do not use it.

Do brown eggs last longer than white eggs?

No. Shell color does not affect shelf life. Brown and white eggs age at the same rate. The difference is only the breed of hen that laid it and the pigment in the shell.

What should I do if I find an egg I forgot about in the back of the fridge?

Check the smell first. If it smells normal, crack it into a bowl and look at the color and consistency. If both look normal, it is safe to cook. If you cannot remember how long it has been there and it is past five weeks, discard it to be safe.
