How Long Store-Bought Eggs Last in Your Refrigerator

Store-bought eggs stay fresh for three to five weeks from the day you bring them home, depending on how you store them and whether the carton has been opened.

The shelf life printed on the carton—usually labeled "Sell By" or "Expiration Date"—is not the same as how long the eggs will actually last in your refrigerator. That date tells the store when to stop selling them, not when they spoil. Eggs are remarkably durable because the shell and the protective membrane inside create a barrier against bacteria. What matters most is keeping them cold and undisturbed.

The three-to-five-week window assumes you store eggs in their original carton on a shelf inside the refrigerator (not the door), where the temperature stays between 35°F and 40°F. The carton itself protects the eggs from absorbing odors and flavors from other foods, and it prevents them from rolling around and cracking. Once you crack an egg or remove it from the carton, the clock moves much faster.

Key Takeaways

• Store-bought eggs in their original carton last three to five weeks in the refrigerator, well past the printed "Sell By" date.
• Keep eggs on a refrigerator shelf, not in the door, because door temperatures fluctuate and shorten shelf life.
• A raw egg white lasts about four days in the refrigerator once separated, while a raw yolk lasts three to four days in a covered container.
• Cooked eggs—hard-boiled, scrambled, or baked into dishes—last three to four days when stored in an airtight container.
• You can freeze raw eggs for up to one year if you crack them into a container first; do not freeze them in the shell.

Why the Printed Date Is Not the Real Expiration

The "Sell By" date on an egg carton is set by the producer and tells retailers when to remove the eggs from the shelf. In the United States, this date is typically 30 days after the eggs were packed. Once you take the eggs home and refrigerate them, they remain safe to eat for another week or two beyond that date, sometimes longer.

The USDA states that raw eggs in the shell are safe to use for three to five weeks after purchase. This is because the shell and the inner membrane protect the contents from contamination. The eggs do not spoil suddenly on the printed date; they gradually lose quality—the yolk becomes flatter, the white becomes thinner—but they remain safe to cook with and eat.

The Right Place to Store Eggs in Your Refrigerator

Store eggs on a shelf inside the main body of the refrigerator, not in the door. The door is the warmest part of the refrigerator because it is opened and closed repeatedly, and the temperature there can swing by 10 to 15 degrees each time. Eggs need consistent cold to last their full shelf life.

Keep them in their original carton. The carton serves three purposes: it insulates the eggs against temperature swings, it prevents them from absorbing odors from fish, onions, or other pungent foods, and it protects them from cracking if something shifts on the shelf. If you have transferred eggs to a bowl or container, move them back to the carton as soon as you can.

How to Tell If an Egg Has Gone Bad

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 its side. An older egg stands upright or floats because the air cell inside has expanded over time. A floating egg is not necessarily bad—it depends on how much it floats—but it signals that the egg is nearing the end of its life and should be used soon.

When you crack an egg, trust your senses. A bad egg smells distinctly sulfurous or off; the yolk may be discolored or the white may be cloudy or pink. If you are unsure, do not use it. A fresh egg has a clear white, a firm yolk, and no odor. If the egg has been stored properly and is within the three-to-five-week window, it is almost certainly fine.

Raw Egg Whites and Yolks Separated and Stored

If you have separated eggs and stored the whites and yolks separately, they last much shorter than whole eggs. A raw egg white in a covered container lasts about four days in the refrigerator. A raw yolk lasts three to four days, but it must be covered with a thin layer of cold water or oil to prevent the surface from drying out and forming a skin.

Store separated whites and yolks in small, airtight containers or covered bowls. Label them with the date so you know when you separated them. If you are not sure how long they have been sitting, err on the side of caution and discard them. Separated eggs are more exposed to bacteria than whole eggs because the protective shell is gone.

Cooked Eggs and Egg Dishes

Hard-boiled eggs last three to four days in the refrigerator when stored in their shells or peeled and placed in an airtight container. Scrambled eggs, fried eggs, and baked egg dishes like frittata or quiche also last three to four days. Store them in shallow, airtight containers so they cool quickly and stay moist.

Egg-based dishes that contain mayonnaise, cream, or other perishable ingredients—like egg salad or deviled eggs—should be eaten within three days. If the dish sits at room temperature for more than two hours (or one hour if the room is above 90°F), discard it rather than refrigerate it, because bacteria may have already begun to multiply.

Freezing Eggs for Long-Term Storage

You can freeze raw eggs for up to one year, which is useful if you have more eggs than you can use before they age. Never freeze eggs in the shell; the contents expand as they freeze and crack the shell. Instead, crack the eggs into a bowl, beat them gently to combine the white and yolk, and pour them into a freezer-safe container or ice cube tray.

If you freeze whole beaten eggs, label the container with the number of eggs and the date. Thaw them in the refrigerator overnight before using them in cooked dishes like scrambled eggs, baked goods, or omelets. Frozen eggs work well in recipes where they will be heated but are not ideal for dishes where you want a runny yolk or a fluffy white.

Frequently Asked Questions

Can I eat an egg that floats in the water test?

A floating egg is old but not necessarily unsafe. If it floats high and bobs at the surface, use it soon or discard it. If it sinks but stands upright, it is still good for cooking. Crack it into a bowl first to check for odor or discoloration before adding it to your recipe.

Do brown eggs last longer than white eggs?

No. Shell color does not affect shelf life. Brown and white eggs last the same amount of time when stored the same way. The difference is only in the breed of hen that laid them and the thickness of the shell, which varies by individual egg, not by color.

What if I left eggs on the counter for a few hours?

Eggs left at room temperature for less than two hours are still safe to refrigerate and use normally. If they sat out for more than two hours, or if the room was very warm, discard them. Bacteria multiply fastest in the danger zone between 40°F and 140°F.

Can I store eggs in a plastic container instead of the carton?

You can, but the original carton is better because it provides insulation and prevents the eggs from rolling and cracking. If you use a plastic container, make sure it has a tight-fitting lid and keep it on a refrigerator shelf, not the door.

How long do farm-fresh or backyard eggs last?

Farm-fresh eggs without a protective coating last about three to four weeks in the refrigerator, slightly shorter than store-bought eggs. Store-bought eggs are often washed, which removes the natural protective bloom, but they are also graded and handled under strict conditions. Backyard eggs may have dirt or bacteria on the shell, so wash them gently before storing.
