Fresh eggs last anywhere from 3 to 5 weeks in the refrigerator when kept at optimal temperatures. You don't need to guess whether your eggs are still good to eat. Simple kitchen tests and correct storage habits take the mystery out of egg safety.
Understanding the actual timeline helps you reduce food waste while keeping your household safe. While grocery cartons print specific dates, these guidelines tell you how long your eggs remain fresh after you bring them home from the store.
How Long Eggs Last in the Fridge
Raw whole eggs in their shells remain safe and fresh for 3 to 5 weeks from the date you place them in your refrigerator. The expiration date on the carton often passes while the eggs are still completely fine to consume.
Different states of eggs have vastly different refrigerator lifespans:
- Raw whole eggs in shell: 3 to 5 weeks.
- Raw egg whites and yolks (separated): 2 to 4 days stored in covered containers.
- Hard-boiled eggs (in shell or peeled): 1 week.
- Liquid egg substitutes (opened): 3 to 4 days.
- Cooked egg dishes (quiches, casseroles): 3 to 4 days.
Keeping your refrigerator at or below 40 degrees Fahrenheit (4 degrees Celsius) plays the most important role in hitting that 5-week mark.
Best Storage Practices for Maximum Freshness
Where and how you store your eggs matters. Many refrigerators feature built-in egg trays on the door, but this spot experiences the most temperature fluctuation every time you open the fridge.
Instead, keep your eggs on an interior shelf where the temperature stays stable. Leave the eggs inside their original cardboard carton. Cardboard protects the shells from cracking, absorbs excess moisture, and shields the porous shells from absorbing strong food odors from leftovers.
Position the carton toward the back of the shelf rather than near the front or the door. If you want to maximize freshness, keep the pointed end of the egg facing down. This keeps the air cell at the top, positioning the yolk in the center and away from air pockets.
How to Tell If an Egg Has Gone Bad
You don't need to throw away an egg just because the date on the carton passed yesterday. Instead, rely on sensory checks to verify freshness.
The Smell Test
Cracking the egg into a small bowl provides the easiest and most reliable check. Fresh eggs have a neutral or mild scent. If you catch a sulfurous, rotten, or gassy odor, discard the egg immediately.
The Float Test
Place an egg in a glass of cold water.
- Sinks to the bottom flat: The egg is very fresh.
- Stands on one end at the bottom: The egg is older, but still safe to cook and eat.
- Floats to the top: The internal air pocket has grown larger due to moisture loss over time. Discard floating eggs.
Visual Inspection
After cracking, examine the white and yolk. A cloudy egg white indicates exceptional freshness, while a clear white means the egg is older. A flat, runny yolk paired with a watery white points to an older egg that is still fine to scramble or bake with, provided it passes the smell test. Discard any egg showing pinkish or iridescent discoloration inside the white, as this signals bacterial spoilage.
Common Egg Storage Mistakes
Small habits can shorten the life of your groceries. Avoid these frequent missteps to keep your eggs fresh longer.
- Washing eggs before storage: Commercial eggs arrive cleaned with a protective cuticle coating that blocks bacteria. Washing them at home strips this natural barrier.
- Storing on the door: Frequent temperature spikes cause premature spoilage.
- Leaving cartons uncovered: Unprotected shells absorb odors from onions, cheese, and leftovers.
- Freezing eggs in their shells: Liquid expands when frozen, causing the shell to crack. Crack eggs into a container and whisk them lightly before freezing.
Frequently Asked Questions
Can you eat eggs past the sell-by date?
Yes. The sell-by date tells retailers how long to display the product. As long as your refrigerator stays cold and the eggs pass the visual and smell tests, they remain safe to eat weeks past that date.
Why do some floating eggs still taste fine?
The float test measures air cell size, not spoilage. An older egg absorbs air through its porous shell, making it buoyant. It might be entirely safe to eat if stored properly, though the texture becomes better suited for hard-boiling or baking rather than frying.
Should you store washed farm-fresh eggs in the fridge?
Unwashed farm-fresh eggs retain their natural protective bloom and can sit on the counter for a short time, but refrigeration extends their life significantly. Once you wash a farm-fresh egg, you must refrigerate it immediately.
What is the safest way to freeze leftover raw eggs?
Crack the yolks and whites together, whisk them gently until blended, and pour them into a freezer-safe container. Add a pinch of salt or sugar per cup of eggs if you plan to use them for savory or sweet dishes later, which prevents the yolks from becoming gelatinous.
