Most refrigerated eggs last longer than many people expect, but the answer depends on what kind of egg you are storing. Raw eggs in the shell can generally be refrigerated for 3 to 5 weeks after purchase. Hard-boiled eggs should be used within 1 week, while separated raw yolks or whites keep for only 2 to 4 days.
Those time ranges assume the eggs were handled safely and kept at 40°F (4°C) or below. A carton date, a float test, or a normal smell cannot prove that an egg is free of harmful bacteria, so storage time and temperature still matter.
- Raw eggs in the shell: 3 to 5 weeks after purchase
- Hard-boiled eggs: 1 week after cooking
- Raw egg whites or yolks: 2 to 4 days
- Cooked egg dishes: 3 to 4 days
Egg refrigerator storage times at a glance
| Egg type | Refrigerator time | Start counting from |
|---|---|---|
| Raw eggs in shell | 3–5 weeks | Purchase date |
| Hard-boiled eggs, peeled or unpeeled | 1 week | Cooking date |
| Raw whites or yolks removed from shell | 2–4 days | Separation date |
| Cooked egg dishes | 3–4 days | Cooking date |
The U.S. Food and Drug Administration recommends using shell eggs within 3 weeks for best quality. The broader federal cold-storage chart gives a 3-to-5-week refrigerated range. Quality can decline before the end of a storage window, so it is sensible to use older eggs first.
Egg Storage Date Guide
Choose what you are storing, then enter the date you purchased, cooked, or separated it. The guide will calculate the applicable date range from federal storage recommendations.
This guide counts calendar days using FDA and FoodSafety.gov storage ranges. It cannot evaluate temperature history, contamination, damaged shells, or whether an individual egg is safe.
Where should eggs be stored in the refrigerator?
Keep eggs in their original carton on a shelf in the main refrigerator compartment—not in the door. A shelf provides a more stable temperature, while the door warms each time it is opened. The carton also protects the shells and keeps the purchase and carton dates available.
Use a refrigerator thermometer rather than relying only on the control dial. The refrigerator should stay at 40°F (4°C) or below. Put eggs away promptly after shopping, and avoid repeatedly moving refrigerated eggs in and out of cold storage.
What does the date on an egg carton mean?
Cartons may show a sell-by, use-by, expiration, or pack date, depending on the processor and state requirements. These dates can help with inventory and quality, but they do not replace safe refrigeration. For the federal 3-to-5-week storage guidance, count from the date you purchased the eggs and keep the carton as a reminder.
If you no longer know when the eggs were bought, a carton date can provide context, but it cannot reconstruct how long the eggs have been in your refrigerator or whether they stayed cold. When the history is uncertain—especially for a child, an older adult, a pregnant person, or someone with a weakened immune system—the cautious choice is to discard them.
Can a float test tell whether an egg is safe?
No. An egg tends to float as its internal air cell grows with age, so the test may suggest that an egg is older. It does not detect Salmonella or show how the egg was handled. Likewise, a bad odor after cracking is a clear reason to discard an egg, but a normal smell does not prove that it is safe.
Crack eggs one at a time into a separate small bowl before adding them to a recipe. This makes obvious spoilage or shell fragments easier to spot without ruining the other ingredients. Do not buy or use eggs with cracked shells, and do not wash eggs before refrigerating them because splashing can spread germs around the kitchen.
When should refrigerated eggs be discarded?
- The shell was cracked when purchased, or its safe handling history is unknown.
- The egg has passed the applicable refrigerated storage window.
- It has an unusual odor or appearance after cracking.
- Cooked eggs or egg dishes sat out for more than 2 hours—or more than 1 hour above 90°F (32°C).
- During a power outage, the eggs were above 40°F for 2 hours or more. When temperature history cannot be confirmed, discard them rather than tasting them.
For dishes that will remain raw or lightly cooked, such as homemade Caesar dressing or some desserts, the FDA recommends pasteurized shell eggs or pasteurized egg products. Cook regular eggs until the yolk and white are firm, and cook egg-containing dishes to 160°F (71°C).
Can eggs be frozen?
Do not freeze eggs in their shells. To freeze whole raw eggs, crack them, beat the whites and yolks together, and place them in a labeled freezer-safe container. Raw whites can also be frozen separately. Federal guidance lists up to 1 year for frozen eggs, although quality may change over time.
The bottom line
Raw shell eggs generally keep for 3 to 5 weeks after purchase when continuously refrigerated at 40°F or below, with 3 weeks being the FDA's best-quality target. Hard-boiled eggs last 1 week; separated raw eggs and cooked egg dishes have much shorter windows.
Write the purchase or cooking date on the carton, store eggs on an interior shelf, and use the oldest ones first. If refrigeration history is uncertain, a float test or sniff test is not a safety guarantee.
