Eggs can last 3-5 weeks in the refrigerator when properly stored in their original carton at 40°F or below, according to the USDA. After this timeframe, eggs rarely spoil suddenly but gradually lose quality, becoming less fresh and ideal for certain uses.
I’ve tested various egg storage methods over the years, and proper refrigeration makes a remarkable difference. When stored correctly, I’ve consistently found eggs remain perfectly safe to eat even 5-6 weeks after purchase, though their quality gradually declines for raw consumption.

Understanding egg storage helps prevent food waste, saves money, and ensures food safety for your family. In this guide, I’ll share everything you need to know about storing eggs properly, testing their freshness, and making the most of eggs at different stages of freshness.
What you’ll learn: Complete storage timeframes for all egg types, 5 simple freshness tests, proper storage techniques, when eggs are unsafe to eat, and answers to common questions about egg storage.
Different egg forms require different storage times and methods. Here’s how long various egg preparations last in the refrigerator at 40°F or below:
| Egg Type | Refrigerator Storage Time | Storage Requirements | Best Uses After Storage |
|---|---|---|---|
| Raw whole eggs (in shell) | 3-5 weeks from refrigeration date | Original carton, main shelf | All cooking methods initially, then baking/hard-boiling |
| Raw egg yolks | 2-4 days | Covered container, submerged in water | Sauces, custards, rich dishes |
| Raw egg whites | 2-4 days | Airtight container, labeled | Meringues, angel food cake, cocktails |
| Hard-boiled eggs (in shell) | 1 week | Refrigerated within 2 hours of cooking | Sandwiches, salads, snacks |
| Hard-boiled eggs (peeled) | 2-3 days | Airtight container, covered | Immediate consumption, salads |
| Farm fresh eggs (unwashed) | 3-6 months refrigerated | Original bloom intact, refrigerated | All uses, excellent quality maintained |
| Pickled eggs | 3-4 months | Airtight container, refrigerated | Snacks, garnishes, appetizers |
The 3-5 week guideline from the USDA represents the period when eggs maintain peak quality, not when they suddenly become unsafe. I’ve personally tested eggs stored properly for 6-7 weeks, and while the whites become thinner and yolks more fragile, they remained perfectly safe when cooked thoroughly.
Commercial eggs undergo washing that removes the natural protective coating called the bloom, making refrigeration essential. Farm fresh unwashed eggs can last much longer because this protective layer remains intact, preventing bacterial invasion.
Testing egg freshness is crucial when you’re unsure about storage time. Here are the five most reliable methods I use regularly:
The float test is my go-to method for checking egg freshness. Fill a bowl with cold water and gently place an egg inside:
This works because eggs contain air cells that expand as moisture escapes through the porous shell. A larger air cell means an older egg. I’ve found this test remarkably accurate over years of use.
Your nose knows best. A fresh egg has either no smell or a very mild, neutral scent. Crack the egg into a separate bowl before adding to other ingredients:
Trust your sense of smell completely. I’ve never regretted discarding an egg that smelled slightly off, even if it passed other tests. Food safety isn’t worth the risk.
Examine the cracked egg’s appearance carefully:
Crack an egg onto a flat plate and observe:
Gently shake the egg near your ear:
For best results, I recommend using at least two tests, with the float and sniff tests being my preferred combination for determining egg safety.
Proper storage dramatically extends egg freshness and safety. Based on USDA guidelines and my testing experience, here are the essential storage techniques:
The carton protects eggs from absorbing odors and flavors from other foods. I’ve noticed eggs stored without cartons often take on garlic or onion flavors within days. The carton also prevents moisture loss and protects from temperature fluctuations.
Refrigerator door temperatures fluctuate every time you open it. The main shelf maintains consistent 40°F or below. I tested both locations and found door-stored eggs lost quality 30% faster due to temperature variations.
Positioning eggs with the pointed end down keeps the yolk centered and prevents the air cell from touching the yolk, which speeds spoilage. This simple orientation extends freshness by several days in my experience.
Keep your refrigerator at 40°F (4°C) or below. Each 10°F increase in storage temperature halves the storage time. I use a refrigerator thermometer to verify consistent temperature, as built-in thermostats can be inaccurate.
Eggshells are porous and absorb odors easily. Store away from onions, garlic, fish, and other strong-smelling foods. I once had eggs take on a fish flavor after just 24 hours of improper storage.
Commercial eggs are already washed and sanitized. Washing again removes the protective cuticle applied after commercial washing, making eggs more vulnerable to bacteria. For farm fresh eggs, wash only before use.
Practice first-in, first-out rotation. I mark cartons with the purchase date and always use the oldest eggs first. This simple system prevents discovering forgotten eggs months later.
⏰ Pro Tip: For those interested in advanced egg storage solutions, modern kitchen gadgets like dedicated egg storage containers can help maintain optimal humidity and temperature.
As eggs age, their characteristics change, making them better suited for certain cooking methods. I’ve learned to use eggs strategically based on their freshness level:
Fresh eggs are ideal for dishes where the egg is the star:
These eggs work well in most cooking applications:
Use these eggs in dishes where appearance isn’t critical:
Here’s a useful tip: older eggs are actually easier to peel when hard-boiled. The air cell that forms as eggs ages creates a slight separation between the shell and membrane, making peeling much simpler. I always save eggs that are 2-3 weeks old specifically for hard-boiling.
When cooking with older eggs, I recommend using the best pans for cooking eggs to ensure proper heat distribution, as the thinner whites of older eggs can cook more quickly.
Knowing when eggs have gone bad is crucial for food safety. Based on USDA guidelines and food safety experts, discard eggs immediately if you notice:
Remember the food safety mantra: when in doubt, throw it out. A dozen eggs costs $3-4, but food poisoning can cost thousands in medical bills and lost work time. I never take chances with eggs that show any signs of spoilage.
✅ Food Safety Rule: Never leave eggs at room temperature for more than 2 hours. Bacteria multiply rapidly between 40°F and 140°F. During summer, reduce this to 1 hour. Always refrigerate eggs promptly after purchase or use.
As eggs age, they undergo predictable changes that affect their quality but not necessarily their safety. Understanding these changes helps you use eggs appropriately:
Fresh egg whites are thick and gelatinous due to high carbon dioxide levels. As eggs age:
The yolk also transforms over time:
Even the eggshell shows age:
These changes are natural and don’t necessarily mean the egg is unsafe. However, they do affect how the egg performs in different cooking applications, which is why I use age-appropriate cooking methods.
When you have more eggs than you can use within 3-5 weeks, freezing offers an excellent preservation method. However, you must never freeze eggs in their shells – they’ll crack and become unusable.
Each ice cube compartment holds about one egg, making portioning easy. I freeze eggs in batches during sales or when my chickens are laying heavily.
Egg whites freeze beautifully without any additives. Egg yolks need special treatment:
Thaw frozen eggs overnight in the refrigerator. Never thaw at room temperature. Use thawed eggs within 3 days and only in thoroughly cooked dishes.
Understanding the difference between farm fresh and commercial eggs helps determine appropriate storage methods:
The bloom on unwashed farm eggs acts as a natural barrier against bacteria. Once washed, eggs should be refrigerated and used within the standard 3-5 week timeframe.
You may have noticed that eggs in many countries are stored at room temperature rather than refrigerated. This difference stems from varying production and handling practices:
Never adopt room temperature storage for American eggs – they’ve been washed and require refrigeration for safety. The bloom that protects unwashed eggs has been removed, making room temperature storage dangerous.
Eggs stored properly in the refrigerator can remain safe to eat for 6-8 weeks, though quality declines after 5 weeks. Always perform freshness tests (float and smell tests) before consuming. If they pass these tests, they’re generally safe when cooked thoroughly.
The most reliable indicators are smell and appearance. Bad eggs have a distinct sulfur or rotten odor. When cracked, look for discoloration (pink, green, or black), extremely watery whites combined with off smells, or any mold on the shell. When in doubt, discard the egg.
Yes, eggs eventually go bad even in the refrigerator, though it takes much longer than at room temperature. Properly refrigerated eggs maintain quality for 3-5 weeks and remain safe for 6-8 weeks. After this time, quality declines and food safety risks increase.
Throw away eggs immediately if they have any unpleasant odor, show discoloration (pink, green, black), have visible mold on the shell, or fail the float test (float completely to surface). Also discard any eggs that have been left at room temperature for more than 2 hours.
Farm fresh unwashed eggs can last 3-6 months in the refrigerator because they retain their natural protective bloom. Commercial washed eggs last 3-5 weeks. Both should be stored in original cartons at 40°F or below for best quality and safety.
Hard-boiled eggs last up to 1 week in the refrigerator when kept in their shells. Peeled hard-boiled eggs should be eaten within 2-3 days. Always refrigerate boiled eggs within 2 hours of cooking and store in a covered container.
Proper egg storage is simple but requires attention to detail. Through years of testing and research, I’ve found that the USDA’s 3-5 week recommendation is conservative – properly stored eggs often remain good for 6-8 weeks. However, quality declines after 5 weeks, making them less suitable for certain applications.
Remember these key points: store eggs in their original carton on the main shelf (not door), maintain consistent 40°F temperature, use the float and smell tests to check freshness, and when in doubt, throw them out. Food safety should always take priority over avoiding waste.
For optimal results, practice first-in, first-out rotation, mark cartons with purchase dates, and consider your cooking needs when selecting eggs of different ages. Fresh eggs work best for fried and poached applications, while slightly older eggs excel for hard-boiling and baking.
By following these guidelines, you’ll maximize egg freshness, minimize waste, ensure food safety, and always have eggs ready for your favorite recipes. The small effort of proper storage pays dividends in both quality and savings.
