Eggs are often safe to eat for 3 to 5 weeks past the sell-by date if they have been kept in the refrigerator. The sell-by date is a quality guideline for stores, not a strict expiration date. Proper refrigeration keeps eggs fresh longer than many people expect.
How Long Past The Sell By Date Are Eggs Good?
According to the U.S. Department of Agriculture, eggs can be refrigerated for 3 to 5 weeks after the purchase date. The sell-by date is set by egg producers to indicate when stores should stop selling the eggs. It is not a safety deadline. Many eggs are still safe to eat for several weeks beyond that date.
The key factor is continuous refrigeration. Eggs kept at 40°F or below can remain safe and maintain acceptable quality for several weeks past the sell-by date. Once you bring eggs home, store them in the coldest part of the refrigerator, not in the door where temperatures fluctuate.
What Does the Sell-By Date Actually Mean?
The sell-by date is a label for retailers, not for consumers. It tells the store how long to display the eggs for sale. Under federal regulations, the sell-by date cannot be more than 30 days from the date the eggs were packed. This means eggs are typically still fresh when you buy them.
After you buy eggs, the expiration date is not the same as the sell-by date. Many egg cartons also have a “use by” or “expiration” date. That date is closer to a quality guideline, but even that is not a strict safety cut-off. Eggs stored properly can still be used 1 to 2 weeks after the “use by” date.
The key point: the date on the carton is about peak quality, not food safety. If eggs have been refrigerated continuously, they are likely safe beyond any printed date.
How to Test If Eggs Are Still Fresh
There are a few ways to check egg freshness at home. The most well-known is the float test. Place an egg in a bowl of water. A fresh egg will sink and lie flat on its side. An older egg will stand upright or float. This happens because the air cell inside the egg grows as it ages.
However, the float test does not tell you if the egg is safe to eat. It only indicates freshness. A floating egg may still be safe if cooked thoroughly. The safest way to judge an egg is to crack it open and look for signs of spoilage. A bad egg will have an unpleasant sulfur smell. It may also have a discolored white or yolk, or a runny, thin white that spreads widely. If the egg looks or smells off, throw it away.
Another test is to shake the egg near your ear. A fresh egg makes almost no sound. An older egg will slosh because the white has thinned. This is also a freshness indicator, not a safety test.
How to Store Eggs for Maximum Freshness
Storage matters more than the date on the carton. Keep eggs in their original carton in the coldest part of the refrigerator, not in the door. The door is the warmest spot and temperature changes each time you open it. The main body of the fridge stays more consistent.
Do not wash eggs before storing. Commercial egg washing removes a natural protective coating called the bloom. Once washed, eggs need to be refrigerated. Washing them again at home can increase the risk of bacteria entering through the shell.
Eggs can also be frozen for long-term storage. To freeze whole eggs, beat them lightly and place in a freezer-safe container. Egg whites and yolks can be frozen separately. Frozen eggs will keep for up to a year. Thaw them in the refrigerator before using.
What Happens If You Eat Expired Eggs?
The main risk with old eggs is food poisoning from bacteria like Salmonella. Eggs are especially risky if the shell is cracked or the egg has been out of refrigeration for more than two hours. However, if the egg is refrigerated and the shell is intact, the risk is low even past the sell-by date.
Cooking eggs thoroughly kills Salmonella. That means cooking until both white and yolk are firm. Dishes like scrambled eggs, omelets, and hard-boiled eggs are safe if cooked properly. Runny yolks carry a higher risk, especially for older adults, pregnant women, young children, and people with weakened immune systems.
If you eat an egg that has gone bad, you may experience symptoms of food poisoning: nausea, vomiting, diarrhea, stomach cramps, and fever. These symptoms usually appear within 12 to 72 hours and last 4 to 7 days. Most healthy people recover without treatment, but severe cases require medical attention.
Do Older Eggs Lose Nutritional Value?
Eggs do lose some quality over time, but the nutritional value stays mostly the same. The protein, fat, vitamins, and minerals in eggs are stable for weeks when refrigerated. The main change is texture and flavor. Older eggs have thinner whites and less firm yolks. They may also absorb odors from the fridge. But they still provide the same basic nutrients as fresh eggs.
The exception is if the egg is spoiled. In that case, the breakdown of proteins and fats can produce harmful compounds. But a properly refrigerated egg past the sell-by date is unlikely to be spoiled if it looks and smells normal.
Frequently Asked Questions
Can you eat eggs 2 months past the sell-by date?
It is not recommended. While some eggs may still be safe if refrigerated continuously, the risk of spoilage and quality loss increases significantly after 5 weeks.
Does the float test tell you if an egg is safe?
No. The float test only indicates freshness, not safety. An egg that floats may still be safe if it passes the smell and visual check.
How can you tell if an egg is bad without cracking it?
You cannot reliably tell without cracking it. A bad egg often develops a bad smell only after the shell is broken. The float test gives a hint but is not definitive.
Should you wash eggs before using them?
No. Washing eggs at home can remove the protective coating and increase the risk of bacteria entering the shell. Crack and use them as is.
