How To Tell If Eggs Are Still Good?

How To Tell If Eggs Are Still Good

How do you know if your eggs have gone bad?

Simply fill a bowl with cold tap water and place your eggs in it. If they sink to the bottom and lay flat on one side, they are fresh and good to eat. A bad egg will float because of the large air cell that forms at its base. Any floating eggs should be thrown out.

Can you still eat eggs that float?

An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is old, but it may be perfectly safe to use. Crack the egg into a bowl and examine it for an off-odor or unusable appearance before deciding to use or discard it.

Is an egg still good if it stands up in water?

The float test: Do you know how to tell if an egg is fresh? If an egg sinks to the bottom of a bowl of water and lies sideways, it is very fresh; if it stands on one end in bottom of the bowl, it is less fresh but still good to eat. But if it floats to the surface of the water, indicating that air has permeated the shell, it is no longer fresh.

  • This simple test can be more reliable than the best-before date stamp each egg laid in the EU must bear.
  • But research in the UK has shown that consumers there are throwing away 720 million eggs every year – three times more than in 2008 and at a cost of £139 million (€161 million).
  • The scale of waste has been blamed on overcautious consumers relying on best-before dates to decide if eggs are fresh enough to eat, and the growing popularity of vegetarian and “flexitarian” diets has boosted overall sales.

Eggs are a good source of high-quality protein, and Irish registered dietician Paula Mee recommends eating up to eight a week in her recently published book, Mediterranean Mood Food. Last year sales of eggs in the UK were £7.2 billion (€8.3 billion) – a 4 per cent rise on the previous year – according to recent figures from the British Egg Industry Council.

  • But consumer research from the company behind the food waste app Too Good To Go, published on Tuesday, revealed that UK households binned 720 million eggs last year, compared with 241 million in 2008 according to Wrap, the government’s waste advisory body.
  • Last year sales of eggs in the UK were £7.2 billion (€8.3 billion) – a 4 per cent rise on the previous year – according to recent figures from the British Egg Industry Council.

The research also showed that 29 per cent of Britons throw away eggs solely because they are past their best before date. However, eggs are often still good and safe to eat long after the date on the packaging has passed. EU legislation requires that the maximum best before date on eggs must be 28 days from when they were laid.

The research found that just 23 per cent of Britons were familiar with the water test that reveals whether eggs are still fresh enough to eat. If eggs sink to the bottom of a bowl of cold water and lie flat on their sides, they are very fresh. If they are less fresh but still good to eat, they will stand on one end at the bottom.

If they float to the surface, they are no longer fresh enough to eat. This is because as the egg gets older, the size of the air sac inside increases, making it float. “If you’ve been throwing your eggs in the bin based on the dates on the box, you’ve probably been wasting perfectly good food,” said Jamie Crummie, the co-founder of Too Good To Go.

“Food waste is a huge problem – a third of all food produced globally is wasted. Small changes from each of us can make a big difference.” Too Good To Go is challenging the British public to use the water bowl test to check the freshness of their eggs to help cut down on edible food needlessly being binned.

Meanwhile, research by Wrap has shown that 20 per cent of people don’t realise that it is possible to freeze eggs. It has been suggested that dietary trends popularised by celebrities such as Joe Wicks have reinvigorated egg sales. In addition, the spike in egg consumption may be partly due to a change in advice from the Food Standards Agency in 2017 – almost 30 years after the UK salmonella crisis – stating that pregnant women, babies and elderly people could safely eat runny or even raw eggs.

Do eggs go bad after 2 months?

With proper storage, eggs can last a few weeks in the refrigerator and around 1 year in the freezer. But their quality may start to decline over time, resulting in changes in taste and texture. In the United States, eggs are considered a perishable item.

  1. This means they must be kept in the refrigerator to prevent them from going bad.
  2. However, eggs can last for a surprisingly long time when they’re stored properly.
  3. In fact, if you throw eggs out as soon as their expiration date arrives, you may be wasting money.
  4. This article covers everything you need to know about how long eggs last before going bad.

In the United States and certain other countries, including Australia, Japan, Sweden, and the Netherlands, eggs require refrigeration ( 1, 2 ). This is because eggs in these countries are washed and sanitized soon after they are laid in an attempt to prevent contamination with Salmonella, the bacteria often responsible for food poisoning from poultry products ( 3, 4 ).

Yet in addition to removing bacteria, washing an egg may damage its naturally protective cuticle. This can make it easier for bacteria to move through the shell and contaminate the egg ( 5 ). The presence of bacteria inside an egg is what eventually causes it to “go bad,” or rot. However, keeping an egg at refrigerator temperatures (below 40°F, or 4°C) slows the growth of bacteria and helps prevent it from penetrating the shell ( 6, 7 ).

In fact, refrigeration is so effective at controlling the growth of bacteria that in combination with an egg’s protective shell and enzymes, refrigerated eggs rarely go bad — as long as they have been handled and stored properly. Nevertheless, egg quality declines over time.

  1. This means that the air pocket in an egg grows larger and the yolk and whites become thinner and less springy.
  2. Eventually, it may simply dry up instead of going bad ( 8 ).
  3. Despite these changes, an egg may remain perfectly safe to eat for a long time ( 8 ).
  4. Eggs won’t stay good forever though, and there is a point at which you’ll want to throw them away.

summary Eggs rarely go bad if they have been handled properly and are stored in the refrigerator. However, they will decline in quality over time, and you’ll want to throw them away at some point. If eggs have been transported and stored properly, they can last for many weeks in the refrigerator and even longer in the freezer ( 8 ).

The Food and Drug Administration (FDA) requires all eggs to be kept below 45°F (7°C) from the time they are washed until they are purchased — but it’s just as important that eggs are handled and stored properly after you’ve bought them ( 9 ). This means you should refrigerate eggs quickly to prevent condensation from building up, which can facilitate the movement of bacteria through the shell ( 8 ).

Ideally, eggs should be stored in their original carton in the back of the fridge. This prevents them from absorbing odors and protects them from temperature fluctuations as the refrigerator door is opened and closed ( 2, 8 ). You can also use a thermometer to check that your refrigerator is at the proper temperature (below 40°F or 4°C) ( 10 ).

This chart explains how long eggs can be stored before going bad or becoming so low in quality (taste and texture) that it’s best to throw them out ( 8, 10 ): It is not recommended to freeze eggs in the shell. If you want to preserve them for longer than the recommended 3 – 5 weeks in the fridge, you can crack them into a freezer-safe container and keep them frozen for a year or more.

Eggs can be stored in the freezer indefinitely, but their quality will start to decline after a certain point. Additionally, make sure your freezer is below 0°F (-18°C) ( 10 ). When you’re ready to use them, move the container to the refrigerator to thaw and use within 1 week.

  1. If you live outside of the United States in a country where hens are vaccinated against Salmonella and eggs are not washed and refrigerated, eggs can safely be kept at room temperature for 1 – 3 weeks, if desired ( 11 ).
  2. However, after around 5 days at room temperature, the eggs’ quality will begin to decline.

And after about 21 days, an egg’s natural defenses will lose their effectiveness ( 11, 12 ). Eggs can be placed in the refrigerator or freezer after this point to extend their shelf life, but they will not last as long as eggs that have been kept in the refrigerator from purchase.

If you live in the United States or another country where eggs must be refrigerated, eggs should not be left at room temperature for more than 2 hours ( 8 ). summary Fresh eggs can be kept for 3–5 weeks in the fridge or about 1 year in the freezer. Store them in the original carton away from the door of the fridge to preserve quality.

If you’re not sure how long your eggs have been in the fridge, there are several ways to tell whether they are still good or not. The first step should be to check the sell-by or expiration date printed on the carton. If the current date is before this date, you’ve got nothing to worry about.

  1. Alternatively, look for the pack date.
  2. This will be printed as a three-digit number that corresponds to the day of the year that the eggs were washed and packaged.
  3. For example, January 1 is 001.
  4. If the eggs are less than 30 days from the pack date, you can be sure they’re still good ( 8, 13 ).
  5. However, your eggs may still be good for up to several weeks beyond these dates.

In this case, the best way to tell if an egg has gone bad is to conduct a sniff test. Other methods, such as candling or the float test, can only tell you if an egg is fresh but not if it has gone bad ( 8 ). Before conducting a sniff test, check if the shell has any cracks or a powdery or slimy appearance.

If so, toss the egg. If everything looks good, crack the egg open on a clean, white plate before using. Check for any discoloration or a funny smell ( 8 ). An egg that has gone bad will give off an unmistakable odor. If everything looks normal and the egg has no smell, then it is fine to use. However, it’s important to note that eggs contaminated with the bacteria Salmonella may look and smell completely normal, even though they can make you sick ( 8 ).

Therefore, be sure to cook eggs until both the white and yolk are firm in order to kill any bacteria that may be present. Foods containing eggs, like casseroles, should be cooked to a minimum internal temperature of 160°F (71°C) ( 2, 8 ). Although many people prefer undercooked eggs, certain populations should avoid this because they are at an increased risk of foodborne illness, including young children, older adults, people who are pregnant, and individuals with weakened immune systems ( 8 ).

  • For recipes that call for raw eggs, like Caesar salad dressing, it’s best to use pasteurized eggs ( 2, 8 ).
  • Read this article to find out more about how to tell if an egg is good or bad.
  • Summary If an egg is past the sell-by or expiration date, it may still be good to use.
  • Crack the egg onto a clean, white plate.

If it looks and smells normal, then it’s okay to use. If your eggs are not the freshest but haven’t gone bad, there are certain ways to best use them. Likewise, there are certain uses better reserved for fresh eggs. Older eggs are ideal for boiling. As an egg ages and its air pocket gets larger, it becomes easier to peel.

Older eggs are a good choice for hard-boiled eggs, deviled eggs, or egg salad ( 8 ). Older eggs can also be used for scrambled eggs, omelets, casseroles, or quiches. However, fried eggs and poached eggs should ideally be made with fresh eggs. The longer an egg sits in the fridge, the runnier its yolk and whites will be.

This means that using an older egg might result in a runny mess instead of a firm fried egg or a compact poached egg. Additionally, an old egg may not be as effective a leavening agent for baking ( 8 ). Nevertheless, older eggs can be used for almost any purpose.

  • If you’re not sure how long an egg has been sitting in the fridge, crack it open and conduct a sniff test first.
  • Summary Boiled eggs are easier to peel if they are made with older eggs.
  • Older eggs are also fine to use for scrambled eggs, omelets, casseroles, or quiches.
  • Fresh eggs are best for frying, poaching, or baking.

If you throw your eggs out once the date on the carton has passed, you may be wasting perfectly good eggs. With proper storage, eggs can last for at least 3 – 5 weeks in the fridge and about 1 year in the freezer. The longer an egg is stored, the more its quality declines, making it less springy and more runny.

Can you eat eggs 3 months old?

It can be safe to eat expired eggs if you store them right. But it’s important to know the difference between eggs that are expired but safe and eggs that are spoiled. Eggs are a staple food in households around the world. They’re a nutritious and affordable source of protein.

Plus, they make a quick meal any time of day, so it’s no wonder people like to keep eggs on hand. However, if you’ve ever left a carton of eggs in the fridge for a few weeks, you may have wondered whether they were still safe to eat. Egg cartons often have a date printed on them, such as a “best before” or “sell by” date.

These dates make it easier to know how old the eggs are. But if you store them properly, eggs can last far beyond their expiration date and still be safe to eat. On the other hand, eggs that have been contaminated or stored improperly can spoil and contain harmful bacteria.

  • This article explains when it’s safe to eat expired eggs and how to store your eggs for maximum freshness.
  • In-shell eggs that have been washed and stored in the refrigerator stay fresh for an average of 3–5 weeks ( 1 ).
  • Compared with other perishable proteins, eggs actually have a notably longer shelf life.

Once they’ve been opened, most milk and meats stay fresh in the refrigerator for only 1 week at most ( 1 ). Still, when you buy eggs at the store, it can be hard to know how long they’ve been sitting on the shelf and how much longer they’ll remain fresh once you bring them home.

  1. This is where date labels printed on egg cartons come in handy.
  2. Date labels help you determine how long your eggs will stay fresh and safe to eat.
  3. Eggs are often labeled with the date they were processed and packed or an expiration date, though some eggs may not have any date labels at all, depending on the source and the regulations in your area.

Here are a few of the most common date labels on egg cartons in the United States ( 2 ):

Best-by. The eggs will be at peak quality and flavor if you eat them before this date, which is set by the manufacturer. As long as the eggs don’t show signs of spoilage, they can still be sold and are considered safe to eat after this date. Sell-by. This date can be no more than 30 days after the pack date of the eggs. At the sell-by date, the eggs may be around 4 weeks old. EXP. Shorthand for “expiration,” this is another way to label a “sell-by” date. Pack date. This notes the day the eggs were processed and packed into the carton. It’s displayed as a three-digit number from 1–365. This method numbers the days of the year consecutively, so January 1 is 001, January 2 is 002, December 31 is 365, and so on.

With proper storage, eggs typically stay fresh 3–5 weeks past the pack date — the date they were gathered, cleaned, and stored in refrigeration. After 5 weeks, your eggs might start to decline in freshness. They could lose flavor and color, and the texture might even be somewhat altered.

  1. As the weeks go on, eggs will continue to diminish in quality even if you refrigerate them.
  2. Still, as long as they remain free of contamination from bacteria or mold, they may still be safe to eat for days or weeks longer.
  3. Summary Eggs have an average shelf life of 3–5 weeks.
  4. With proper storage, most eggs are still safe to eat after 5 weeks, though their quality and freshness will likely begin to decline.

Eggs are a notoriously high risk food for the growth of Salmonella, a type of bacteria that live in and affect the digestive tracts of animals and humans ( 6, 7, 8 ). Salmonella bacteria are one of the most common causes of foodborne illness, causing side effects like fever, stomach pain, vomiting, and diarrhea ( 4 ).

  • It’s possible that Salmonella could be present on the inside or outside of eggs when you buy them.
  • The bacteria could also continue to multiply even while eggs are in the refrigerator.
  • This means that even if you’re doing everything right when it comes to storing fresh eggs, there may still be a small chance you could get sick from Salmonella,

The best way to avoid contracting a foodborne illness from a contaminated egg is to always cook your eggs to a minimum internal temperature of 160°F (71°C) ( 3, 7, 9 ). No kitchen thermometer on hand? Not to worry — just be sure to cook your eggs until the yolks are firm and the whites are no longer runny or translucent.

Can I eat eggs that expired a month ago?

How Eggs Are Dated – “Those expiration dates are on some egg cartons to make sure that retailers don’t keep eggs on shelves past a certain date,” Maloberti says. “However, eggs can be safely eaten two to three weeks past that date. Depending on where, the expiration date may be labeled as Sell By, Use By, Exp.

  • By or Best By.” If you’d like to dig deeper, it’s good to know that cartons from plants that produce Department of Agriculture-graded eggs must display what’s called a Julian date, which is the day of the year the eggs were packed.
  • On those egg cartons, if an expiration date appears, it can be no more than 30 days after the pack date.

“As long as they’re kept properly refrigerated at 40°F or lower, fresh eggs are safe to eat four to five weeks beyond the carton’s Julian date,” Maloberti says. How to find that date? “It’s usually found on the short side of the carton and represents the consecutive days of the year, with the number 001 as January 1 and December 31 as 365.” EatingWell

Do eggs expire if refrigerated?

Information. Eggs may be refrigerated three to five weeks from the day they are placed in the refrigerator. The ‘Sell-By’ date will usually expire during that length of time, but the eggs will be perfectly safe to use. Always purchase eggs before the ‘Sell-By’ or EXP (expiration) date on the carton.

How do you test eggs by floating?

Test Eggs for Freshness: Tutorial – First, you’ll need to gather your eggs. We collected some farm-fresh eggs this morning! We’ll test these against some eggs that have been sitting in the fridge for a few weeks. Next, fill a bowl or jar with cold water. Place your eggs in the water. WHAT HAPPENS, AND WHAT IT MEANS

If your eggs sink to the bottom and lie flat on their sides, they are very fresh. If your eggs stand on one end at the bottom, they are a few weeks old, but still fine to eat. If your eggs float to the surface, they are no longer fresh. Don’t eat them!

WHY DOES THE FLOAT TEST WORK? The reason this method works is that eggshells are porous, which means they allow some air to get through. Fresh eggs have less air in them, so they sink to the bottom. Older eggs have had more time for the air to penetrate the shells, so they are more buoyant and will float.

Can you check your egg count?

The AMH Test – Each egg in a woman’s ovaries lives inside a follicle, a fluid-filled sac that contains cells that support egg maturation and produce hormones. AMH is one of those hormones. The level of AMH in a woman’s blood helps doctors estimate the number of follicles in her ovaries; the more follicles a woman has, the more eggs she can release, and the better her chances of pregnancy.

  • The AMH test isn’t 100 percent predictive of pregnancy, but it provides physicians with a rough estimate to work with, says David B.
  • Seifer, MD, an REI specialist who discovered AMH in women’s follicular fluid in 1993 and co-developed AMH as a serum test to assess ovarian reserve in 2002.
  • It’s most useful in terms of having an idea of what treatment to use, how to use that treatment, and even perhaps the time course in which it might be applied,” he says.

A higher level of AMH isn’t necessarily the goal, Dr. Seifer explains. “There’s a normal range, and then there’s what is considered too high. That often indicates something like polycystic ovarian syndrome (PCOS; a hormonal disorder often linked to fertility problems),” he says.

  • Or too low could mean a woman is going through a premature or accelerated aging process.” The AMH blood test has become more common in the past 15 years, but another way to determine a woman’s ovarian reserve is to conduct an antral follicle count during a transvaginal ultrasound.
  • This method, which entails counting the follicles seen on the screen, is also useful, along with AMH, explains Amanda N.

Kallen, MD, an REI specialist. “Ultrasound is somewhat subjective, so you’re still relying on someone’s eyes to see and count, and it can vary somewhat between person to person,” she says.

How old is an egg if it floats?

Not Quite as Fresh Egg – The egg in the photo above is a couple of weeks old. You can see that the blunt end of the egg has started to rise up off the bottom of the glass a bit. As the egg ages and air seeps through the pores in the eggshell, the air sac inside the egg enlarges as the inside of the egg start to dry out.

Can you eat 2 week old hard boiled eggs?

Eating a two-week-old boiled egg that still tastes and smells okay should generally be safe, as long as it has been stored properly and not exposed to any contaminants. However, it is important to note that the quality and freshness of eggs can deteriorate over time, increasing the risk of bacterial contamination.

What does it mean when eggs float when boiling?

Why Do Rotten Eggs Float? – As an egg ages, this air cell grows larger as the yolk and white further contract. Therefore, ‌ an older egg is less dense and more likely to float ‌ in boiling water. Store-bought eggs can last several weeks beyond their sell-by date or expiration date. To reduce the chances of eggs going bad, keep them refrigerated.

Can you cook with expired eggs?

How long do eggs last? – Store-bought refrigerated eggs can last several weeks if you transport and store them correctly. It’s important to keep them cold once you bring them home — below 40°F (4°C), to be eggs-act, according to the FDA, You should also store them in the back of the fridge, where the temp is more consistent.

  • A 2011 research review suggested that steady temperatures may help eggs’ natural defenses fight off Salmonella bacteria.
  • Pro tip: Keep your eggs in their original storage container.
  • The carton can protect the eggs from absorbing nearby odors.
  • Because no one wants an omelette that tastes like an old tomato — trust us 🤮.) Most nonrefrigerated eggs will start to drop in quality after a week.

And eating expired eggs starts to get really risky after 21 days, according to a 2007 study, If you’ve cooked your eggs, avoid leaving out cooked eggs for more than 2 hours. A popular way to check if an eggo is good-o is the float test. As an egg ages, moisture leaves through the shell.

  1. Fill a bowl with room-temp water.
  2. Gently place the egg in the water.
  3. If it sinks to the bottom, it’s safe to eat.
  4. If it tilts upwards or floats, it’s time to toss it out.

Or you could just try meowing at it and see how far you get. This method is better, though. First things first, always check the expiration date on the carton. Eggs are totes fine to eat before the time period after that expiration date. You can even eat them afterward if you’ve followed the steps for safe storage. Here are some other ways to put your egg to the test:

  • Check to see if the shell is cracked.
  • Make sure the inside of the egg isn’t discolored.
  • Look for slimy or powdery patches on the shell.

You can also try the sniff test. An odorless egg is prime breakfast sammie material. But one that smells like low tide on a summer’s day is a no-go. Next time your parents say your partner seems like a “bad egg,” check your boo’s jacket for slimy or powdery patches.

Just be sure to keep your eggs egg-cellent by storing them correctly. If you don’t know if an egg is good or not, you can try the float test or give it a whiff.

Why you should not keep eggs in the fridge?

5 reasons to not store eggs in the refrigerator Eggs are a natural food product and being rich in protein and other organic compounds they are more prone to spoilage. However, nature has blessed eggs with natural defense and they are actually sturdier than we can imagine. Eggs are a natural food product and being rich in protein and other organic compounds they are more prone to spoilage. However, nature has blessed eggs with natural defense and they are actually sturdier than we can imagine. Read on to know why eggs do not necessarily need refrigeration to store them safely. Majority of us have been storing eggs in the refrigerator and almost all refrigerator manufacturing companies offer a separate egg tray with all their units. But, there is a new study that suggests to not store poultry eggs in the refrigerator any more.

Read more For far too long it has been believed that refrigerating eggs saves them from getting spoilt and reduces the risk of getting salmonella induced food poisoning, as the refrigeration controls the multiplication of this harmful bacteria. However, here are the reasons which make it viable to store eggs unrefrigerated.

Eggs do not rot. Eggs that are stored at the room temperature do not rot fast as opposed to the ones that are refrigerated. Also, some of them tend to turn sour when taken out after being stored in extremely cold temperatures. They are better for baking. All the baking recipes recommend using eggs that are stored at room temperature as they tend to whip way better than the ones which are refrigerated. Buy the ones with cuticle. There is no need to refrigerate the eggs which have the cuticle intact, as it means they are quite fresh. Reduces growth of bacteria on the shell. The eggs stored in cold temperature tend to undergo condensation when they are taken out to room temperature. This promotes the growth of bacteria over the egg shell, thereby contaminating the egg and making it harmful for human consumption. Refrigerate only if you suspect salmonella infection. However, it is recommended that you refrigerate the eggs if you suspect salmonella infection because storing them at room temperature will infect other eggs as well whereas, refrigeration will kill the harmful bacteria. In either case, you must not keep the eggs for too long and try to use all that you have purchased within a couple of days. : 5 reasons to not store eggs in the refrigerator

Eggs may be refrigerated three to five weeks from the day they are placed in the refrigerator. The ‘Sell-By’ date will usually expire during that length of time, but the eggs will be perfectly safe to use. Always purchase eggs before the ‘Sell-By’ or EXP (expiration) date on the carton.

What color is a bad egg yolk?

Download Article Download Article Have you ever been in the middle of baking or cooking, only to notice your eggs are past the “sell-by” date? Before you throw your eggs away, try a few tricks to see if the eggs are actually bad.

  1. 1 Place the egg in question in a bowl or wide glass of cold water and see if it floats. There is a tiny air pocket inside eggs, and over time more and more air passes through their porous shells and into the egg. As more air enters the egg, the air pocket grows larger, making the egg more buoyant.
    • If the egg lays on its side on the bottom of the bowl, it is at peak freshness,
    • If the egg stands upright on one end but is still touching the bottom, it is aging past its prime but is still safe to eat.
    • If the egg is floating, it is not a fresh egg. This does not necessarily mean it’s bad or unsafe to eat. You should test the egg by cracking it open and looking for (or smelling) signs that it has gone bad.
  2. 2 Hold the egg up to your ear and shake it, listening for a sloshing sound. As the egg ages and moisture and carbon dioxide escapes through the shell, the yolk and white begin to dry out and shrink, and the air pocket in the egg becomes bigger. A larger air pocket gives the egg more room to move around inside the shell and create a sloshing sound.
    • A fresh egg should not make much, if any, sound when you shake it.
    • A sloshing egg only indicates that the egg is old and does not mean the egg is unsafe for consumption.

  3. 3 Crack the egg open on a plate or in a large bowl and check the quality of the yolk and white. The integrity of the egg will lessen as it ages, so it won’t hold together as well as a fresh egg. Notice if the egg seems to spread over a wide distance on the plate, or if it stays relatively compact. An egg that spreads or seems a little watery has a thinner white and is past its peak freshness.
    • If the yolk is flat and breaks easily, the egg is old.
    • If the yolk moves around easily, this means the chalazae (the thicker strands of egg white that hold the yolk in place) have weakened and the egg is aging.
    • Look at the color of the egg white, A cloudy white indicates a very fresh egg. A clear white means the egg is older (but may still be edible).

  1. 1 Break the egg open and notice if it smells. This is the best indicator of a bad egg. A bad egg will have a pungent, foul odor when you break it open. The sulfurous smell will be obvious as soon as the egg is cracked (and possibly before), and the egg should be thrown out.
    • A bad egg will have this foul smell, regardless of whether it is raw or cooked.
  2. 2 Break the egg into a small dish and inspect the color. The color of the yolk will change based on the diet of the hen who laid it, so the shade of yellow or orange nothing to do with freshness. Instead, inspect the egg white, or albumen. If it is pink, green, or iridescent, the egg has been contaminated by Pseudomonas bacteria and is not safe to eat.
    • If the yolk of a hard-cooked egg has a green ring around it, this means the egg has been overcooked or was cooked in water with a high iron content. This egg is still safe to eat,
    • If there is a blood or meat spot on the egg, it is still safe to eat and does not mean the egg is contaminated or has gone bad. A blood spot occurs when a blood vessel ruptures when the egg is forming and has nothing to do with freshness.

  1. 1 Check the “sell-by” date on the package. The sell-by date may also appear as “not to be sold after” or “EXP.” This date is, at most, 30 days from the day the eggs were packaged. Eggs that are kept refrigerated and are not broken should be good for at least 1 month beyond the sell-by date.
    • The sell-by date appears as month/day in the United States. So eggs that must be sold by March 15th are labeled 03/15.
    • “Sell-by” refers to the last date the eggs should be available for the public to purchase. Eggs should be pulled from the shelf after this date. It does not mean the eggs are bad or rotten after this date.
  2. 2 Check the “best-by” date on the package. The best-by date may also be labeled as “use by,” “use before,” or “best before.” The best-by label must be within 45 days of the date the eggs were packaged. Try to use these eggs within two weeks after the best-by date.
    • “Best-by” refers to the period of time eggs are at their peak freshness, with the best texture, flavor, and binding and thickening properties. It does not mean the eggs are bad or rotten after this date.
  3. 3 Use the 3-digit code that tells you when the eggs were packaged. Sell-by or best-by dates are not required by federal law (some states require them, other states forbid them), but all eggs must be labeled with the date they were packaged. This date usually appears as a 3 digit code using the Julian date calendar.
    • Look for the Julian date on the end of the carton. You’ll see the plant code (a letter P followed by numbers) indicated where the eggs were packaged, and beside it you should find the Julian code.
    • The European Union also requires that eggs are marked with a pack date. Even if eggs are sold loose and not in a marked carton, the consumer should have access to that information.
  4. 4 Throw out any eggs that have been refrigerated and then sat out at room temperature for two hours or more. Once an egg has cooled in your refrigerator, it is important to keep it at the same temperature. A cool egg in a warmer environment begins to sweat, which can encourage bacteria to grow on the outside of the egg.
    • To prevent temperature fluctuations, store your eggs in the coldest part of your refrigerator, not on the door. The temperature is more likely to fluctuate on the door when it is opening and closing, which may cause your eggs to sweat.
    • If you receive your eggs unwashed and at room temperature, they do not need to be refrigerated. Many countries, including most European countries, keep their eggs at room temperature. This is safe because eggs are laid with a protective “bloom” which naturally keeps bacteria out. Once the eggs are washed, however, they must be refrigerated. Also, in most European countries, the hens have been inoculated against Salmonella prior to laying their eggs.
  5. 5 Use the packaging guidelines of your country to determine how long to keep your own eggs. If you have egg-laying hens and you’re wondering when they will go bad, you can refer to your country’s guidelines for freshness. It’s a safe bet your eggs will be good for at least two months, if not more.
    • If you’re not sure how long you’ve had your fresh eggs or if you think they are older than two months, learn the signs of bad and old eggs to help you decide whether or not you should use them in your cooking.

If eggs are being consumed by high-risk individuals (the very young or elderly), you may want to only use eggs at their peak freshness. While eggs are generally just fine for weeks after their expiration date, you may want to take extra precautions when feeding those with lowered immune systems and stick to just the freshest eggs.

Advertisement Article Summary X One easy way to tell if an egg is bad is to carefully place it in a large bowl of water. If the egg sinks to the bottom on its side, it’s fresh. If the egg sinks and stands up on one end, it’s not fresh but it’s still safe to eat.
