What are Grey Eggs?
A chemical interaction between sulfur in the egg white and iron in the yolk may cause even perfectly hard-boiled eggs to become greenish-grey around the yolk. At the surface of the yolk, the two chemicals mix to form ferrous sulfide. Although the color shift may be unpleasant, it is not dangerous and is safe to consume.
This occurs inside the ovalbumin at 77 degrees Celsius. Above 70 degrees Celsius, the sulfur in the egg whites produces hydrogen sulfide, which interacts with the iron to make iron sulfide, giving it a greenish gray appearance. You may halt the cooking process by running the cooked eggs under cold water to bring them to room temperature.
How Do You Boil Grey Yolk Eggs?
Iron sulfide in the egg forms gray or green rings around the egg and is frequently released as a result of overcooking. The dry and crumbly yolk will firm in about 14 minutes under boiling water, according to the American Egg Board. To prevent overcooking your grey eggs, immerse them all in an ice bath as soon as they are done.
When hardboiled eggs are overdone, a ring forms around the yolk. To guarantee that your grey eggs, or fresh eggs, peel easily, gently lay them in boiling water for eight to ten minutes to shrink the albumen, then turn off the heat and cover them. Next, put the huge eggs into ice-cold water to further reduce the albumen and prepare to peel them.
If the egg yolks are overcooked, they will develop a greyish green color.
How to Know if You Have a Bad Egg
Fill a dish with cold water and place your eggs in it to see whether you have a bad egg. The eggs are fresh and safe to eat if they settle to the bottom of the dish and are placed flat on their side. Because of the large air cell that develops at the base, bad eggs will rise to the surface. Floating eggs should not be ingested and should be thrown of promptly.
Grey eggs that remain in the bottom of the dish but stand on one end indicate that they are not as fresh as they might be but are still safe to eat. Hard-boiled eggs, on the other hand, are more difficult to assess, so if you are unsure about their quality, do a sniff test. If the fragrance is off, the egg has likely gone bad or is about to go bad. This test may be performed on both cooked and raw eggs.
Why Do I Have a Dark Egg Yolk?
The color of the yolk is influenced by the diet of the hen that laid the egg; hens given yellow-orange pigmented food will frequently produce eggs with darker yolks. While artificial coloring is not permitted in chicken feed, some farmers would add marigold petals with feed to color the yolks orange. Yet, the color of the yolk has nothing to do with nutritional value and is instead determined by the pigments found in chicken feed.
When hens consume a lot of xanthophylls (yellow-orange pigments), their egg yolks become deeper orange. Darker yolks may be the consequence of greater Omega 3 levels in the hen’s diet, but there isn’t much of a difference other than how it looks on your dish. Also, the color of the yolk does not change in older eggs, thus an egg with a dark yolk is still safe to consume.
Are Dark Yolks Better?
Darker egg yolks from pasture-raised chickens are more likely to contain trace levels of fat-soluble vitamins. They might have been consumed as a consequence of a diet consisting of earthworms and beetles foraged from grass. The color of the yolk has no influence on the nutritional content of the egg, according to study conducted by the United States Department of Agriculture.
Each yolk has more fat, less water, and less than half the protein found in egg whites. Moreover, the color of an eggshell has no bearing on its nutritional content, and there is no difference between brown and white egg shells. The color of the egg is determined by the breed of the hen who laid it.
What Color is a Healthy Yolk?
In general, you want your yolk to be bright yet black. Such yolks are often generated by chickens kept in meadows and fed worms, fresh grass, and grasshoppers. This kind of diet will be high in carotenoids, which provide the orange hue.
You would be shocked if you came across an egg with a white yolk. The good news is that they are completely safe to consume and will not taste any different. This hue might range from light yellow to pale yellow to entirely white.
If you observe any odd symptoms of discoloration outside of the yolk, such as iridescent, pink, or greenish egg white or yolk, reject these grey eggs right once. According to the USDA, eggs with a greenish-gray ring around a hard-cooked egg yolk are still safe to consume.
Can You Get Sick from Bad Eggs?
Grey eggs infected with salmonella may cause food poisoning with a variety of symptoms that typically show six hours to six days after eating the faulty egg. Moreover, ingesting food infected with dangerous germs might result in foodborne disease one to three days later. Salmonella food poisoning symptoms may include diarrhea and fever.
If a rotten egg is not handled and cooked correctly, it might still make you sick. This is due to the fact that eggs may still be infected with salmonella or e.coli even when cooked at high heat in a cast iron pan.
Are Eggs Safe in the Fridge?
Eggs may be refrigerated for up to five weeks from the day they were put in the fridge. When you notice the sell-by date on the carton, it typically refers to how long the eggs will be completely fresh and safe to use. To guarantee that you consume excellent eggs, buy your eggs before the expiry date or sell-by date.
Don’t Be Afraid of Grey Egg Yolk
Keep in mind that the color of the yolk does not reflect freshness, although egg whites might become more watery and loose with time. Despite yet, yolks will not normally lose their color if stored in the refrigerator. The next time you prepare eggs, remember that their color is unimportant as long as they don’t have other indicators of deterioration, such as green spots.

FAQs
What does it mean if an egg is grey?
So, what’s the deal with the unpleasant discoloration? Hard boiled eggs may develop that greenish gray hue around the exterior of the yolk due to a chemical interaction between the iron in the yolk and the sulfur in the white.
Why do eggs go grey in the fridge?
Refrigerating cooked eggs for a week will not cause them to become gray. Instead, at temperatures of 170F or above, the iron in the yolk reacts with the sulfur in the albumen to form ferrous sulfide.
What color is an unhealthy egg?
Cracking an egg open into a bowl is the easiest technique to see whether it is ruined. If the egg white is pink or iridescent, this indicates Pseudomonas bacteria deterioration. When certain of these bacteria are ingested, they may make humans sick and emit a greenish, fluorescent, water-soluble hue.
Is it safe to eat a discolored egg yolk?
They should throw out eggs with strange discolorations, such as a pink, iridescent, or greenish egg white or yolk. According to the USDA, eggs with a green ring on the hard-cooked yolk after frying are safe to consume.
Why did my chicken lay a grey egg?
Heavy bloom hens may lay grey eggs (green + heavy bloom) or lavender eggs (light brown + heavy bloom). The most beautiful olive eggs with a rich bloom are entirely gray in real life, with the dark green below completely hidden by the white overlay bloom.
Is it ok to eat grey egg yolk reddit?
The brownish ring around a hardboiled egg is caused by an interaction between the iron in the yolk and the sulfur in the white, resulting in ferrous sulfide. Although it is a symptom of an overdone egg and is not very appealing, it is completely harmless.
What are signs that eggs have gone bad?
Fill a basin halfway with cold tap water and lay your eggs in it. They are fresh and edible if they drop to the bottom and lie flat on one side. Because of the enormous air cell that develops at its base, a poor egg will float. Any drifting eggs should be discarded.
How can I tell if eggs have gone bad?
Cracking open your eggs is the most accurate technique to determine if they have gone rotten. If the yolk or white is discolored, the egg is bad. Bacterial growth is indicated by discoloration. If your eggs seem to be OK but have an odd or sulfuric odor, they are rotten.
Can you eat grey scrambled eggs?
It doesn’t take long for cooked eggs to become green. And, although it isn’t poisonous or has any discernible flavor, it does seem unappealing. To avoid this, most breakfast buffets add a little lemon juice and cream to their scrambled eggs.
Can you tell if an egg is bad without breaking it?
The float test is the simplest way to detect a bad or old egg before splitting it open. In a glass of water, place the egg. Healthy eggs descend to the bottom, but rotten eggs float.
