A bad egg looks slimy, cracked, or powdery on the outside; inside, it has pink, iridescent, or greenish whites/yolk, a flattened yolk, watery whites, or a strong sulfuric smell, often accompanied by a watery slosh when shaken. A fresh egg's yolk sits high and thick, while a bad one's whites are thin and spread out.
To tell if an egg is bad, use the float test: fresh eggs sink, older ones stand on end, and rotten ones float, but the most reliable method is the smell and visual test after cracking it in a separate bowl—a sulfurous odor, discoloration (pink, green, iridescent), or a very flat, runny consistency means it's bad, even if it passes the float test.
Nausea, vomiting, diarrhea, and dehydration are common concerns after eating spoiled eggs. Eating spoiled eggs can cause food poisoning with symptoms like stomach cramps, nausea, vomiting, and diarrhea. Most cases improve with rest and hydration at home. Drink plenty of fluids to prevent dehydration.
If the yolk is watery or gray, the egg is likely rotten. A slimy or chalky shell can indicate bacteria or mold growth, while a brown shell is a sign of spoilage. If any of these signs are present, toss the egg to be safe.
Carefully lower your eggs into fresh cold water using a spoon (you can do this in the pan if you're about to boil them). If the eggs stay at the bottom they're fresh; if the eggs float, however, they're stale and best avoided.
How long do eggs last in the fridge? The general consensus on food safety from the USDA is that raw eggs in the shell will last for three to five weeks when properly refrigerated.
The "555 egg method" is a popular technique for making easy-peel hard-boiled eggs in an Instant Pot or other pressure cooker, involving 5 minutes of high pressure, a 5-minute natural pressure release, and a final 5-minute ice bath to stop cooking and loosen the shell, though results can vary, with some finding it perfect and others needing adjustments.
If you catch a whiff of anything sour or foul, it's a clear sign that the egg has gone bad and should not be used. Before you crack them open, inspect your eggs for any signs of dirt, cracks, or unusual discoloration. A clean, intact shell is a good indicator of a fresh egg.
No, the egg float test isn't completely accurate for determining if an egg is truly bad (rotten), though it generally indicates freshness or age; a floating egg is usually old and should be tossed, while a sinking one is likely fresh, but a fresh egg can sometimes float, and an old one can still sink, so the sniff test after cracking remains the most reliable way to check for spoilage.
Most people infected with Salmonella develop diarrhea, fever, abdominal cramps, and vomiting 12 to 72 hours after infection. Symptoms usually last 4 to 7 days and most people get better without treatment. However, in some people, the diarrhea may be so severe that they need to be hospitalized.
Symptoms usually begin 6 hours to 6 days after infection and last 4 to 7 days. Most people recover without antibiotic treatment. Antibiotics are needed only for patients who are very ill or at risk of becoming very ill.
Unlike good eggs that have simply gone bad, an egg infected with salmonella won't smell bad. Symptoms of salmonella poisoning include vomiting, fever, diarrhea, and stomach cramps.
As eggs age, the whites and yolks lose some of their firmness and structure. It's not uncommon for expired or nearly expired eggs to seem somewhat watery when you crack them open, but if the egg is well within its best by date, wateriness can be a sign of spoilage.
Risks of Eating Bad Eggs
As eggs go bad, they develop other types of bacteria like E. Coli that lead to severe illness. If an egg is bad, symptoms of illness appear within six to 48 hours and may include: Diarrhea.
"Infected chickens are often asymptomatic, which is why food-safety experts raise so many caveats about consuming raw eggs in any form," he said. "However, cooking your eggs thoroughly will kill the Salmonella, so you can eat eggs with no concern."
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.
Egg Freshness Float Test
This is not a myth; fresh eggs sink while bad eggs float to the top. Simply fill a bowl with cold tap water and place your eggs in it. If they sink to the bottom and lie flat on one side, they are fresh and good to eat.
Key Takeaways. As long as they have been refrigerated at 40°F or below, expired eggs are safe to eat past the "best by" date on the carton. Generally you can keep eggs three to five weeks from the day you put them in the refrigerator. Discard any eggs that are cracked and have an off-odor.
To tell if an egg is bad, use the float test: fresh eggs sink, older ones stand on end, and rotten ones float, but the most reliable method is the smell and visual test after cracking it in a separate bowl—a sulfurous odor, discoloration (pink, green, iridescent), or a very flat, runny consistency means it's bad, even if it passes the float test.
Washing eggs allows bacteria to move from the outside of the shell to inside the egg. Never wash eggs and throw away all dirty eggs. Salmonella is the most commonly reported bacteria responsible for foodborne illness outbreaks and is usually associated with eggs and egg products.
More research is needed to figure out the link between eggs, diabetes and heart disease. Health experts now suggest eating as little dietary cholesterol as you can, aiming to keep intake under 300 milligrams (mg) a day. One large egg has about 186 mg of cholesterol — all of which is found in the yolk.
You can boil eggs in either cold or hot water, but starting in cold water is often recommended for easier peeling and to prevent cracking by allowing gradual heating, while adding eggs to already boiling water gives more precise timing but requires care to avoid shocking them. For consistent results, especially hard-boiled, many sources suggest starting in cold water and bringing to a boil before cooking for a specific time, then shocking in ice water.

The Best Way to Peel Boiled Eggs
I mean, let them sit in that ice bath for at least 15 minutes, or, better yet, let them sit overnight in the fridge. The cooler the egg is, the firmer and tighter its structure will be, and the less likely it will be to develop craters when you pry off the shell.
