How To Tell If Eggs Are Bad-Everyone has had the problem reaching into the refrigerator for an egg but forgetting how long they have been sitting there. It is true that when the air pocket within becomes wider and the whites get thinner, the quality of an egg starts to deteriorate over time. An egg, however, only “goes bad” when it begins to deteriorate due to mold or bacteria. In actuality, your eggs can still be edible for many more weeks. When in doubt, you may use various techniques on how to tell if eggs are okay or rotten. 

How To Tell If Eggs Are Bad

Check the Packing Date, Not the Expiration or Sell-by Dates

How To Tell If Eggs Are Bad

The packing date, not the expiry or sell-by date, is the most trustworthy date on your egg carton. The sell-by date is a technique used by retailers to determine how long a product should be kept on the shelf, and the expiry date provides a basic indicator regarding how fresh your eggs are. Both won’t provide you with a specific age estimate for your eggs.

On the other hand, the packing date indicates the precise day your eggs were placed in the carton. Eggs should be safe to consume within four to five weeks after the pack date and two to three weeks after the expiry date. The Institute of Agriculture and Natural Resources at the University of Nebraska-Lincoln advises eating your eggs three to five weeks from the day you bought them if you’re not into understanding dates and codes on cartons.

Do A Sniff Test

How To Tell If Eggs Are Bad

The smell test is the oldest, most straightforward, and most accurate technique for determining if an egg has gone rotten. If you discover that your eggs are over their “sell by” or expiry date, all it takes is a quick whiff to determine whether they are still edible.

Whether cooked or uncooked, eggs that have gone rotten will have a distinct odor. If you cannot determine the egg’s contents while still in its shell, break it open and take a whiff. Toss the egg and wash the dish or plate in hot, soapy water before using it again if anything smells off. The egg is still safe to use if everything smells normal or if there is no odor.

Conduct A float test

A float test will be the best option if you don’t want to bother looking up and calculating the date (or doing the arithmetic). Because eggshells are permeable and air may readily pass through them, the older the egg, the more air there is within. The egg will eventually have enough air within it to allow it to float after enough time has passed.

Fill a bowl or cup with water to perform a float test (it should be big enough to submerge your egg fully). By carefully placing it inside, check to see whether your egg floats or sinks. It’s bad; if it floats, you should throw it away. Before choosing whether to use or reject the egg, crack it into a basin and look at it to check for an odd smell or sight. You can smell rotten eggs when you crack open their shells, whether cooked or uncooked.” The egg is not remarkably fresh but is still safe to eat if it dips and stands up. The egg is at its best if it dips and tilts to one side.

Use Your Eyes

How To Tell If Eggs Are Bad

While it’s still in the shell, examine your egg. It is most likely infected by bacteria or mold if it has cracks or a slimy or powdery appearance. You should check the yolk and egg white after the egg has been broken onto a level surface before using it to produce that cheese scramble. Fresh eggs have an egg white that is somewhat firm and stands up around the yolk, with a brilliant yellow or orange yolk. A less-fresh egg will have a more spread-out, flat white.

Candle Your Eggs

How To Tell If Eggs Are Bad

A candling technique is used to evaluate the quality of a table egg or the chick’s growth within a fertilized egg. Before table eggs are packed, this is carried out industrially using specialized equipment to assure accurate grading. However, if you’re ready to learn, you can also do it on your eggs at home.

You’ll need a modest, bright light source and a dark space. Place the light source close to the egg’s big end. After that, swiftly rotate the egg from left to right while tilting it. If done properly, the egg’s contents ought to be lighted. This enables you to determine the size of the egg’s air cell. The air cell in a very new egg shouldn’t be any narrower than 1/8 inch, or 3.175 mm. The air pocket will grow as the egg matures as gasses replace the water lost via evaporation.

The firmness of the egg’s white and yolk should also be discernible by tilting the egg from side to side. A fresher egg is indicated by less movement. Although it can take some expertise, candling accurately enables you to determine whether an egg is fresh or old. However, it cannot determine if an egg has gone rotten, much as the float test.

Shake It

Holding an egg up to your ear and shaking it is another technique. However, it’s not as effective as the float trick. It’s spoiled if you hear liquid sloshing around within. However, silence indicates positive news. A wet, swirling yolk is often the cause of the sound.

Understanding Egg Color

You’re accustomed to seeing an egg with a clear egg white and a yellow yolk. While certain color combinations are safe, some are not:

Red Spot On The Yolk

A red spot on the yolk, often known as a blood spot, appears when a chicken ovulates and produces the yolk. When a blood artery near the yolk breaks, it leaves a crimson mark. It’s okay to eat eggs with a red spot.

Cloudy Egg White

Cloudiness signifies how recently the egg was laid. When the egg is deposited, cloudiness is brought on by high carbon dioxide levels. It becomes less cloudy with time. It’s okay to consume these eggs.

White Strings In The Egg White

Chalazae is another name for white threads in the egg white. It maintains the egg yolk’s position above the egg white. The egg is likely to be quite fresh if the white lines are more noticeable. Before cooking, white threads don’t need to be taken out.

Brighter Or Darker Yolk 

A hen’s diet influences the hue of the yolk in the eggs she produces. The yolk appears paler when chickens are fed wheat and barley. The yolk is darker when a hen is fed grain and green vegetables. Wheat and barley-fed hens lay eggs with lighter-colored yolks. Green plants, maize, and alfalfa are given to hens to produce eggs with darker yolks. The color of the yolk does not indicate the freshness or health of the mother hen.

The Green Ring Around The Cooked Yolk

If you hard boil an egg in the shell, the yolk may overcook and become green. The heat causes sulfur and iron to react, giving the yolk a faint shade of green. It’s still okay to consume eggs. ‌

Egg White That Isn’t White

If the egg white isn’t crystal clear or white with a little cloudiness, it can be rotten. Your egg white can contain dangerous bacteria if it appears green or iridescent. It may not be advisable to eat it. Check your egg’s odor if the color seems odd. Throwing away eggs that could be contaminated is always a good idea to err on the side of caution.

How To Properly Store Eggs

As long as they are correctly stored in the refrigerator, eggs have a long shelf life. Place your eggs on the coldest shelf, which is often in the center or bottom of your refrigerator, rather than the inside of the door. Since it is constantly exposed to the outside air when you open your refrigerator door, the door is the section that gets the hottest.

Eggs should remain in their carton. The carton shields the eggs from cracking, which also absorbs extra air and insulates them. Keeping your refrigerator at 45°F or below is advisable to ensure that your eggs survive as long as possible. 

Frequently Asked Questions

Can You Get Sick From Eating Expired Eggs?

Yes, you can. Salmonella infection, which may cause fever, vomiting, and diarrhea, is the greatest danger associated with consuming rotten eggs.

Why Would A Chicken Lay A Tiny Egg?

They happen as a result of the reproductive system’s incomplete development. While some pullets may lay an ideal egg on their first attempt, small eggs are common in chickens just beginning to lay. Any age of hens may lay little eggs if their reproductive system is “upset.”

How Do You Know When Eggs Are Bad?

Put your eggs in a basin and fill it with cold tap water. They are fresh and suitable for consumption if they settle to the bottom and lie flat on one side. The big air cell that develops at the base of a damaged egg causes it to float. Throw away any eggs that are floating.

Why Do Chefs Use Brown Eggs Instead Of White?

The main factor affecting flavor is freshness, and brown eggs may sometimes be more so given their propensity to originate from local farms and arrive at your grocery promptly. There is hardly any nutritional difference, however.

Can I Eat A Tilting Egg?

An egg is considered extremely fresh if it dips to the bottom of a bowl of water and rests sideways; if it stands on one end at the bottom of the bowl, it is considered less fresh but still fine to eat. However, if it rises to the top of the water, a sign that air has gotten into the shell, it is no longer fresh.
