Eggs are a healthy source of protein and other essential nutrients. Although the eggs are properly stored, have a decent shelf life, they can end up spoiling. Many families have a habit of keeping eggs in the refrigerator for a long time. Over time, the quality of the egg may decline, due to the larger internal air bags and thinner the whites. Due to the outer shell, it is difficult to tell whether the egg is fresh or damaged if only seen with the naked eye. How to tell if eggs are bad or good?
Eggs are a food that has many healthy nutrients. It is often preserved so that they can be used for a certain period of time, in accordance with the daily menu of each family meal. However, we do not always know if an egg is fresh or broken if we only see with the naked eye. Even if eggs are stored in the refrigerator after a while, we need to check the freshness of eggs before use to avoid eating spoiled eggs.
There is a simple way, for example, when shaking an egg, if the yolk hits an egg, the egg is still fresh and can be eaten.
Eggs bought sometimes forget to eat for a long time, so spoiling is common. However, the problem is that sometimes you can’t tell which eggs are spoiled to throw away and which are still edible. If you eat all of it, it is not good for your health, otherwise if you throw it out, it will be a waste. Hence, we will show you how to tell if eggs are bad or good in the following ways:
Visual Check for Bad or Good Eggs
It is difficult to recognize a damaged egg when seen with the naked eye. However, a bad egg will have some of the following obvious signs to help you know you can’t use it:
- There is a crack in the eggshell.
- There is powder on the eggshell.
- The eggshell looks or feels messy.
Eggs with cracked or viscous shells can be contaminated with bacteria, while the powder on the shell can be a sign of mold. Eggs should be discarded with any unusual discoloration on the inside, such as pink, iridescent, or the whites or the yolks fall green.
However, eggs that show a green ring on a well-cooked yolk after boiling are safe to eat, according to the US Department of Agriculture (USDA). Green is often the result of overcooking or the high iron content in broth, according to Medicine News Line.
Looser whites or yolks than usual can also indicate an outdated egg. If the eggs do not smell strange you can still use them.
Check the Egg’s Shelf life to See if it’s Good or Bad
Every dozen eggs or egg baskets you buy from the supermarket have the date of packing. You need to pay attention to this timeline before buying and before using it to see if the egg is safe or not.
According to the FDA (US Food and Drug Administration), eggs can be stored for 4-5 weeks after being packaged. However, these numbers can fluctuate based on how they are stored and the temperature. Leaving the eggs in the refrigerator will help preserve them for a longer time. However, you should not remove the eggs from the refrigerator and leave it at room temperature for more than 2 hours. Because then it will increase the risk of developing bacteria.
If you are harvesting the eggs at home, keep in mind that the day the birds lay eggs. This time is the milestone to calculate the shelf life of the eggs. Usually eggs have a shelf life of 4 weeks, from the 3rd week onwards and should not be eaten anymore. The reason is that at this time the eggs begin to decompose, nutrients change into toxins, which are not good for health. Be especially cautious when eating eggs from week 6 on.
The best way to store eggs is to keep them in trays or boxes in a cool, dry place. The eggs should be of good quality midway through the first 3 weeks after laying.
However, some eggs that are more than 30 days old from the date of packaging are still usable. The eggs can still be used if you preserve them well, but the nutritional content will be reduced. You should still cook the eggs to avoid the invasion of bacteria.
The main risk of eating spoiled eggs is Salmonella infection. This type of bacteria causes intestinal infection, usually found in poultry. Salmonella can grow both on the shell and inside the egg yolks and egg whites. Infection with this bacterium will cause food poisoning. Symptoms include diarrhea, stomach cramps, fever, and vomiting.
Break the Eggs into a Bowl to See if They are Bad or Good
If you look at the appearance of the egg and can’t tell whether it’s good or bad. The fastest way is to directly break it into the bowl to check it out. Here’s an easy way to check for fresh or damaged eggs. After breaking the raw egg into a bowl or plate. If the egg whites and egg yolks are not grouted, mixed together, the 2 yolks are still intact and separate means fresh eggs.
Make sure the eggs are fresh when you don’t fully trust them. Use a pair of chopsticks to try the egg yolk. If the egg is left for a long time, it is difficult to pick up and the yolk is also easily broken. If the egg is fresh, you will pick it up very easily and the yolk is also very firm, elastic, so it is difficult to break.
A simpler little test trick is to use a few toothpicks to pin the egg yolks. Eggs that have an upright toothpick are fresh eggs. Any eggs that have just been pinned to the toothpick that cannot stand are that the eggs can no longer be eaten. Now you can confidently use eggs in your dish.
On the other hand, if you see the whites and yolks spreading over the entire plate, and the yolk is grouted, then the egg is spoiled and should not be eaten. Dispose of spoiled eggs immediately to avoid contagious other eggs and growth of bacteria.
Put the Eggs in the Water to Check if They are Bad or Good
If you want to tell the difference between the bad and the good eggs from the bulk, it can be difficult to examine each egg. It will take you a lot of time. However, the method of dropping eggs in water will help you know which fruit is bad, which is good quickly.
For this test, prepare a cup of water or a water bottle to put the eggs in. If the eggs quickly sink and lie at the bottom of the cup horizontally, the eggs are still fresh, you can safely use them.
If the egg slowly sinks and lies vertically or diagonally, the egg is not fresh and should be used immediately. If the eggs do not sink to the bottom, instead float in the center of the cup or float to the surface of the water, this is a sign that the eggs are spoiled and should not be eaten.
Floating eggs are caused by gas generated from organic matter in the decomposition process located inside the egg. The degree of floating eggs refers to the degree of decomposition and metamorphosis should not be eaten.
However, some eggs are floating but still usable or some sink eggs are damaged. This method will still have a few flaws so you should check it again.
Screen Your Eggs with a Flashlight
Flashlight is a method used to evaluate the quality of an egg or to evaluate the development of chicks and ducklings in the egg.
This process is industrially performed using specialized equipment to ensure proper egg grading prior to packaging. However, you can still perform this method at home using a flashlight and staying in a dark space.
During the test, you should keep the source at the larger end of the egg for maximum visibility. Then, tilt the egg and flip it from left to right. The flashlight’s light will illuminate everything inside the egg. Because it was in a dark space, the illuminated egg was even more obvious. You can see the air bags inside the egg to tell if the egg is bad or good.
The egg airbag will help you see if the egg is new or old. When the egg is fresh, the airbag will be around 3,175mm thin. But as the eggs age and age, the amount of water in the eggs lost to the airbag becomes larger. Thanks to this feature you will know exactly whether the egg is bad or good.
Smell the Egg to Tell if it’s Good or Bad
Needless to say, besides some special foods like cheese or some special dishes, most good foods will not smell bad. Eggs are a prime example. A new egg will not have any strange smell at all. We can tell whether an egg is bad or not by smelling it.
Any broken egg will have an unmistakable odor. Its odor can even penetrate the eggshell or last for a long time. You can break the eggs onto the dishes to smell them. If there are any strange odors, throw them away and wash dishes immediately. If eggs do not have a strange odor and the color is consistent, you can use them right away.
If you buy industrial eggs, keep them in the box and keep them in the refrigerator. Because the box will help prevent the egg from aromas from other foods in the refrigerator.
If you are harvesting eggs from the poultry you keep, do not wash them and then put them in the refrigerator. Because the eggshell has a natural coating that protects them from bacteria. If you wash it off, the inside of the egg will become more susceptible to infection and grout. Eggs will maintain good quality within the first 3 weeks after eggs are laid.
Eggs are a very nutritious food that can provide you with a lot of beneficial substances. However, you must store them very carefully and use them while still in good condition. Using spoiled eggs will do a lot of bad things for your health. This article we have shared with you how to tell if eggs are bad or good. Hope it is useful to you!
