8 ways to distinguish unhealthy from healthy eggs

distinguish unhealthy from healthy eggs

Today, large egg producers use advanced equipment to distinguish unhealthy from healthy and separate them. On the other hand, using dating machines or industrial jet printers, the production and expiration dates are printed on the eggs so that customers can be sure of their freshness. But the issue of healthy eggs is always of special importance in the minds of consumers.

Eating unhealthy eggs can have dangerous consequences. Poisoning caused by eating rotten eggs is called salmonella. The symptoms of this type of poisoning include diarrhea, stomach pain, fever, and chills. If it occurs in children or people with weak immune systems, they must see a doctor and be treated.

Due to the importance of the topic, we have tried to briefly mention the methods of distinguish unhealthy from healthy.

Simple methods to distinguish unhealthy eggs from healthy ones

1- Print production and expiration date

The first thing to pay attention to when buying eggs is to print the production and expiration dates on the eggs. Production and expiration dates are often written by egg jet printers on eggs that are marketed by reputable producers so that consumers can ensure the freshness of eggs when purchasing. So, as much as possible, it is recommended to avoid buying unlabeled bulk eggs that do not have a production or expiration date.

2- The appearance of the egg skin

When buying eggs, pay attention to the appearance of the eggs and if you see a crack or leakage or a powdery substance around the crack, it is better not to buy that package of eggs and choose another package.

3- rotateing the egg

Place the egg sideways on a flat surface such as a chopstick or a plate and turn it by hand. If the egg starts spinning evenly, we conclude that it is healthy.

Place the egg sideways on a flat surface such as a stick or a plate and roll it by hand. If the egg starts spinning ( rotateing) evenly, we conclude that it is healthy.

4- Shaking the egg

Shake the egg next to your ear. If you hear a sound from it, the egg is old and if no sound is heard; it is healthy. The reason for hearing the sound from inside the egg is the accumulation of moisture and carbon dioxide, which causes the air bag inside the egg to enlarge.

5- Dip the egg

With this method, you can determine the approximate age of the egg. Immerse the egg in a bowl of water. If the egg is placed at the bottom of the container, it is still fresh, but if it is placed at the top of the container, we conclude that the egg is old. But it may still be usable. It is better to check the health of the egg by using other methods.

6- Smelling eggs

Another way to distinguish an unhealthy egg from a healthy one, which is very simple and reliable, is to smell it. If you smell an unpleasant smell from the crack in the eggshell or after breaking it, be sure that the egg is rotten. This unpleasant smell does not disappear even after the egg is cooked.

7- Check of yolk and white

After breaking the egg, pay attention to the appearance of the yolk and white.

If the yolk is round and bulky, and the white is around it, the egg is healthy. Now, if the yolk is spherical but not voluminous, the egg is a little old.

If you see that the yolk and white are mixed together after breaking the egg, or if the white has lost its gelatinous state and has runny like water, you can assume that the egg is old and unhealthy.

Also, the presence of blood streaks around the yolk and white streaks in the white is not a sign of egg failure; But if you see a blood clot inside the egg, avoid consuming it.

8- Exposure to light method

One of the interesting ways to distinguish unhealthy from healthy is the method of exposing or shining light on eggs, which is usually used by egg producers to detect cracks or any defects in eggs. This device, which is called Candling, shows the defective and cracked state of the eggs by shining light on the eggs that are moving on the conveyor.

You can also check the inside of the egg by holding it in front of a light bulb and see a small air bubble at the larger end of the egg. The older the egg is, the larger the air bubble will be, so it is more likely to be unhealthy.

Egg storage

Usually, eggs that are kept in the refrigerator can be used between 3 and 5 weeks after production. In order for the eggs to remain healthy for a longer time, it is better to keep them in the refrigerator as soon as possible after packaging.

Remove the eggs from the refrigerator at least two hours before consumption. In other words, eggs that remain at room temperature for more than two hours after leaving the refrigerator provide the basis for the growth of dangerous bacteria.

Poisoning caused by eating unhealthy eggs

poisoning, which is called salmonella, is a type of infection that causes
symptoms such as fever, abdominal cramps, diarrhea and vomiting. Usually, adult
people whose immune system is in good condition will get rid of the poisoning
caused by eating unhealthy eggs after a few days. But children, the elderly,
and people with weak immune systems may need to prescribe antibiotics.
Therefore, it is recommended to consult a doctor if this problem occurs.

a result, to prevent salmonella poisoning, it is very important to know the
methods of distinguishing unhealthy eggs from healthy ones. In general, special
attention should be paid to the credibility and reputation of the producer, the
existence of production and expiration date on the egg and its storage



We hope that by reading this article, you will have no problem 
distinguish unhealthy from healthy eggs
