Chicken eggs are a nutritious food and are very popular in the daily meals of many families, but not all eggs are of guaranteed quality and safety.

To avoid buying spoiled, poor quality eggs, you need to pay attention to the following signs:

1. Egg shells are cracked, broken or have dirt

Cracked, broken eggs are an ideal environment for bacteria to enter and cause harm to health.

Dirt on the egg shell can be chicken droppings, mold or other dirt, potentially causing disease.

2. See if eggs float

The easiest way to tell if your eggs are still fresh is to see if they sink in water. Simply fill a glass or bowl with cold water and submerge the egg. If it sinks to the bottom and lays flat on its side, it is still fresh.

If the egg sinks, but stands on one end at the bottom of the glass or bowl, the eggs are not as fresh but still edible. An egg that floats to the top is not fresh and could be spoiled. The science behind this is based on the fact that eggshells are semipermeable, which means air can get through. The older the egg, the more air penetrates its shell, causing it to float.

Rotten eggs also release gases that can make them buoyant. If an egg smells bad or you are uncertain if it’s spoiled, the safest bet is to throw it out.

3. Unclear yolk and white

When holding an egg under the light, the yolk of a fresh egg will be in the center, while the white will be clear and solid.

Old, spoiled eggs will have a deviated yolk, thin white and possibly mixed with blood.

4. Unusual fishy smell

Fresh eggs have a characteristic light fishy smell. If the egg has a strong, unpleasant fishy smell, it is likely that it has spoiled.

5. Too old eggs

Fresh chicken eggs are best within 28 days from the date of production.

Old eggs will reduce quality and can be harmful to health.

6. In addition, you should also note

– Buy eggs from reputable places with clear origins.

– Check the expiration date carefully before buying.

– Store eggs at cool temperatures, away from direct sunlight.

By paying attention to the above signs, you can choose fresh, delicious eggs, ensuring the health of your whole family.
