How to know if the eggs are good

Although properly preserved eggs have a decent shelf life, they can end up spoiling. There are, however, several simple means of verification and an egg is still good to eat.

Eggs are a good source of protein and other essential nutrients. In this article, we look at some simple ways to know whether an egg is good to eat or not. We also address the issue of egg shelf life, the need for refrigeration, and the health risks associated with eating a spoiled egg.

Flotation test

The float test is a quick and easy way to check the freshness of an egg. Although it does not determine if an egg has turned, it does provide a useful indication of an egg’s age. To test the float, place the egg in a large bowl of water. If it leaks or stays at the bottom, it is still fresh. An older egg will stand on its end or float. The flotation test works because air accumulates inside the egg as it ages, which increases its buoyancy.

However, a floating egg can still be eaten safely. The egg can also be tested by opening it to smell it and verifying that it has no visible signs of contamination.

The olfactory test

One of the easiest and most reliable ways to find out if an egg has turned is to feel it. A spoiled egg gives off a foul odor when you open the shell. This odor will be present even if someone has already cooked the egg. In some cases, when an egg is very old or rotten, you can smell it before opening it. It is advisable to throw away any eggs that give off a foul or unpleasant odor. As this test is very reliable, it is good to smell each egg before using it.

Visual inspection

Sometimes an egg has an abnormal appearance or sensation, so look for signs of contamination or rot.

Eggs with one of the following characteristics must be discarded:

– cracks in the shell
– a powdery substance on the shell
– a shell of viscous appearance or texture

Les œufs dont la coquille is fissurée or visqueuse can be contaminated by bacteria, while a poudreuse substance on the shell can be a sign of moisture.

If the shell is intact and shows no obvious signs of damage, contamination or odor, a second visual inspection should be performed after opening the egg. eggs whose inside is unusually colored, such as a white or yellow, pink, iridescent or greenish egg yolk, should be discarded.

However, eggs that develop a green ring on the hard yellow after cooking can be eaten safely. The green color is often due to overcooking or high iron content in the cooking water. A whiter or egg yolk that is more liquid than usual does not necessarily mean that it is dangerous to consume, it can affect its taste and cooking properties. Before buying, it is advisable to carry out a quick visual examination of the eggs in the carton. If one of them is cracked or leaking, choose another package.

Expiration date

Persons who keep the eggs in their home box can also check the expiry date to see if they are still suitable for consumption.

How long do the eggs stay fresh?

The eggs can be stored in the refrigerator for 3 to 5 weeks. Even if the expiration date expires during this period, they can be consumed safely. To keep them safe, they must be placed in the refrigerator immediately after purchase. The temperature of the refrigerator should be 4 ° C, and eggs should be placed in the coldest part of the refrigerator rather than in the door.

The refrigerated eggs remain fresh for 3 to 5 weeks after the date of packaging on the carton.

Should eggs be stored in the refrigerator?

Refrigerate the eggs as soon as possible, keep them fresh and reduce the risk of salmonella contamination. Eggs should not be left refrigerated at room temperature for more than two hours. Cold eggs can sweat as they warm up, which can increase the risk of bacterial growth.

Health risks associated with the consumption of a damaged egg

If a person eats raw eggs, they may develop a Salmonella infection, a form of food poisoning. Salmonella is a type of bacterium that can grow both on the shell and inside the yolk and egg white.

Symptoms of Salmonella infection may include:

diarrhea
abdominal cramps
fever
vomiting

Symptoms usually develop 6 hours to 6 days after eating a contaminated egg and around 4 to 7 days. Most people get a Salmonella infection without antibiotics. However, people who have symptoms of graves may need to be hospitalized.

Salmonella infection is often more severe and more dangerous in certain groups of people, not below:

adults over 65 years of age
children under 5 years
people whose immune systems are weakened, such as those who have had an organ transplant or are living with HIV.
People who eat a damaged egg do not develop all Salmonella infections.

Measures to reduce the risk of Salmonella include:

– wash your hands and any objects that have come in contact with raw eggs
– keep the eggs in the fridge
– lay eggs after their expiry date
– Cook the eggs thoroughly so that the yolks and whites are firm

Resume

When eggs spoil, they begin to smell bad, and the yolk and egg white may fade. Cracked or viscous eggshells may also be a sign of bacterial contamination.

To easily determine the freshness of an egg, simply check the expiration date, visually inspect its shell and the egg to feel the inside. If a person has any doubt about the alteration of an egg, they should throw it away. The main risks of eating damaged eggs are Salmonella infection, which can cause diarrhea, vomiting and fever. The risk of salmonellosis can be reduced by storing eggs in the refrigerator, throwing away those with cracked shells, and cooking them well before eating.
