How do you know if eggs are good?

Although properly stored eggs have a decent shelf life, they can eventually spoil. However, there are several easy ways to check if an egg is still edible.

Eggs are a good source of protein and other important nutrients. In this article, we’ll look at some easy ways to tell if an egg is edible or not. We also address the issue of egg shelf life, the need to refrigerate them, and the health risks of eating a spoiled egg.

swim test

The float test is a quick and easy way to check an egg’s freshness. Although it does not determine whether an egg has turned, it does provide a useful clue as to an egg’s age. To perform the swim test, place the egg in a large bowl of water. If it sinks or stays on the bottom, it’s still fresh. An older egg stands on its end or swims. The swim test works because as the egg ages, air builds up inside the egg, increasing its buoyancy.

However, a floating egg is still safe to eat. You can also test the egg by opening it, smelling it, and examining it for any visible signs of contamination.

smell test

One of the easiest and most reliable ways to tell if an egg has turned is to smell it. A spoiled egg releases a foul odor when the shell is opened. This smell is also present when someone has already cooked the egg. In some cases, when an egg is very old or rotten, you can smell the rotten odor before opening it. It is wise to discard any eggs that give off a putrid or unpleasant odor. Because this test is very reliable, it’s good to sniff each egg before using it.

Visual inspection

Sometimes an egg looks or feels abnormal, so look out for signs of contamination or rot.

Eggs with any of the following characteristics should be discarded:

– Cracks in the shell
– a powdery substance on the shell
– a shell with a viscous appearance or texture

Eggs with a cracked or slimy shell can be contaminated with bacteria, while a powdery substance on the shell can indicate mold.

If the shell is intact with no obvious signs of damage, contamination or a foul smell, a second visual inspection should be performed after the egg has been opened. Eggs with an unusual interior color, such as B. pink, iridescent or greenish egg white or yolk should be discarded.

However, eggs that develop a green ring on the hard yolk after cooking are safe to eat. The green color is often caused by overcooking or high iron levels in the cooking water. A thinner egg white or yolk than usual doesn’t necessarily mean it’s unsafe to eat, it can affect its flavor and cooking properties. A quick visual inspection of the eggs in the carton is recommended before purchasing. If one is torn or leaking, choose a different package.

expiry dates

People who keep eggs in their original packaging can also check the expiration date to determine if it’s still safe to eat.

How long do eggs stay fresh?

Eggs can be stored in the refrigerator for 3 to 5 weeks. Although the expiration date expires during this period, they are still safe to consume. To keep them safe, place them in the fridge right after you buy them. The fridge temperature should be 4°C and the eggs should be placed in the coldest part of the fridge and not in the door.

Refrigerated eggs stay fresh 3-5 weeks after the pack date on the carton.

Should Eggs Be Stored in the Fridge?

Chilling eggs as quickly as possible helps preserve their freshness and reduces the risk of salmonella contamination. Eggs should not be refrigerated at room temperature for more than two hours. Cold eggs can sweat when heated, which can increase the risk of bacterial growth.

Health risks associated with eating a spoiled egg

If a person eats raw eggs, they are at risk of contracting salmonella, a form of food poisoning. Salmonella are bacteria that can grow on the shell as well as in the yolk and egg white.

Symptoms of a salmonella infection can include:

Diarrhea
Stomach cramps
Fever
Vomit

Symptoms usually develop 6 hours to 6 days after eating a contaminated egg and last about 4 to 7 days. Most people recover from a salmonella infection without antibiotics. However, people with severe symptoms may need to be hospitalized.

Salmonella infection is often more serious and dangerous in certain groups of people, including the following:

Adults over 65
Children under 5 years old
People with a weakened immune system, such as B. People who have had an organ transplant or are living with HIV.
Not all people who eat a spoiled egg will develop a salmonella infection.

Measures to reduce the risk of salmonella include:

– Wash your hands and all objects that have come into contact with raw eggs
– Store the eggs in the fridge
– Throw away eggs past the expiration date
– Boil the eggs thoroughly so that the yolk and white are firm

Continue

When eggs spoil, they start to smell bad, and the yolks and whites can become discolored. Cracked or slimy eggshells can also be a sign of bacterial contamination.

An easy way to determine an egg’s freshness is to check the expiration date, visually inspect its shell, and crack it open to smell the inside. If a person has any doubts that an egg has been tampered with, they should discard it. The main risk from eating spoiled eggs is salmonella infection, which can cause diarrhea, vomiting, and fever. The risk of salmonellosis can be reduced by storing eggs in the refrigerator, discarding eggs with cracked shells, and thoroughly cooking them before eating.
