Eggs are a versatile and nutritious food that can be enjoyed in many different ways. However, it is important to be able to tell if an egg is bad before consuming it, as eating a bad egg can lead to food poisoning.
There are several ways to tell if an egg is bad. One way is to check the expiration date. Eggs should be refrigerated and consumed within 45 days of the date they were laid. If an egg has an expiration date that has passed, it should be discarded.
In addition to checking the expiration date, there are several other ways to tell if an egg is bad. These include checking for cracks or leaks in the shell, floating eggs in water, and smelling the egg.
How to Tell If an Egg Is Bad
Here are 8 important points to help you determine if an egg is bad:
- Check expiration date
- Inspect shell for cracks
- Float egg in water
- Smell the egg
- Look for discoloration
- Check for mold or bacteria
- Trust your instincts
- When in doubt, throw it out
By following these simple tips, you can help ensure that you are only consuming fresh and safe eggs.
Check Expiration Date
One of the most important things you can do to tell if an egg is bad is to check the expiration date. Eggs should be refrigerated and consumed within 45 days of the date they were laid. This date is typically stamped on the carton or on each individual egg.
- Look for a Freshness Code
In the United States, eggs are required to have a freshness code printed on the carton. This code consists of a three-digit Julian date, which indicates the day of the year the eggs were packed. For example, a Julian date of 123 would mean that the eggs were packed on the 123rd day of the year, which is May 5th. Fresh eggs will have a Julian date that is within 45 days of the current date.
- Check the Sell-By Date
In addition to the Julian date, eggs may also have a sell-by date printed on the carton. This date is not an indication of how long the eggs are safe to eat, but rather how long they are expected to maintain their peak quality. Eggs can still be eaten safely after the sell-by date has passed, as long as they are properly stored and have not spoiled.
- Trust Your Senses
Even if an egg has not reached its expiration date, it is still possible for it to be bad. If you notice any unusual odors, flavors, or textures, it is best to err on the side of caution and throw the egg out.
- When in Doubt, Throw It Out
If you are unsure whether or not an egg is bad, it is always best to throw it out. Eating a bad egg can lead to food poisoning, which can cause unpleasant symptoms such as nausea, vomiting, and diarrhea.
By following these tips, you can help ensure that you are only consuming fresh and safe eggs.
Inspect Shell for Cracks
Another way to tell if an egg is bad is to inspect the shell for cracks or leaks. Cracks or leaks in the shell can allow bacteria to enter the egg, which can cause it to spoil. To inspect the shell, hold the egg up to a light and look for any visible cracks or holes. You can also gently shake the egg. If you hear a sloshing sound, it is likely that the egg is cracked and should be discarded.
In addition to cracks, you should also look for any signs of leakage. If you see any dried egg white or yolk on the outside of the shell, it is a sign that the egg has leaked and should be discarded. Leaky eggs can also be contaminated with bacteria.
If you are unsure whether or not an egg is cracked, you can place it in a bowl of water. If the egg sinks to the bottom and lays flat on its side, it is good. If the egg floats or stands upright, it is likely that the egg is cracked and should be discarded.
It is important to inspect the eggs for cracks before you use them, as even a small crack can allow bacteria to enter the egg. Once an egg is cracked, it should be used immediately or discarded.
By following these tips, you can help ensure that you are only consuming fresh and safe eggs.
Float Egg in Water
Another simple way to tell if an egg is bad is to float it in water. This method is based on the fact that fresh eggs are denser than water, while bad eggs are less dense. To float an egg, gently place it in a bowl or glass of cold water.
- Fresh Egg
A fresh egg will sink to the bottom of the bowl and lay flat on its side. This is because the air cell inside the egg is small and the egg is still dense.
- Slightly Older Egg
An egg that is a few weeks old may still be good to eat, but it may not be as fresh as a newer egg. A slightly older egg will sink to the bottom of the bowl, but it may stand upright or bobble slightly. This is because the air cell inside the egg has started to grow slightly larger.
- Bad Egg
A bad egg will float to the top of the bowl. This is because the air cell inside the egg has become too large and the egg is no longer dense enough to sink. Bad eggs should be discarded immediately.
- Cracked Egg
If an egg has a crack in the shell, it will likely float to the top of the bowl. This is because the air has entered the egg and caused it to become less dense.
By following these tips, you can help ensure that you are only consuming fresh and safe eggs.
Smell the Egg
One of the most obvious ways to tell if an egg is bad is to smell it. Fresh eggs should have no odor at all. If you notice any unpleasant odors, such as a sulfurous or rotten smell, the egg is likely bad and should be discarded.
The smell test is especially important for hard-boiled eggs. Hard-boiled eggs can be difficult to inspect visually, as the shell may hide any cracks or discoloration. If you notice any off-smells when you peel a hard-boiled egg, it is best to discard it.
In addition to smelling the egg itself, you can also smell the inside of the eggshell. To do this, crack the egg open and sniff the inside of the shell. If you notice any unpleasant odors, the egg is likely bad and should be discarded.
It is important to trust your sense of smell when it comes to eggs. If an egg smells bad, it is best to err on the side of caution and throw it out.
By following these tips, you can help ensure that you are only consuming fresh and safe eggs.
Look for Discoloration
Another way to tell if an egg is bad is to look for discoloration. Fresh eggs should have yolks that are a deep yellow color and whites that are clear and slightly viscous. Any discoloration in the yolk or white can be a sign that the egg is bad.
- Dark or Greenish Yolk
A dark or greenish yolk is a sign that the egg is old. The yolk of a fresh egg should be a deep yellow color. As an egg ages, the yolk can start to turn a darker color or even develop a greenish tinge.
- Pink or Reddish White
A pink or reddish white is a sign that the egg has been contaminated with bacteria. This can happen if the egg has been cracked or if it has been stored at an improper temperature.
- Black or Blue Spots
Black or blue spots on the yolk or white are a sign that the egg is rotten. These spots are caused by the growth of mold or bacteria.
- Brown or Yellowish White
A brown or yellowish white can be a sign that the egg has been exposed to heat. This can happen if the egg has been left out at room temperature for too long or if it has been cooked at too high of a temperature.
If you notice any discoloration in the yolk or white of an egg, it is best to discard it. Discolored eggs are likely to be bad and can cause food poisoning.
Check for Mold or Bacteria
In addition to looking for discoloration, you should also check the egg for any signs of mold or bacteria. Mold can appear as fuzzy or slimy growth on the shell or inside the egg. Bacteria can be difficult to see, but they can cause the egg to have an off smell or taste.
Here are some specific things to look for:
- Fuzzy or Slimy Growth
If you see any fuzzy or slimy growth on the shell or inside the egg, it is a sign that the egg is contaminated with mold. Mold can cause food poisoning, so it is important to discard any eggs that show signs of mold.
- Off Smell or Taste
If an egg has an off smell or taste, it is likely that the egg is contaminated with bacteria. Bacteria can cause food poisoning, so it is important to discard any eggs that have an off smell or taste.
- Blood Spots
Blood spots are a common occurrence in eggs. They are usually caused by a ruptured blood vessel in the hen's ovary. Blood spots are not harmful to eat, but they can be off-putting to some people.
- Meat Spots
Meat spots are small, reddish-brown spots that can sometimes be found on the yolk of an egg. Meat spots are caused by bits of tissue from the hen's reproductive tract. Meat spots are not harmful to eat, but they can be off-putting to some people.
If you are unsure whether or not an egg is contaminated with mold or bacteria, it is best to err on the side of caution and discard it.
Trust Your Instincts
Sometimes, you can just tell that an egg is bad. Maybe it has an off smell or appearance, or maybe it just feels weird in your hand. If you have a gut feeling that an egg is bad, it's best to err on the side of caution and throw it out.
- Rely on Your Senses
Your senses are powerful tools that can help you determine if an egg is bad. If an egg looks, smells, or tastes off, it's likely best to discard it.
- Be Mindful of Texture
Pay attention to the texture of the egg. A fresh egg should have a firm, slightly sticky yolk and a thick, slightly runny white. If the yolk or white is watery or has an unusual texture, it's best to discard the egg.
- Consider the Egg's History
Think about how the egg has been handled and stored. If an egg has been left out at room temperature for an extended period of time, or if it has been cracked or damaged, it's best to discard it.
- When in Doubt, Throw It Out
If you're unsure whether or not an egg is bad, it's always best to err on the side of caution and discard it. Eating a bad egg can lead to food poisoning, which can cause unpleasant symptoms such as nausea, vomiting, and diarrhea.
By following these tips, you can help ensure that you are only consuming fresh and safe eggs.
When in Doubt, Throw It Out
If you are ever in doubt about whether or not an egg is bad, it is always best to err on the side of caution and throw it out. Eating a bad egg can lead to food poisoning, which can cause unpleasant symptoms such as nausea, vomiting, and diarrhea.
Here are a few reasons why it is better to be safe than sorry when it comes to eggs:
- Eggs can be contaminated with bacteria.
Bacteria can enter an egg through cracks in the shell or through the pores in the shell. Some of these bacteria, such as Salmonella, can cause food poisoning.
- Eggs can go bad quickly.
Eggs are perishable food, which means that they can spoil quickly. The shelf life of an egg depends on how it is stored. Eggs that are stored in the refrigerator can last for up to 45 days, while eggs that are stored at room temperature will only last for a few days.
- It is difficult to tell if an egg is bad just by looking at it.
Some bad eggs may not have any visible signs of spoilage. This is why it is important to use your senses to inspect eggs before you eat them.
If you are ever in doubt about whether or not an egg is bad, it is best to throw it out. It is not worth the risk of getting food poisoning.
By following these tips, you can help ensure that you are only consuming fresh and safe eggs.
