Cracking an egg is usually one of the simplest parts of preparing a meal. But every so often, you may notice a tiny red, pinkish, or brown mark near the yolk. For many people, that unexpected spot immediately raises concerns about whether the egg is fresh or safe to eat.
The good news is that a small red spot inside an egg is usually a natural occurrence. These marks are commonly called blood spots, and their presence alone does not mean the egg has spoiled.
Still, it is useful to understand why they appear and what other changes could indicate that an egg should be discarded.
Why Do Red Spots Appear?
Blood spots can develop when a very small blood vessel breaks while an egg is forming inside the hen. A tiny amount of blood can then become incorporated into the egg and remain attached to the yolk or appear in the surrounding white.
The spot may look bright red when the egg is fresh, while older spots can appear darker, brownish, or rust-colored.
Importantly, finding one does not mean the egg contains a developing chick. Eggs sold commercially are generally unfertilized, and blood spots are simply a natural result of the egg-forming process.
Why Are They Not Common?
Most supermarket eggs go through quality-control procedures before reaching consumers. One traditional inspection method is called candling, in which eggs are examined using light to identify cracks and certain internal imperfections.
Very small spots can sometimes escape detection, however. This is particularly understandable when the mark is tiny or difficult to see through the shell.
That is why occasionally finding a blood spot in an otherwise normal carton does not necessarily indicate a problem with the eggs or the inspection process.
What About Brown Eggs?
There is a common belief that brown eggs are more likely to contain blood spots. The situation is more complicated.
Darker shells can make it more difficult to see very small internal details during inspection because less light passes through the shell. Consequently, some minor spots may be harder to identify.
The color of an eggshell itself does not mean that an egg is healthier, fresher, or safer. Shell color is primarily determined by the breed of the hen.
What Is a Meat Spot?
You may occasionally find a small brown or grayish particle inside an egg that is not actually a blood spot.
These are sometimes called meat spots. Despite the name, the term does not mean that you have found a piece of meat in the egg. Such marks can consist of tiny pieces of tissue or material associated with the egg-forming process.
A small spot of this type is generally considered a quality issue rather than automatic evidence of spoilage. If you prefer not to include it in your meal, you can simply remove it before cooking.
When Should an Egg Be Thrown Away?
A tiny red spot is generally not the main thing to worry about. Instead, pay attention to the egg’s overall condition.
An egg should be discarded if it has obvious signs of spoilage or contamination, such as:
- A strong or unpleasant odor
- Mold
- Unusual widespread discoloration
- A badly cracked or leaking shell
- Strange material on the shell
- Evidence that it was stored improperly for an extended period
If an egg smells distinctly rotten after being cracked, do not taste it to determine whether it is safe. Dispose of it instead.
It is also a good idea to inspect questionable eggs individually rather than automatically assuming that an entire carton is unusable.
A Simple Kitchen Habit Can Help
One easy practice is to crack eggs into a separate, clean bowl before adding them to a larger recipe.
This gives you an opportunity to check the egg’s appearance and smell. If one turns out to be questionable, you can discard it without contaminating an entire mixture.
It also makes it easy to spot and remove a small blood or meat spot if you would rather not cook with it.
Does the Floating-Egg Test Prove Anything?
Many people have heard that putting an egg into a glass of water can reveal whether it is fresh.
As eggs age, air gradually enters through the shell and the internal air pocket becomes larger. Older eggs may therefore stand upright or float, while fresher eggs tend to remain lower in the water.
However, the water test is not a reliable food-safety test. A floating egg is not automatically spoiled, and a sinking egg is not guaranteed to be free from harmful bacteria.
Instead, consider the egg’s storage history, shell condition, appearance, and smell, and follow proper cooking practices.
Store Eggs Correctly
Proper storage is far more important to egg safety than a tiny red spot.
When shopping, choose eggs from a properly refrigerated display and avoid cartons containing cracked or leaking eggs.
Once you get home, refrigerate the eggs promptly. Keeping them in their original carton can help protect them from odors and moisture loss while also keeping useful date information available.
For more consistent temperatures, store eggs on an interior refrigerator shelf rather than in the door.
If you are buying commercially packaged eggs in the United States, there is generally no need to wash them again at home. Additional washing can potentially spread contamination around the kitchen.
As with other raw foods, wash your hands, utensils, and preparation surfaces after handling raw eggs.
Cook Eggs Properly
Thorough cooking is another important part of reducing food-safety risks associated with eggs.
For everyday meals, cook eggs until the whites and yolks are firm. Egg dishes such as casseroles should also reach a sufficiently hot internal temperature.
If you are preparing foods that contain raw or lightly cooked eggs, such as certain homemade sauces or desserts, consider using pasteurized eggs or pasteurized egg products.
Extra precautions are particularly important when preparing food for people who may be more vulnerable to foodborne illness.
The Bottom Line
A tiny red spot inside an egg can certainly look unusual, but in most cases, it is simply a natural blood spot created during the egg’s formation.
If the egg has been properly stored, has no unpleasant odor, has an intact shell, and otherwise looks normal, a small spot alone is generally not a reason to panic. You can remove the spot if you prefer and then cook the egg properly.
However, clear signs of spoilage—such as a foul smell, mold, leakage, or unusual widespread discoloration—are reasons to throw the egg away.
So the next time you crack an egg and discover a tiny red mark, don’t assume the worst. One small spot usually tells you much less about an egg’s safety than its storage, condition, smell, and handling.
