Is Blood in an Egg Bad?

Did you just crack an egg and find blood? Then this post is for you.

As a big consumer of farm fresh eggs, I’ve found blood spots many times. Sometimes, there might be multiple blood spots, or the egg white can be tinged with blood as well.

So why does this happen and can you still eat the egg? And if you actually own the hen that laid the egg, is her health still o.k.?

In this post, I briefly answer these questions and more.

Can I Eat Eggs With Blood Spots?

Yes, you can definitely eat an egg if you find a blood spot in it. The egg is perfectly safe to eat whether or not to remove the blood.

If you do choose to remove the blood spot, just take the tip of a knife and take the spot out. You can then safely cook the egg like a regular egg.

If the entire white of an egg is pink or red, it’s best to throw it out. This color might mean the egg isn’t safe to eat because of bacteria.

Another type of spot regularly found in egg whites is called a meat spot. These spots appear as brown, red, or white deposits. Eggs with meat spots are also edible.

The Cause of Blood in an Eggs

Usually, blood in chicken eggs is not anything to be worried about. The cause of a blood spot is simply a ruptured blood vessel on the yolk’s surface as the egg is forming inside a hen.

Each egg includes blood vessels which, if fertilized and later incubated, will eventually benefit the growing embryo.

But a blood spot in your egg doesn’t mean that the egg has been fertilized. Even non-fertile eggs have tiny blood vessels that secure the yolk firmly in position within the egg.

In chicken eggs, the actual cause of blood spots may vary. Here are a few common reasons:

  • Stress: The hen might have been startled while she’s forming the egg.
  • Handling: The hen might have been handled roughly while the egg is being formed.
  • Genetics: Blood in chicken eggs can be genetic and there’s little you can do about it.
  • Lighting: Lighting the coop through the winter or exposing the hens to excess light could also cause blood spots.
  • Nutrition: Blood spots could be caused by too much or too little vitamins and minerals in the hens’ diet. Make sure you’re feeding your hens a layer feed high-quality layer feed.
  • Age: Young hens who just started laying eggs, and old hens who are about to retire their egg-laying, tend to lay more eggs with blood spots.

More dangerous, but uncommon, causes of blood spots may include fungus or toxins in the feed or a viral disease (Avian encephalomyelitis).

How to Prevent Blood Spots in Eggs

Blood spots are completely natural and, unfortunately, there is no way to prevent them from happening.

Blood Spots in Store Bought Eggs

You’ve probably never seen blood spots in store-bought eggs. Why is that?

To reduce the risk that eggs with blood spots aren’t sold to customers, commercially sold eggs go through a process called candling. This technique detects flaws within the egg by using a bright light. If flaws are found in the egg, the egg is discarded.

Unfortunately, some eggs with blood and meat spots aren’t caught by the candling process. For example, blood spots in brown eggs are more difficult to detect than white eggs because of its darker colored shell.

How to Candle Eggs

People who eat farm-fresh eggs are more likely to find blood spots than people who eat eggs produced commercially. This is because local farms or backyard chicken keepers usually don’t candle the eggs.

But if you’re interested in candling eggs, check out my favorite candler from Amazon. It’s really cool and easy to use.


That’s it! I hope this post about finding blood in an egg helped you out!
