Blood in Egg

Blood spots occur in up to 6% of brown eggs. Some of those spots disappear over time and the rest are removed during the processing stage. The small number that reach the store shelf are a little bit icky to some, but entirely safe and natural.

Yep...not the most appetizing sight when you're making breakfast. Nobody likes cracking an egg and seeing anything other than a beautiful, richly colored yolk nestled in a clear egg white. But once you learn a little more about blood spots (and all the other fascinating ins and outs of eggs), you might be a little less grossed out by these rare instances.

What are blood spots in eggs?

Contrary to popular belief, blood spots are not the beginnings of a chick embryo. They're simply the remnants of a ruptured blood vessel that occured during the egg's formation. Most often, the ruptured vessel forms a tiny speck or dot of blood with a dark red, brown, or even black hue. Sometimes, larger vessels burst, and this allows blood to pool throughout the entire egg. In these cases, the egg white may have a pink or red tinge. In either case, these blood spots are a natural part of egg laying. In fact, blood spots indicate a particularly fresh egg because as they age, the spot diffuses into the white and becomes undetectable.

What causes blood spots in eggs?

The cause of a blood spot is simply a ruptured blood vessel on the yolk's surface as the egg is forming. This is a natural, benign process for both hen and egg. Instances of blood spots can increase when hens in a flock get excited by changes in lighting, changes in temperature, or simply shifting seasons. So it's okay if it feels a little bit yucky, but know that all is well.

Can I eat an egg with blood in it?

Absolutely – eating an egg that has a blood spot won't hurt you. While you may wish to remove the spot with the tip of a knife and dispose of it, there is nothing in it that's harmful for human consumption.

How can you prevent blood spots in eggs?

Since blood spots are a perfectly natural part of the egg laying process, there is no way to prevent this from happening. However, we do have state-of-the-art processing equipment that helps us detect eggs with imperfections and filter them out before they ever make their way into our packaging—be they slightly cracked, misshapen, or containing other slight imperfections.

In fact, 99% of Nellie's Free Range Eggs reach the store in perfect condition. We find almost everything. But no process is perfect, and there will always be the very occasional feather on an egg, hairline crack, or blood spot that makes its way past the machines' and our keen eyes.

Are blood spots kosher?

Our eggs are certified kosher by the OU, but things get a little tricky on the rare occasion of blood or a blood spot making it into a carton. According to the OU, eggs with blood or blood spots in them are not considered kosher.

I did not have "blood spots" in your eggs; I had LOTS OF BLOOD, as in completely red egg whites.


We're so sorry to hear you experienced this Nancie. It sounds like you had some bloody eggs which are no doubt unappetizing. We'd love to look into this issue a bit further if you wouldn't mind sending us an email to: [email protected] Thank you!

All but one egg in my carton had blood spots in them. I have my own chickens, never have I had blood spots. I won’t be purchasing again. Too expensive to crack an egg and see blood.


Hello Heather. We're very sorry to hear that you experienced so many blood spots in one batch. We'd be glad to look into the issue if you wouldn't mind sending us an email to: [email protected] Thank you!

I have found with brown eggs in general there is frequently a blood spot. I buy your eggs regularly and find spots pretty frequently. I'm glad to know that it is harmless and not a fertilized egg. Logic told me it likely didn't mean the egg was fertilized but thank you for the reassurance.


We are so glad our article could help eggucate you on your everyday kitchen findings!

I cracked an egg today and blood ran out of the egg and then I realized it was dark brown inside and attached to the wall of the shell. Absolutely horrifying. I don’t mind the little red spots but this was full on blood and pretty sure it had been fertilized.


Oh no! We're so sorry to hear this Katherine. While we don't have any roosters with our hens and we don't offer fertilized eggs, we'd love to look into this right away. Could you send us an email with the carton information? Our email is: [email protected] Thanks!

I was very confused and disappointed due to that eggs with blood spots. I always destroy all eggs when i found blood spots. Know i am satisfied to know about these spots that are normal.


Hi Jiya, we're happy we could help!

I broke and disposed of 6 out of 18 Nellie's eggs due to blood spots. They are very expensive, so I probably won't be purchasing them anymore. Even if they are ok to eat, I just can't.


We're so sorry to hear about this, Carol. If you don't mind sending us an email at [email protected], we'd love to replace this carton for you and collect some information for our quality team.

I will be buying cage free eggs from now on. Rarely do I find a blood spot in them. Perhaps that is due to the candling process. I would prefer free range, however, I find blood spots unappetizing.


We're so sorry to hear that, Mary. If there's anything we can do to convince you to give our eggs another chance, please don't hesitate to send us an email at [email protected]

Gloria DiGrandiApril 15, 2019

Ok so far I've thrown away 3 "spotted" eggs...ugh I can't eat them. It's hurts that they are expensive eggs. Thanks for the info.just letting you know about this. They are my favorite brand, though.

We appreciate you taking the time to read about the cause of blood in eggs and would love to send you some coupons to use toward your next carton. If this is of interest, please send us an email at [email protected] We appreciate your support!

Thank you for the information, I always thought it was bad and disposed of one of your eggs. Now I know, I feel secure with your eggs.


You're very welcome, Craig. We're so glad that this information helped put your mind at ease. If you ever have questions or concerns about a particular egg or carton, please don't hesitate to reach out!

Thank you. I often wondered about the blood spots and my Swedish nana always told me it was nothing to worry about.


You're very welcome, Janet! Nana usually knows what's best and this case was no exception!
