The question that raises is whether these eggs are safe to eat, and according to many, they are.
Of course, they need to be properly cooked.
The blood spots are totally harmless, but if you still have doubts about using them in your cooking, you can simply use a knife or another object to remove the spots before using the egg.
The egg whites can also sometimes come with small brown meat spots that are in fact tiny tissue fragments picked up as the egg moves through the oviduct.
These spots, just like the blood spots, pose no danger.
However, if an egg appears to be pinkish or greenish in color, it may indicate the presence of harmful bacteria. These eggs should not be consumed.
