Safety of blood spots in egg yolks

Overview

Information regarding red or brown spots in egg yolks indicates that these inclusions are harmless blood or tissue traces from the hen that enter the yolk during the natural egg-forming process. These spots do not signify embryo development or issues with food safety, nutritional value, or animal health.

In Sweden, it is noted that such spots occur when a tiny blood vessel in the hen’s ovary or oviduct ruptures. These are more common in fresh, farm-produced eggs, as industrial sorting equipment typically removes them before packaging.

In Germany, these inclusions, sometimes referred to as ‘Hahnentritt’, are particularly common in older laying hens. Data from 2025 shows that German companies produced over 13.7 billion eggs, with approximately 15 percent of total production containing such small inclusions. Consumers can safely consume these eggs by removing the discoloration with a spoon or knife before preparation.
