Egg yolk spots explained: Safety of red or brown inclusions
Red or brown spots found in egg yolks, often referred to as 'Hahnentritt', are not a cause for concern regarding food safety or embryo development. These spots are actually tiny traces of blood or tissue from the hen that enter the yolk during the natural egg-forming process.
According to the Verbraucherzentrale Bayern, these inclusions are particularly common in older laying hens and do not reflect the health of the animals or the quality of their housing. While the spots can appear in both white and brown eggs, they are more frequently seen in brown eggs in supermarkets due to industrial inspection processes where machines use light to scan eggs.
In 2025, German companies produced more than 13.7 billion eggs, with approximately 15 percent of total production containing such small inclusions. Consumers can safely consume these eggs by simply removing the discoloration before preparation.
