What are the food safety risks?

Cooked egg yolks can be a breeding ground for bacteria such as Salmonella if not stored properly. To reduce the risk of foodborne illness, it is crucial to refrigerate cooked egg yolks promptly and ensure they are heated to a safe internal temperature of 160°F (71°C) when cooking.
