According to recently repeated warnings from the Centres for Disease Control, the Department of Agriculture and even the egg industry itself in US, eating eggs in less than hard boiled state may make you ill or even kill you. A particular serotype of Salmonella enteritidis has managed to infect the ovaries of some hens, and so their eggs. Cooking kills the bug, but recipes that use raw or lightly cooked eggs can cause a diarrhoeal disease which, in serious cases can leave victims with arthritis, colon perforations or other complications.
