It is not recommended to feed soft runny yolks to children, as the egg yolk may contain bacteria called Salmonella Enteritidis, which could cause infections in children. Salmonella Enteritidis is destroyed when eggs are completely cooked. Soft runny yolks of soft boiled eggs are not cooked; they are simply warmed, and that is not sufficient to kill the bacteria Salmonella Enteritidis. To check for infections, one must be aware of the symptoms of Salmonella. An infected person will get diarrhoea, fever and abdominal cramps with the symptoms lasting from four to seven days.
