Four patients with Salmonella enteritidis infection are reported. All were body builders who regularly consumed substantial quantities of raw eggs. They presented with a severe febrile illness and diarrhoea--presumably reflecting a large bacterial inoculum. Advice regarding the potential hazards of raw egg ingestion has been repeatedly issued by the Department of Health--but this report highlights the fact that this practice continues in spite of this. The epidemiology of S. enteritidis infection in relation to raw egg ingestion is discussed.
