Public Health Investigation of Salmonella Enteritidis in raw shell eggs in England and Wales

In response to a dramatic change in the epidemiology of Salmonella enterica serotype Enteritidis in England and Wales, thought to be associated with raw shell eggs (1), the Public Health Laboratory Service (PHLS) has initiated an outbreak-related Public Health Investigation (PHI) (2). Raw shell eggs from premises linked to outbreaks of S. Enteritidis, or their sources of supply are examined for Salmonella spp. and isolates are sent to the Laboratory of Enteric Pathogens (LEP) for confirmation and typing. The results to date are shown in the table below.
