Aims:  In response to a dramatic change in the epidemiology of Salmonella Enteritidis in England and Wales thought to be associated with raw shell eggs, the Health Protection Agency initiated public health investigations to establish the incidence of Salmonella contamination and origin of eggs used by catering premises implicated in outbreaks of Salm. Enteritidis.

A remarkable decline in nontyphoidal salmonellosis in the United Kingdom since the late 1990s coincides closely with the introduction of voluntary vaccination programs in broiler-breeder and laying
Risk assessment of Salmonella from shell eggs

The purpose of this paper is to seek the Committee’s advice on whether the risk to consumers (including vulnerable groups) from consuming lightly cooked or raw shell eggs and their products has
Egg-borne infections of humans with salmonella: not only an S. enteritidis problem
The principal salmonella serovar associated with infections linked to eggs and egg products in the UK, most European countries and North America is Salmonella enteritidis. However, other serovars
Determination of Salmonella in egg shell and egg content in some selected areas of Bangladesh
The study shows that, true prevalence of Salmonella in egg shell and egg contents were 0.093% and 0.068% respectively, and the average frequency of egg shell contamination is positively correlated with re-use of egg tray without disinfection.
Survey of Salmonella contamination of raw shell eggs used in food service premises in the United Kingdom, 2005 through 2006.
The study showed evidence of poor egg storage and handling practices in food service premises, in that 55% did not store eggs under refrigerated conditions; 20.7% of eggs had expired "best before" dates or were in use after 3 weeks of lay, indicating poor stock rotation; and 37.1% pooled eggs not intended for immediate service.
Investigation of the Concurrent Emergence of Salmonella enteritidis in Humans and Poultry in British Columbia, Canada, 2008–2010
A multi‐sectoral collaboration during a 3‐year investigation of Salmonella enteritidis in British Columbia led to data sharing, improved understanding of SE, engagement with the poultry industry and public communication, and the actions taken by public health and animal health professionals.

The study showed that egg pools, feed samples and water samples were negative for Salmonella spp.
Surveillance for foodborne pathogens in humans
This chapter describes some of the surveillance methods that can be used and gives examples of their usage on a national and international basis and summarises the limitations of surveillance activities and some future trends.


Salmonella and raw shell eggs: results of a cross-sectional study of contamination rates and egg safety practices in the United Kingdom catering sector in 2003.
The Salmonella contamination rate of eggs produced in the United Kingdom appears to have decreased significantly since 1995 and 1996, and this trend is reflected in the decrease ofSalmonella Enteritidis and, in particular, Salmonellosis PT4.
Foodborne general outbreaks of Salmonella Enteritidis phage type 4 infection, England and Wales, 1992–2002: where are the risks?
The decline in the S. Enteritidis PT4 epidemic is described, providing evidence that control measures introduced, e.g. improved biosecurity and vaccination, have worked and continued surveillance of human and veterinary salmonellosis is essential to detect future problems.

A phage-typing scheme for Salmonella enteritidis
A phage-typing scheme for S. enteritidis is described and to date differentiates 27 types using 10 typing phages.
Egg age and the growth of Salmonella enteritidis PT4 in egg contents
The growth of Salmonella enteritidis PT4 in albumen around an intact yolk was governed by the age of the egg on inoculation and would appear to be temperature related and took place more rapidly when eggs were stored under conditions where temperatures fluctuated and, on occasions, reached 30° C.
