28 July, 2006

Twenty-one cases of Salmonella Enteritidis phage type 13a have been identified among attendees of an outdoor charity event which was held in Hertsmere, Hertfordshire, on 18 June 2006.
After reports of illness among attendees were received, an investigation led by Hertsmere Borough Council, the London borough of Barnet, Bedfordshire and Hertfordshire Health Protection Unit, and the East of England Regional Epidemiology Office of the Health Protection Agency was started.
About 600 people (mostly children) attended this outdoor charity event which took place during 18 June 2006. The event consisted of two sessions of team games played by children. Those who attended lived in Hertfordshire or north London.
Food was served at the event. This included bread rolls with various fillings including egg, prepared by a caterer. At least 65 attendees are known to have developed illness after the event.
Twenty-seven cases of salmonella have been identified among the attendees and 21 of these cases have Salmonella Enteritidis phage type 13a. Inspections have been made by Environmental Health Officers to the site of the venue and to the premises of the supplier of the filled bread rolls. Investigations are continuing and a case-control study is being conducted (HPA).
