Salmonella outbreak in Wrexham declared “closed” after 33 confirmed cases

Public Health Wales have named the ‘exposure site’ of a salmonella outbreak in Wrexham for the first time, and have detailed work that was carried out over the last month in dealing with the issue.

Richard Firth, Consultant in Public Health at Public Health Wales, and Chair of the OCT, said in a statement released this lunchtim: “Following the identification of several cases of Salmonella in Wrexham, on July 31 2023, a multi-agency Outbreak Control Team (OCT) was established including representation from Public Health Wales, Betsi Cadwaladr University Health Board and Wrexham County Borough Council’s Environmental Health Team.

“We can confirm a total of 33 confirmed, genomically identical, cases of salmonella infection and 1 probable case associated with The Nags Head public house on Mount Street, Wrexham, owned by Marston’s PLC.

“On July 31, control measures were put in place, which included a voluntary closure and deep clean of the premises, and testing of all staff. No further cases have been identified since the control measures were put in place.

“Whilst all the evidence indicates the exposure site for the infections being The Nags Head, extensive investigation and testing has not identified the precise source or route of transmission for the infections.

“Public Health Wales would like to extend our sympathies to those affected by this outbreak. We would also like to thank our multi-agency partners as well as the management and staff at both The Nags Head and Marston’s PLC. for their proactive support throughout this investigation.

“Infection with Salmonella can cause watery and sometimes bloody diarrhoea, abdominal pain, headache, nausea, vomiting, and fever. Salmonella is one of a number of organisms that gives rise to illness collectively known as ‘food poisoning’.

“Although it is an unpleasant illness, most people who become ill with Salmonella generally make a full recovery, but serious complications may occur in frail, elderly people, very young children and people with impaired immune systems.

“Anyone who is concerned about their health should contact their GP or call NHS Direct Wales on 111.”
