Rapid Risk Assessment: Cluster of new Salmonella serotype cases in four EU Member States, 20 March 2017

​Since March 2016, four EU Member States have reported a total of 40 cases of a new Salmonella serotype with an antigenic formula which has never been described before.  Pulsed-Field Gel Electrophoresis (PFGE) and Whole Genome Sequencing (WGS) have confirmed the genetic closeness of the Salmonella isolates, suggesting a common source of infection. This risk assessment discusses the suspected vehicle of infection and assesses the threat to public health in the European Union/European Economic Area.
