​The detection of a WGS-defined cluster of 17 cases of S. Enteritidis in the United Kingdom in the autumn of 2016 highlights the re-emergence of a strain that was first identified in 2014 and caused an outbreak that was investigated from May to October 2015 in Spain and the UK.
This cluster is part of a multi-country outbreak involving at least four EU/EEA Member States, with 329 confirmed cases that has been ongoing since 2014 and it is being suggested that there might be a common source.
This rapid risk assessment contains an erratum dated 17 February 2017
