Rapid risk assessment update: Outbreak of Shiga toxin-producing E. coli (STEC) O104:H4 2011 in the EU, 8 July 2011

Risk assessment

This document is an update of the EFSA/ECDC joint rapid risk assessment of 29 June and aims to add new information to this and earlier initial rapid risk assessments (27 May and 14 June 2011).
The epidemiological picture of the STEC O104:H4 incidence in Europe suggests a transition phase, from the main outbreak events in Germany and France related to the infected seeds used for sprouting, towards a future risk for new clusters or a continued incidence of sporadic cases. With this objective in mind, specific reporting of new cases occurring at the EU level has been implemented as of 5 July 2011.

ECDC is continuously monitoring the Shiga toxin-producing E. coli (STEC) outbreak and publishes a daily epidemiological update which includes the most recent numbers of haemolytic uremic syndrome (HUS) and non-HUS cases reported by EU Member States.
