The enemy within us: lessons from the 2011 European Escherichia coli O104:H4 outbreak

In response to the 2011 European health alert caused by a pathogenic Escherichia coli O104:H4 outbreak, the European Academy of Microbiology (EAM), established by the Federation of European Microbiological Societies (FEMS), convened a meeting in Paris on November 30th, 2011 on 'EHEC infection and control' attended by world renowned experts in pathogenic E. coli. The major aims of this group were to review the scientific issues raised by the outbreak, to assess the handling of the crisis at the scientific and political levels, and to propose future actions. Several conclusions, which will have impact on future potential E. coli outbreaks, are outlined here.
