The key issues to be addressed by PEN are: 

1. Methods of detection and molecular characterisation of E. coli O157 and other potentially pathogenic strains and serotypes of E. coli.

2. Epidemiology and transmission of E. coli O157 and other potentially pathogenic strains and serotypes of E. coli

3. Virulence and emerging pathogenic E. coli.

4. Ecology of E. coli O157 and other potentially pathogenic strains and serotypes of E. coli.

5. Control and management of E. coli O157 and other potentially pathogenic strains and serotypes of E. coli.
