                                                     The mission of the WHO Department of Food Safety and Zoonoses is to lower the burden of disease from food and
                                                     animals, focusing on industrialized and traditional production systems, and integrating prevention from farm to table.
                                                     This work includes the provision of scientific advice, efficient standard setting, and clear communication in support of
                                                     foodborne and zoonotic disease prevention and international efforts to food-related outbreak detection and response.
              conduct epidemiological reviews for mortality,
              morbidity and disability in each of the major foodborne
              diseases;
              assemble, appraise and report on existing burden of
              foodborne disease estimates, where data is lacking;
              provide models for the estimation of foodborne disease
              burden;
              develop source attribution models to estimate the
              proportion of disease that is foodborne;
              develop user-friendly tools for burden of foodborne
              disease studies and policy situation analyses at
              country level.
              Track 2) Implemented during 2009, the second track of
              the Initiative focuses on burden of foodborne disease
              studies at country level. These studies provide first hand
              burden estimates and supplement FERG's epidemiologi-
              cal reviews.
     This Initiative responds to a call from international partners for WHO to coordinate and lead the burden assess-
     ment, and reflects WHO's implementation of the WHO Global Strategy for Food Safety, as endorsed by the
     Executive Board in January 2002. It incorporates all principles and goals of the WHO Strategy on Research for
     Health, presented to the Bamako ministerial forum in November 2008.


       Expected results
 •     Global report and global atlas of the burden of all relevant enteric, parasitic and chemically caused
       foodborne diseases by 2013.
 •     A peer-reviewed paper series in a high-impact journal with at least 50% of contributing authors from
       developing countries.
 •     Foodborne disease burden and policy situation analyses country studies (in each of the six WHO
       regions).
       Achievements to date
 •     Development of the Global Strategy to Estimate the Global Burden of Foodborne Diseases,
       including a communications strategy and a monitoring and evaluation framework.
 •     Appointment of a multi-disciplinary Foodborne Disease Burden Epidemiology Reference Group
       (FERG), which serves as an external, technical advisory body to the Initiative.
 •     Preliminary burden of disease results published in October 2009 on diarrhoeal diseases in persons
       older than 5 years of age, and selected parasitic diseases and peanut allergies.
 •     Institutionalization of interactions and exchanges with the stakeholder community (governments,
       industry, donors, consumers, media) to ensure that the Initiative's results are meaningful and of
       practical use to all food safety constituencies.

        Planned activities for 2010-2011:
– Technical meetings of the FERG Task Forces to advance the burden work in the following areas: parasitic
  and enteric diseases, chemicals and natural toxins, source attribution, and country burden assessment
     • Annual Foodborne Diseases Stakeholder Meeting
     • Pilot country burden of foodborne disease studies
     • Pilot policy situation analyses
     • Commissioning of systematic reviews and major research studies
