The burden of foodborne disease is not well defined in many countries or regions or on a global level. The World Health Organization (WHO), in conjunction with other national public health agencies, is coordinating a number of international activities designed to assist countries in the strengthening of disease surveillance and to determine the burden of acute gastroenteritis. These data can then be used to estimate the following situations: (1) the burden associated with acute gastroenteritis of foodborne origin, (2) the burden caused by specific pathogens commonly transmitted by food, and (3) the burden caused by specific foods or food groups. Many of the scientists collaborating with the WHO on these activities have been involved in quantifying the burden of acute gastroenteritis on a national basis. This article reviews these key national studies and the international efforts that are providing the necessary information and technical resources to derive national, regional, and global burden of disease estimates.

WHO Global Salm-Surv. Launched in January 2000, the WHO Global Salm-Surv is an international capacity-building program that strengthens national laboratory-based surveillance and outbreak detection of and response to diseases commonly transmitted by food. It is coordinated by the WHO, the Danish Institute for Food and Veterinary Research, the Centers for Disease Control and Prevention (CDC), Reseau International des Instituts Pasteur, the Public Health Agency of Canada, Animal Sciences Group (The Netherlands), US Food and Drug Administration, Enter-net, and OzFoodNet (Australia) . The core elements include international training courses, an electronic discussion group, a Web site , an external quality-assurance system, a country databank of the top 15 annual Salmonella serotypes, focused regional and national projects, and reference-testing services. Through 2004, 26 training courses for microbiologists, epidemiologists, and managers have involved ∼350 participants from 190 countries. By enhancing laboratory-based surveillance, WHO Global Salm-Surv is helping countries establish a foundation on which to estimate the burden of foodborne disease.
