National Enteric Surveillance Program (NESP)

The national incidence of foodborne pathogens is actively collected and reported by the National Enteric Surveillance Program (NESP). The NESP has been in operation since April 1997 and is designed to provide timely analysis and reporting of laboratory confirmed enteric disease cases in Canada. This includes major enteric bacterial pathogens such as:

  • Salmonella
  • Campylobacter
  • Shigella
  • Vibrio
  • Verotoxigenic E. coli, and
  • Yersinia

This also includes intestinal parasitic organisms such as:

  • Giardia
  • Cryptosporidium
  • Entamoeba, and
  • Cyclospora

and enteric viruses such as:

  • Norovirus, and
  • Rotavirus

Our Partners

The program is jointly administered by the Enteric Diseases Program at the National Microbiology Laboratory (NML) and the Centre for Food-borne, Environmental and Zoonotic Infectious Diseases (CFEZID).

Each provincial public health laboratory (as represented by the Canadian Public Health Laboratory Network) provides the NML with weekly aggregate totals of new laboratory confirmed enteric diseases for centralized analysis for detection of emerging and priority disease trends. These analyses are returned in a weekly report to submitting laboratories and other stakeholders such as federal and provincial epidemiologists, researchers and public health professionals. The program also integrates data and information with national (i.e. PulseNet Canada) and international efforts to identify and respond to clusters of foodborne disease.
