Document Summary
Why do surveillance of foodborne diseases? identify health status of populations. Find cases, isolates of infectious agents, support recall of implicated food identify and quantify disease trends: detect changes in agents, risk factors, health practices. Attribute illness to specific foods, practices or settings: determine human health burden of disease, prioritize interventions/prevention strategies. Monitor and evaluate their impact: guide public health planning and policies. Under-reporting can be a problem and impact research results. Active surveillance: actively going out and search for cases, often occurs during outbreak situations reminders to data providers costly typically limited to rare diseases, sentinel programs, research studies. Sentinel surveillance relies on a pre-arranged sample of reporting sources who agree to report all the cases. Good for common diseases: detailed information and sampling from sentinel site. Integrated food-chain surveillance: data from humans, animals and food, generate hypotheses about:
