Human disease surveillance
• Pathogen-specific human disease surveillance
• Illness notification / complaint systems
• Syndromic surveillance

Product Tracing
• Key Concepts– Trace-back is only as good as the
epidemiology– The more specific, the better the results– Oftentimes, solving an outbreak
requires good evidence from both the epi and the trace-back
Epidemiology meets Trace-back
Cluster of Cases that match by PFGE subtype
Common Exposure – Same Restaurant Chain – Varying locations
All Cases Consumed Sprout Containing Sandwiches
Different Suppliers for each Restaurant
Different Growers for each Supplier
Common Seed Source for each Grower
Common Farm for Seed Source
Epidemiology
“Epi” Trace-back

Initial case-control study/traceback results to CDC
Salmonella Saintpaul Investigation
• Illustrates:– Combination of rapid epidemiological
and traceback investigation– Identify source as jalapeño peppers– Trace peppers back to Texas– Joint communications with FDA and
CDC
Salmonella Typhimurium Investigation
• Illustrates:– Combination of rapid epidemiological,
traceback and laboratory identification– Identify source as peanut butter– MDA Lab finds Salmonella in King Nut– Joint communications with FDA and
CDC
