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
Recall – Stop Ongoing Exposure
Common Farm for Seed Source
Epidemiology

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
