  9. 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

  10. 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 On-going Exposure Common Farm for Seed Source Epidemiology meets Trace-back Epidemiology “Epi” Trace-back
