NTF Annual ConferenceFebruary 16, 2012 Dr. Regina Tan Director, Applied Epidemiology Division Office of Public Health Science Food Safety and Inspection Service Regina.Tan@fsis.usda.gov
Potential Changes in Information Sharing • Special-emphasis Salmonella • As you can imagine, our members will also be especially interested in Salmonella, but you wouldn’t have to talk policy – Dan E. is speaking the next day so I can make sure those type of questions are directed towards him. • If you are available, I’m happy to send over a formal invite. The meeting runs from 1-5pm and we can work around your schedule as to which specific time would be best. This slide contains quotes from the original presentation request. It’s purpose is only to ensure the presentation is written to meet the needs of the audience. The slidewill be deleted prior to presentation delivery.
Proposed Agenda • Bottom Line Up Front • Foodborne Illness Investigations • Directive 8080.3 • Anatomy of an investigation • Information-sharing opportunities • Example traceback • Consumer Complaints • Directive 5610.1 • Anatomy of a complaint investigation • Information-sharing opportunities
Bottom Line Up Front • Partners in prevention • Shared importance in safety of food • Shared importance in consumer trust • Always opportunities to improve • Welcome conversations to do so
Directive 8080.3 • Key Points : • Factors determining whether to submit a product sample • Collecting, preparing, and shipping product samples • Field activities during a foodborne illness investigation (Environmental assessment) • Procedures for analyzing data • Agency responses to the findings of a foodborne illness investigation FSIS Homepage search “8080.3”
Anatomy of an Investigation Was the sample intact? Did it suffer temperature abuse? Was it properly stored to avoid cross-contamination? Are the product labels available for product identification? *Initiate Investigation
Anatomy of an Investigation Did exposure precede illness? Was illness consistent with known clinical characteristics? Do Traceback/Forward suggest common source? Are findings consistent with Agency experience? Was disease confirmed by laboratory analysis? Concurrent activities require constant communication
Points of Communication • Directive 8080.3 • CDC leads public health coordination • OPHS AED leads internal FSIS coordination • OFO leads coordination with establishment • Discussion: Potential opportunities for communication
Directive 5610.1: Origins • March 2001 OIG Investigation Report • CCMS established in November 2001 • Provide centralized mean of managing consumer complaints.
Directive 5610.1 • FSIS Directive 5610.1 – Procedures to Implement the Consumer Complaint Monitoring System
CCMS The System • Purpose: Facilitate detection of potential public health threats in the nation’s food supply and enable rapid response to mitigate such threats. • The CCMS System: Electronic database • Records Consumer Complaints for documentation • Triages Complaints for evaluation • Tracks and coordinates investigation
Anatomy of a Complaint Investigation CCMS System FNS, ODIFP, OPPD and other USDA Program Areas CCMS Team FSIS OPHS AED
Investigation Information • Consumer Contact Information • Complaint • Type: Foreign object, Allergy, Illness, Other • Description (symptoms, symptom onset time, known allergies, etc) • Food history, medical history, etc. • Product Information • Brand • Establishment number • Lot codes/sell by dates, package size and type • Point of Purchase Information • Name & location • Purchase date
Issues Not Entered in CCMS • Whistle-blower • Industry complaints initiated by a competitor • Retail-prepared product • Product tampering • Criminal violations of the FMIA, PPIA or EPIA • National School Lunch Program complaints NOT involving an FSIS product • Quality issues involving meat cuts and grades • General concerns or comments
CCMS Issues • Initiated by a consumer or on the consumer’s behalf • Directly related to an FSIS-inspected product • Imported products re-inspected by FSIS at the port of entry • Complaint types: • Illness • Foreign Object • Injury • Allergic Reaction • Improper Labeling • Poor Quality • Economic Adulteration Pictures from the USDA Kitchen Companion
Multiple Locus VNTR Analysis Protocol http://www.pulsenetinternational.org/SiteCollectionDocuments/mlva/MLVA_overview.pdf
Current State of MLVA http://www.aphl.org/conferences/proceedings/Documents/2007_11th_Annual_PulseNet_Update_Meeting/MLVA_Protocol%20Update.pdf
Limitations of MLVA Use • To date, several schemes for MLVA subtyping of S. enteritidis have been published. • However, the use of: • Different loci in each protocol (or different promers for the same loci) • Different sequencer platforms • Dye chemistries and size standards used for fragment analysis • Differences in interpretation of loci where incomplete TRs or TRs of heterogeneous sequence occur, and • Different ways of assigning allele numbers • means comparison of data between laboratories can be problematic.
