How does FSIS become aware of
clusters (potential outbreaks)?
• Reports from local, state, territorial p
p public
health partners
• CDC and PulseNet
• Consumer Complaint Monitoring System
• Oth f d l agencies (
Other federal i (e.g. FDA military,
FDA, ilit
National Park Service)
• News reports, listservs, etc.

How is product tracing used by FSIS
when investigating outbreaks?
• Determine the source of product causing
p g
illness (as far back as records allow)
• Identify distribution of potentially
adulterated product (trace forward)
• During hypothesis generation help rule in
generation,
or out certain vehicles based on
distribution patterns supplier commonality
patterns,

“As far back as records allow”
• If records do not exist or are of very p
y poor
quality, determining which product to recall
p
is often impossible
• Poor quality records often slow traceback
and, therefore, delay regulatory action

Fiscal Years 2007-2009

Epidemiology & Traceback
• 2008 Salmonella Typhimurium
– FSIS carried out traceback when poultry
initially suspected, results assisted hypothesis-
generation
– Outbreak ultimately linked to contaminated
peanut butter

Epidemiology & Traceback
• 2009 E. coli O157:H7
– Two outbreaks linked to ground beef in the
Northeast
–TTraceback carried out i t d
b k i d t in tandem with
ith
epidemiologic investigation led to more timely
in-plant
in plant action by FSIS

Some real traceback scenarios
• Trace to retail level: no grinding logs
• Trace to retail level: multiple suppliers
• Trace to processor: multiple suppliers or
can’t determine specific dates of
production
• Trace to slaughter plant, can’t determine
specific dates of production
• Trace to farm?

Reasons for unsuccessful
investigations
investigations*
• 4 - Insufficient Product Information
Provided by Public Health Partner
P id d b P bli H lth P t
• 12 - Insufficient Product Information
Provided by Retail or Distributor
• 4 - Lack of Epidemiologic Information
• 2 - Unable to Locate Product for Testing
*Not included: investigations hampered by p
g p y poor information,
,
but not completely unsuccessful. Most investigations
suffer at least partially from poor product information.
