3. Product Tracing Challenges: FDA Perspective
Starting Points
• A traceback investigation starts with the
consumer or the point-of-purchase and traces
the distribution of the product back to the
source/farm. This is the process used in
response to a foodborne illness outbreak.
• A traceforward investigation begins with the
source/farm or manufacturer/distributor and
traces f
t forward t the consumer. This process i
d to th Thi is
used for a product recall and it can also be
useful in outbreak investigations.

• May be conducted to:
1) identify the source and distribution
of implicated f d and remove
f i li d food d
contaminated product from marketplace,
2) di ti
distinguish b t
i h between t
two or more i li t d
implicated

5. Product Tracing Challenges: FDA Perspective
Traceback Challenges
• FDA faced a number of challenges while
conducting traceback investigations of fresh
p
produce including:
g
– an ongoing outbreak
– large numbers of sporadic cases
– poor consumer recollection of consumption history
(e.g. multiple days consumption of same produce)
and lack of specific product information
– multiple product varieties identified
– multiple products w/multiple ingredients identified

6. Product Tracing Challenges: FDA Perspective
Traceback Challenges Specific to Produce
• Consumer level
– Lack of packaging/labels
– Lack of consumers’ ability to distinguish the type of
consumers
produce especially when sliced, chopped or served in
dishes such as salsa and guacamole
• Distribution level
– Lack of consistent product descriptions on records
–CCo-mingling of produce f
i li f d from multiple sources
li l
– Lack of lot numbers, lack of integrity of lot numbers

7. Product Tracing Challenges: FDA Perspective
Traceback Challenges Specific to Produce
• Distribution level (cont’d)
– Co-mingling & loss of source identity
– Co-ops
– Records - Inability to determine specific source,
farm/fields, harvesting information by shipment or
, g y p
production day
– Large numbers of possible sources contributing to
specific “lots”
lots
– Lot number not carried through on subsequent distribution
records
