Boosting the ROI of Your PMP: Using Data to Optimize Your Pathogen Environmental Monitoring ProgramTimothy Freier, Ph.D.
PNW Food Safety & Sanitation Workshop
Portland, OR, November 2018
For several decades, mainly a concern for dairy and RTE meat and poultry
New outbreaks and improved public health surveillance (since 2010) Chopped celery Cantaloupes Caramel apples Ice cream Packaged leafy green salads Frozen vegetables
New industries and product types now involved
Listeria Environmental Monitoring
2
2
Typically has been a concern for low-moisture products Infant formula Spray-dried milk and whey
Recent Ritz and Goldfish crackers recalls
Chocolate
More recently: Nuts and nut butters Supplements (Kratom Powder) Breakfast cereals Dry pet foods and pet treats
Salmonella Environmental Monitoring

Seven Most Critical Components 1. Management Commitment
2. Determination of the Need
3. Risk Evaluation
4. The Sampling Plan
5. The Sampling Methods
6. Investigation and Corrective Actions
7. Data Management

Management Commitment
5
Corporate and facility management must understand and support the PEMP
Appropriate resources must be provided Employee training Employee time Sampling and testing costs
But even more important – support corrective actions and potential actions on product Sanitary design of equipment and facility – may
require significant $$$May have to put product on holdMay need to reject, destroy and/or reprocess
impacted product
Management Commitment

FSSC 22000: Management Responsibility Top management needs to be involved and committed to food safety
Ways to achieve: Routine summary reports
Red/yellow/green Dashboard
Communicate the importance of intensive EMP and aggressive corrective action
Cost of recalls, outbreaks, government actions
Use data to show secondary benefits Quality improvement/shelf life extension Sanitation efficiency with sanitary design Reduced customer complaints

Literature search
Trade associations
Government data
Internal data from exploratory surveys
Self-initiated Swabathons
Data from process validation studies
Listeriostatic
Listeriocidal
Trend: Multiple targets, more complicated

Risk Evaluation
11
Optimizing Data for Risk Evaluation
Properties of the product Intrinsic and extrinsic properties History
Where do pathogen reduction steps occur?
How complex is the production operation?
How often does sanitation occur?
Expert input
Not only whether or not to have PEMP, but how stringent How many samples taken at each sampling time? How often to sample?

The Sampling Plan
14
8
Every facility needs its own science-based sampling program
What to test for
Number of samples
Each processing area (hygienic zone)
Each sampling zone (1 – 4)
How often
Exactly where to sample
The Sampling Plan
15
Using Data for the Sampling Plan
Sampling locations are unique to the facility, product, process and equipment
Sampling sites and frequency are based on the risk evaluation and should change based on results over time
Available resources will create differences between facilities
Use data to set up the program
Use data to fine-tune and optimize
9
Using Data to Optimize
Should not be limited to sites easily cleaned & sanitized
Should include collection of residue from inaccessible or neglected niches
Seek and Destroy
Make a list of all zone 2 and 3 sites in the RTE area, choose from this list randomly but get complete coverage (example: every site sampled at least once per quarter) Computer program can help with this
Leave room for “creative” samples
Sample higher-risk and indicator sites more often
The Sampling Method
18
10
Data and the Sampling Method
Samples can be composited Not recommended for new programs or investigational sampling
Do not composite sponges from different sampling zones or lines
Compositing can complicate data management and slow corrective action
Does one technician find more positives than other technicians?
Investigation and Corrective Actions
20
11
Using Data to Initiate Investigations
A positive finding in Zone 1 or 2, or repeat findings in Zone 3 typically should trigger an investigation
Repeat findings in any zone may be sporadic but important clues Data analysis needs to be able to highlight
Where the positives occur can be critical Mapping!
Time lines
Other data (besides Listeria spp. positives) Construction, high volumes, formulation change, new employees,
weather, power failure, etc.
If its not documented it didn’t happen
History has a way of repeating itself
Some corrective actions require significant capital Use monitoring data to justify improvements
Do follow-up testing to ensure you were effective and that you “hold the gains”May add new sites to routine plan to make sure history does not repeat
Data and Corrective Actions
22
12
Investigation and Corrective Actions
Key Point - Persistence
Listeria monocytogenes illness and death linked to hotdogs. Eleven years later, exact strain from a connected plant linked to RTE turkey outbreak
Value of strain tracking – new form of data Hygiena RiboPrinter®, WGS, Rheonix Listeria PatternAlert™ Can help zero in on root cause House pets vs house pests Routine vs emergency
