Food Protection Trends - November/December 2019 - 550

Phenotypic characterization - virulence, stress response.
Clustering for virulence profile determination.
Cluster prevalence estimation - Poisson regression
model.

Main results:
Differentially expressed protein-coding virulence genes
from the variable region, primarily belonging to SPI-6, 7,
10-12, and 16-19.
Concluding remarks:
* Considerable inter- and intra-serovar heterogeneity
observed in virulence and stress-response profiles of
Salmonella allowed for clustering based on presence/
absence of specific virulence and stress response
genes.
* Application into forecasting models indicated clusterspecific temporal trends and seasonality.
IAFP 2019 accepted proposals for roundtables, special
event and symposia (Sponsored by MMRA PDG).
10 out of 13 proposals for symposia, roundtables or
workshop were accepted and listed as follows:
Topic title:
* Campylobacter, Health Impact, Performance Objectives and Effectiveness of Sampling Plans (Symposium, Primary Contact: Marcel Zwietering).
* Back to the Future: What Do Decision Makers Want to
Know or Need to Know about Managing Chemical Risks
in Foods? (Symposium, Primary Contact: Yuhuan
Chen).
* Challenges of Campylobacter Detection and Control
(Symposium, Primary Contact: Nabila Haddad/Heidy
Den Besten).
* Future Pains: Assessing the Long-term Consequences
of Foodborne Exposure to Microbial and Chemical
Hazards (Symposium, Primary Contact: Barbara
Kowalcyk).
* Water Re-use in Food Processing Industry. It's
Inevitable! (Symposium, Primary Contact: Elisabetta
Lambertini).
* Application of Principles of Failure Mode Effects
Analysis (FMEA) for Effective Verification and Implementation of Food Safety Plans (Symposium, Primary
Contact: Aaron Uesugi).
* Software Fair (Symposium followed by Special Event,
Primary Contact: Mariem Ellouze).
* Pushing the Ball Forward for Agricultural Water
(Workshop, primary Contact: Dan Stoeckel).
* Attributing Illnesses to Food Sources in the Face of
Uncertainty (Symposium, Primary Contact: Michael
Bazaco).
* A New Paradigm: Cutting Pathogens off at the Pass by
Understanding Their Evolution Dynamics (Symposium,
Primary Contact: Pushpinder Litt).

Food Protection Trends November/December

Roundtables, Symposia, Workshops and Webinars -
Ideas for 2020:
Proposal submission due on October the 1st, 2019.
i.
Re-cap symposia and workshops in 2018 proposed by members/sponsored by MMRA PDG.
* People do mention our sponsorships without
contacting. For symposia proposal sponsorships, please contact Bala and Panos. For
receiving PDG support, please be timely
with your request, the latest 48 hours before
closing. Some symposia with our PDG marked
as primary sponsored during submission do
not acknowledge the PDG in the final program.
Please indicate MMRA PDG sponsorship in
the submission process (if received support
from MMRA PDG).
ii.
Discussion on ideas for 2019: considering cuttingedge information not previously presented; international perspectives on various issues (Formats:
roundtables, technical symposia, pre-meeting
interactive workshops).
* Computational modelling (industry to be updated).
* Marcel: All aspects that need to be included (identify
flaws, proper assumptions, etc.) when performing
a QMRA or laboratory experiment, or paraphrasing
literature, or assumptions in statistical testing (webinar,
roundtable, symposia).
* Yuhuan: Machine learning, automation, how the new
trends/thinking may help us do QMRA, or show potential limitations - exploring in this area.
* Heidy: Variability estimation, approaches to calculate
variability make use of variability in decision making
and regulatory authorities.
* Tania Roberts: Interested in data issue from industry,
how do we create a more robust data system to use
data (sharing, confidentiality) - how do we handle.
* Yuhuan: Roundtable with 6 panel members on software tools for risk-based thinking, risk-reduction mindset, encompassing practical use of these tools.
* Bala encouraged proposers of symposia that were
rejected in 2019 to revise and re-submit their proposals for 2020.
* Member from Vietnam: QMRA between developed and
developing countries - possible webinar or online platform to discuss knowledge transfer on QMRA between
the above.
Proposal leads can contact other PDGs, and send in
before October 1st (and to the PDG before end of September if sponsoring is desired). The Chair/Vice Chair can
serve as a liaison(s) to other PDGs to strengthen the
symposium proposals and avoid overlapping - e.g., reach
out chemical and allergen PDG.
Webinars and other communications:
* Already two webinars were held in 2019.
a. How to Integrate - OMICS in Risk Assessment
(March 2019).
