How to Join
Involvement in committees and professional development groups (PDGs) offers Members the opportunity to share a wealth of knowledge and expertise. Members of committees and PDGs are the architects of the Association structure. They plan, develop and institute many of the Association's projects, including workshops, publications and educational sessions. Technical challenges facing the food safety industry are discussed, examined and debated. Members may volunteer to serve on any number of committees or PDGs that plan and implement activities to meet the Association's mission.
Membership on a PDG is voluntary (not by appointment) and may vary from year to year.
IAFP Members can manage their PDG involvement by logging in to the IAFP Web site. At the Member Dashboard, click “Edit Profile.” Your profile has two tabs: Contact Info and Professional Info. Select the Professional Info tab and update the PDGs you would like to participate in. We highly recommend that you contact the PDG chairperson for each group to let them know you have joined their PDG.
Non-members can contact Dina Siedenburg, email@example.com, for more information.

student abstracts (to be presented as posters/technical
presentations in the forthcoming IAFP meeting) that will
be qualified by the judgment panel of the PDG for being
presented at the PDG.
Board Response: Agree.
2017 Board Response to Recommendations +
Recommend contacting firms like IBM who are working with the food industry on BIG data across the industry and finding a sway for them to summarize their findings through webinars, symposia or informal sessions.
Board Response: Agree, the Board encourages this PDG to proceed with this effort
The MMRA PDG again had big support to recommend that recordings of MMRA PDG webinars be made freely available for both ALL IAFP Members and Non-Members. It is especially the most generic subjects that would be good to broadly diffuse.
Board Response: The MMRA PDG again had big support to recommend that recordings of MMRA PDG webinars be made freely available for both ALL IAFP Members and Non-Members. It is especially the most generic subjects that would be good to broadly diffuse.
Recommend finding a way to fund webinars through the PDG for presentations that cannot be sponsored by a commercial third party, due to the nature of the project (such as a study by a government agency or WHO/FAO). This would help make webinars freely available.
Board Response: The Board is open to optional funding of webinars.
2016 Board Response to Recommendations +
Recommend to the Board that Bala Kottapalli be approved as the Vice Chair.
Board Response: Agree
Webinars are a great way of promoting food safety to students, the developing world, small and medium enterprises and other interested parties, and also a good marketing tool for IAFP. Currently, the recordings are only available for members and the webinar itself is freely available if it has as audience PDG members only. The MMRA PDG again had big support to recommend that recordings of MMRA PDG webinars be made freely available for both IAFP members and non-members. The PDG also recommends that webinars sponsored by the MMRA PDG be freely available to members of other IAFP PDGs. This could contribute largely to advancing food safety worldwide, but also improve marketing for new IAFP members.
Board Response: All IAFP members have access to the Webinars including members of other PDGs. Membership in IAFP is economically priced and viewing Webinars is a benefit of IAFP Membership.
Recommend the Board consider providing electronic addendum for scientific papers published in Journal of Food Protection. Other journals such as the SRA Risk Analysis, IJFM and AEM provide such service so providing electronic addendum to JFP will stimulate people in this domain to submit more papers.
Board Response: Under the new, JFP Online system, authors will be able to submit supplemental information with their manuscript in the format desired for posting upon finalization of their article.
2015 Board Response to Recommendations +
Webinars are a great way of promoting food safety to students, the developing world, small and medium enterprises and other interested parties, and also a good marketing tool for IAFP. Currently the recordings are only available for members and the webinars itself freely available if it has as audience PDG members only. The MMRA PDG recommends that recordings of MMRA-PDG webinars be made freely available again (as was in the past) for both IAFP members and non-members. The PDG also recommends that webinars sponsored by the MMRA PDG be freely available to members of other IAFP PDGs.
Board Response: Webinars are available to IAFP Members as a member benefit and serve as an incentive to those who are not members to become an IAFP Member. Membership rates are kept extraordinarily low so that it is possible for any interested individuals to be an IAFP Member.
2014 Board Response to Recommendations +
Recommend to the Board that Marcel Zwietering be the Vice Chair.
Board Response: Approved.
Recommend to the Board that the MMRA PDG mission statement be revised as follows: To facilitate communication on the topics of predictive modelling (PM) and microbial risk analysis (MRA), encourage research and data reporting methods to support PM and MRA, and promote their applications and use.
Board Response: Approved.

The Challenge of Conducting Challenge Tests
Sep 13, 2019
It is the responsibility of food business operators to take measures to ensure that food safety criteria are applicable throughout food production processes, food storage conditions and food preparation. In the case of ready-to-eat and/or perishable food which supports microbial growth, predictive microbiology, literature data or challenge test studies are performed to prove compliance to regulation. In the case a challenge test is deemed necessary, the webinar will provide guidance on how to conduct it properly, based on the recently published standard on challenge testing and the European technical guidance document. This will lead to greater confidence in the control of Listeria monocytogenes and thus to safer food.

Applying Behavioral Economics to Model the Threat of Food Fraud
Apr 16, 2019
Sponsored by: Battelle
Organized by: IAFP's Microbial Modelling and Risk Analysis PDG
Description: The food protection community is well-versed in applying mathematical modeling to estimate microbiological growth as part of assessing food safety hazards or estimating shelf life. In contrast, the application of mathematical modeling to estimate threat based on the behavioral trends is a less familiar, yet very relevant concept in food protection as food fraud incidents perpetrated by people rather than microbes impact both consumers and producers.
Behavioral economics' Utility theory, which has been used to predict trends ranging from consumer preference to terrorist threat, can be applied to proactively quantity the threat of food fraud to a supply chain based on a range of measurable ingredient characteristics. The concept of modeling human behavior and its application to food protection will be discussed and the specific use case of estimating food fraud will be presented in detail.

The Integration of Omics in Microbiological Risk Assessment
Mar 27, 2019
Sponsored by: ILSI Europe
Organized by: Microbial Modelling and Risk Analysis PDG
Description: Currently, with the possibilities to investigate microorganisms at molecular level, we are experiencing an exciting momentum in which we can exploit this information to better understand the ecology and physiology of foodborne pathogens. Even more intriguing is the possibility to integrate omics data into risk assessment schemes. It is expected that in the next future this will be used to better control pathogenic microorganisms in the food chain.
After a discussion forum (IAFP Europe 2015), a workshop at IAFP Europe 2016 (co-organized by ILSI Europe, IAFP and ICFMH) a special issue resulted:
Omics in MRA - the integration of omics in microbiological risk assessment
International Journal of Food Microbiology 287, Pages 1-40 (20 December 2018)
These papers have the goal to describe the state of the art and create the foundation for a constructive discussion on how to best use, integrate and exploit omics data in MRA. In this webinar the outcome of these paper will be presented.

Dose-Response for Listeria monocytogenes presented by Microbial Modelling and Risk Analysis (MMRA) Professional Development Group (PDG)
Jun 1, 2017
The relationship between the number of ingested Listeria monocytogenes cells in food and the likelihood of developing listeriosis is not well understood. Various dose-response models, based on animal models, outbreak data or epidemiological date are currently available. During this webinar, we’ll recall the specific difficulties in deriving a dose-response for Listeria monocytogenes and describing the various models that are currently developed and used. We’ll present the unique data FDA obtained from recent outbreaks and explain if and how they helped our knowledge of this dose-response.

Modeling Variability and Uncertainty in Risk Assessment: a Case Study of Salmonella in Low-water Activity Foods and its Use in Decision Making
Jun 8, 2016
Microbial Modelling and Risk Analysis Professional Development Group Presents: Modeling Variability and Uncertainty in Risk Assessment: a Case Study of Salmonella in Low Water Activity Foods and its Use in Decision Making. The presence, survival and heat resistance of Salmonella in low-water activity foods is affected by many factors including environmental, processing and those inherent to the pathogen. The estimated risk of salmonellosis from consumption of these products is influenced by these factors as well as consumption patterns, production volume and population numbers. Variability in the value of each factor affects the risk of illness whereas uncertainty in the knowledge of each factor affects the risk estimate. The aim of this webinar is to provide an overview of strategies for incorporating variability and uncertainty in quantitative risk assessment models for Salmonella in low-water activity foods and describe the utility of doing so for the decision maker.

The application of the Appropriate Level of Protection (ALOP) and Food Safety Objective (FSO) Risk-based Metrics in Food Safety Management
Jan 20, 2015
Risk-based metrics such as the ALOP and FSO have been formally adopted by Codex Alimentarius as a means of establishing a link between governmental public health policy and the management of safety in the food chain. Although this link is very much desirable for making food safety management transparent and quantifiable, the ALOP and FSO are not yet actively used as such by competent authorities, maybe due to difficulties to operationalize the metrics.

Distributions of microorganisms in food and their impact on food safety
Jan 31, 2013
Not much is known about how microorganisms are actually physically distributed in foods, yet these distributions determine the likelihood of a foodstuff to cause illness and the consequential public health burden. When food is sampled in an effort to reduce the risk of causing illness, the effectiveness of the sampling programme is also related to the spatial distribution of the microorganisms that are being sampled for.

Quantitative Assessment of the Microbial Risk of Leafy Greens from Farm to Consumption: Preliminary Framework, Data, and Risk Estimates
Jan 17, 2012
This presentation presents the findings from a project that was undertaken to relate what is known about the behavior of E. coli O157:H7 under laboratory conditions, and integrate this information to what is known regarding the 2006 E. coli O157:H7 spinach outbreak in the context of a Quantitative Microbial Risk Assessment (QMRA). The QMRA explicitly assumes that all contamination arises from exposure in the field, but the mechanism is unspecified. This QMRA model represents a preliminary framework that identifies available data and provides initial risk estimates for pathogenic E. coli in leafy greens. Important data gaps that were identified include retail storage times, correlations between storage time and temperature, determining the importance of E. coli O157:H7 in leafy greens lag time models, and validation of the importance of cross-contamination during the washing process.
