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, dsiedenburg@foodprotection.org, for more information.

2023 Board Response to Recommendations
  1. We are writing to request your consideration in approving a change to the Microbial Modeling and Risk Analysis PDG, as discussed during our last Professional Development Group (PDG) meeting in Toronto. The PDG membership voted overwhelmingly in favor of expanding the scope of this group by renaming it to Modeling and Risk Analysis PDG, over 80% of PDG members agreed to this name change, with a strong turnout of over 83% participation. This change will allow the PDG to apply its expertise beyond microbial hazards to other areas like chemicals. Given this PDG's specialized knowledge in modeling and risk analysis, we believe broadening its purview will provide value. On behalf of the PDG, we kindly ask that you formally consider and approve this name change at the upcoming board meeting to align with the group's expanded focus. The PDG leadership is confident this change will enable the group to better serve the organization and its members.

    Board Response: Approved.

2017 Board Response to Recommendations
  1. 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

  2. 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.

  3. 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
  1. Recommend to the Board that Bala Kottapalli be approved as the Vice Chair.

    Board Response: Agree

  2. 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.

  3. 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
  1. 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.

Webinars

  • Cronobacter in the Spotlight: New Insights Into a Known Organism

    Organized by: ILSI Europe, the Low Water Activity Foods PDG, Microbial Modelling and Risk Analysis PDG, and the International Food Protection Issues PDG

    Description: Cronobacter spp. is generally known to survive for long times in dry environments and can also form biofilms. Due to these characteristics the genus is ubiquitous in the environment, and has been isolated from different sources: water, soil, dust, cereals, animal products, herbs, spices and others. Cronobacter spp. (formerly known as Enterobacter sakazakii) was also identified as causative agent in foodborne outbreaks, esp. leading to severe infections, and even death, in infants. Since the majority of cases are in neonates and even premature neonates, the main food product involved is powdered infant formula for babies of 0-6 months. The organism is very robust in surviving dry conditions and is even more difficult to control in dry factory environments than Salmonella. The persistence of these organisms also led to re-occurring outbreaks, fortunately not frequently, but consistent. In this webinar, we will start with a short introduction to the organism and then discuss more details, which are relevant for Cronobacter spp. controls, with an expert panel on subjects like: epidemiology, ecology, persistence, sampling, detection and identification methods, microbiological criteria, and preventive measures. The audience is invited to send in questions beforehand.

    Learning Objectives:

    • Epidemiology, Ecology, Persistence, Sampling, Detection and Identification Methods
    • Microbiological Criteria
    • Preventive measures

  • IAFP's Software Fair Series Part 2 - USDA Integrated Pathogen Modeling Program (IPMP)

    Organized by: The Microbial Modeling and Risk Analysis PDG and the International Committee of Predictive Modeling in Food (ICPMF)

    This series of Software Fair webinars aim to spread knowledge about the capacity and usefulness of these tools in industrial food safety and quality applications. The Software Fair webinars have the objective to disseminate the benefits of predictive microbiology, elaborate on its practical principles, and pave the way for the effective use of user-friendly tools; encompassing predictive modeling background in solving practical industrial (e.g., safe product formulations, shelf-life determination, etc.) and/or regulatory-relevant case studies (e.g., exposure assessment, compliance with microbiological criteria, etc.), in a more routine base. It is intended that each webinar presents a brief description of the capabilities of the existing tool(s), and practical case studies or applications; followed by answers to questions/comments from the audience.

    Part 2: Integrated Pathogen Modeling Program (IPMP) is a family of Windows-based desktop data analysis and prediction tools specifically developed for predictive microbiology research and application. The tools are designed to analyze individual isothermal growth and survival curves for primary models and the effect of temperature (secondary models) and also for one-step kinetic analysis that combines both primary and secondary models to minimize the residual errors globally. Integrated Pathogen Modeling Platform is a new online data analysis and prediction tool that incorporates the features and functionalities of desktop applications but is specifically designed for dynamic prediction of the growth and survival of foodborne pathogens throughout the supply chain.

  • Software Fair Series Part 1 - Bioinactivation & Biogrowth

    Organized by the IAFP Microbial Modeling and Risk Assessment PDG and the ICMPF Committee
    Sponsored by the IAFP Foundation

    Looking for the best fit for your microbiology data? bioinactivation & bio growth can find it for you.

    • Model fitting of growth (biogrowth) or inactivation (bioinactivation) data obtained under isothermal or dynamic conditions, using one-step or two-step approaches.
    • Calculation of predictions as deterministic curves or stochastic intervals (with parameter uncertainty).
    • Possibility to select between a large variety of models commonly used in predictive microbiology (Baranyi model, Weibull model, Cardinal models...).

    Available in two Open Access interfaces: a user-friendly web application, and an R package.

    Bioinactivation is an Open Source online tool for modelling microbial inactivation (https://foodlab-upct.shinyapps.io/bioinactivation4/) using the principles of predictive microbiology. It provides food scientists from academia, industry and regulatory agencies with a user-friendly interface to common tasks for the development and application of microbial inactivation models. It can be used to estimate the kinetic parameters from microbial inactivation data gathered under isothermal (using either a one-step or two-step approach) or dynamic conditions. It also includes functions for making predictions under isothermal or dynamic conditions, with the possibility of including parameter uncertainty (resulting in prediction intervals). Besides these prediction and model fitting tools, it includes additional features to aid in the analysis (residual plots to evaluate the goodness of the fit, statistical analyses, time to reach a given microbial count…). The calculations are based on mathematical models commonly used in predictive microbiology (Bigelow, Weibull, Geeraerd…), giving the user the possibility to alternate between them. The modules included in bioinactivation can be used to characterize the microbial response and compare between different treatment conditions, as well as to support microbial risk assessment and process design.

    Bioinactivation is entirely Open Source and transparent. The calculations are based on the bioinactivation package for R, available in CRAN (https://cran.r-project.org/package=bioinactivation) and GitHub (https://github.com/albgarre/bioinactivation). The code used to build the web application is also openly available in GitHub (https://github.com/albgarre/bioinactivation4).

    Biogrowth is a tool for modeling microbial growth based on predictive microbiology freely available online (https://foodmicrowur.shinyapps.io/biogrowth/). It serves as a user friendly-interface for scientists from academia, industries and regulatory agencies to advanced mathematical tools to describe microbial growth. It implements modules to fit growth models to data gathered under isothermal or dynamic conditions. It can also be used to fit a single model to data gathered under different environmental conditions (global fitting) or to estimate the cardinal growth parameters from a set of growth rates. Biogrowth can also be used to predict microbial growth under isothermal or dynamic conditions, with the possibility to include the effect of parameter uncertainty (resulting in prediction intervals). Furthermore, it includes several tools to aid in the analysis (statistical analyses, residual plots, time to reach a target microbial count…). The users can choose for model fitting or prediction among a variety of models commonly used in predictive microbiology (Baranyi, modified-Gompertz, Ratkowsky, Cardinal…). Therefore, the tools included in biogrowth can aid in the characterization of microbial growth kinetics, as well as to support shelf life estimation and microbial risk assessment.

    As well as bioinactivation, Biogrowth is entirely Open Source and transparent. The calculations are based on the biogrowth package for R, available in CRAN (https://cran.r-project.org/package=biogrowth) and GitHub (https://github.com/albgarre/biogrowth). The code used to build the web application is also openly available in GitHub (https://github.com/albgarre/biogrowth_web).

  • Data Science in the Food Industry

    Food Safety is one of the main challenges of the agri-food industry expected to be addressed in an environment of tremendous technological progress, where consumers’ lifestyles and preferences are in a constant state of flux. Food chain transparency and trust are drivers for food integrity control and also for improvements in efficiency and economic growth. Similarly, the circular economy has great potential to reduce wastage and improve the efficiency of operations in multi-stakeholder ecosystems. Throughout the food chain cycle, all food commodities are exposed to multiple hazards, resulting in a high likelihood of contamination. Such biological and/or chemical hazards may be naturally present at any stage of the food production, accidentally introduced or fraudulently imposed, putting at risk consumers’ health and their faith in the food industry. Nowadays, a massive amount of data is generated not only from the next-generation's monitoring food safety systems and along the entire food chain (primary production included), but also from IoT, media and other devices, which should be used for the benefit of society. The scientific discipline of "Data Science" should be considered as the vital player of driving forces to make this possible.

  • The Challenge of Conducting Challenge Tests

    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

    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

    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)
    https://www.sciencedirect.com/journal/international-journal-of-food-microbiology/vol/287/suppl/C

    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.

    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.
