Workshop Description

Eleven new predictive models have recently been added to the USDA-ARS-Pathogen Modeling Program (PMP).  Last year, USDA-ARS assumed the responsibility for supporting ComBase, and building the platform for its continued success.  Accordingly, this workshop will give a hands-on update on the PMP and ComBase, a user-friendly interface to quickly retrieve microbial data for addressing their food safety needs.  As a first step, the presenter will give an overview of predictive modeling, and would cover topics, such as classes of microbial models, including discussion on underlying principles of modeling as well as the use and interpretation of the predictive models.  Attendees will learn the most important microbiological safety issues facing the food industry on a global scale, enhance and update knowledge of predictive microbiology, and learn to use the PMP and ComBase.  The attendees will understand how to locate and retrieve regulatory information as well as the predictive model that is applicable to a food product of their interest and the pathogen of concern.    

Specifically, the workshop will describe and demonstrate how the USDA-ARS-PMP and ComBase can be used to predict accurate estimates on growth, survival, and lethal effects of processing environments on foodborne pathogens; and how to determine compliance with regulatory performance standards.  Participants will be able to predict the outcome of a process, e.g., the number of log reduction, resulting from the processing conditions, e.g., residence time and temperature, and to predict for untested conditions.  Case studies demonstrating their application will be an integral part of the workshop.  By participating in this workshop, attendees will get familiar with the recent developments as well as will get a better understanding of how to use ARS modeling programs and ComBase to enhance the safety of our food supply.  All participants would need to bring their laptops to obtain hands-on experience and training for proper use of the software programs.  The workshop will close with an evaluation sheet to obtain feedback from attendees.
