Presenters: J. Baranyi, C. Pin, Y. Le Marc, A. Métris

Facilitator: L. Swift


The interface of IFR with the Industry

What Does the Network offer?

  • Access to the latest research into food issues
  • Seminars, conferences and workshops on topics you help define
  • A forum for national and international industry-science networking
  • Input to the development of research projects so they respond to industry needs
  • Science communication, newsletters, website with members-only features
  • Discussion of confidential issues relevant to individual members via F&HN Direct
  • Predictive Microbiology and Risk Analysis - Dr Jozsef Baranyi
  • Co-Product Exploitation- Dr Keith Waldron
  • Barriers - This Cluster has moved from events to research projects - Dr Steve Ring
  • Quality Throughout Shelf-Life - Dr Reg Wilson
  • Food Structure and Nutrition- Dr Pete Wilde
  • Allergy - Dr Clare Mills
  • Pathway to Personalised Nutrition - Dr Siân Astley
  • F&HN Direct - Prof Tim Brocklehurst, Head of Food & Health Network

Modular Training for the Industry: Predictive Microbiology for the Food Industry


  • To understand the concepts and practise of predictive modelling and risk assessment;
  • Via computer-based predictive modelling tools including ComBase;
  • To enable participants to use modelling tools in combination with the ComBase database and their own data to predict likely food safety scenarios that are relevant to their own needs.

Modular Training for the Industry: Predictive Microbiology for the Food Industry

3 years project; 2 workshops per year; next workshop 13th June 2007.

Raw data

Excel sheets

From data to ComBase:

Checking, modelling

Easy programming

Familier face

Browser, combined with predictions

Big capacity,

fast data retrieve

Access tables

combase system of data and programs
ComBase: system of data and programs
  • Excel version of the database: connected sheets (tables). This version is used for modelling, since maintenance programs and statistical, mathematical macros (for modelling purposes) are easily available for Excel.
  • Maintenance and modelling kit: Excel Visual Basic macros.
  • Access version of the database: The same tables as in Excel. After inputting, checking in Excel, the data are transferred to the Access, which has higher capacity and faster search speed.
  • ComBase Browser: Built on the Access version, navigates in the database in a user-friendly way.

e-COMBASE SUPPORTING INSTITUTES contributing to ca 20% of ComBase

SUPPORT. One record = one response (generally logcount curve) to one combination of conditions

data in combase v 4
Data in ComBase v.4

≈ 32 K records on pathogens; 2/3 full log-count curves

≈ 6 K on spoilage organisms; 1/3 growth/death rates

1 record = 1 observed response to a particular environment

combase roadmap
ComBase roadmap
  • ca 2-3,000 more records each year;
  • hosted at IFR, serves as a hub linked to related applications;
  • a main link isthe actual database that can be browsed on the ARS web site;
  • ComBase raw data on CD to be made available
  • Pathogen Modeling Program (PMP - US) and Growth Predictor (GP - UK) carry on (only prediction, no raw data);
  • - In 2007 : ComBase-PMP: Combined database and Predictive Microbiology Program

Unified improved predictive models in ComBase-PMP
