News – 11-13 May : IAFP European symposium on food safety, Athens, Greece

On the application of the general principles of food hygiene, it is the responsibility of the Food Business Operators (FBO) to control microbial risks in foods. Therefore, the FBO shall conduct studies in order to investigate compliance with the criteria, and investigate the ability of microorganisms of concern to grow or survive in the product during the shelf-life under different reasonably foreseeable storage conditions. The Codex Alimentarius has served the worldwide development in food trade, providing guidelines and integrating a global Microbial Risk Assessment based on : (i) data from publications and databases, (ii) characterization of pathogens and spoilers, (iii) challenge-tests and predictive modeling.

It makes sense that:

  • The available data and the fitting accuracy shall be carefully reviewed, helping in design the challenge studies
  • The challenge-tests shall comply with internationally recognized Guidance Documents recognized by Regulation bodies
  • The cardinal values which help in predicting strains behavior shall be determined according to good laboratory practices and quality assurance procedures, providing accurate values with the related standard deviations
  • And the predictive modeling shall be carried out using calculators under quality assurance, using state-of-the art approaches.

Complementary to international databases such as Combase©, Sym’Previus application gathers the commonly used fitting and growth non growth boundaries but as well:

  • Growth simulation tool based on the Gamma concept enabling different scenario of storage and formulation conditions (Zwietering, 1992).
  • Inactivation simulation tool based on the lambda concept (Mafart’s group, 2002, 2005, 2012)
Sym’Previus allows tailor-made use of predictive microbiology for:

  • Optimise industrial data
  • Hazard identification
  • Food process optimisation or development
  • Food shelf-life determination
  • Fit experimental data
It includes:

  • 4 fitting modules
  • 4 simulations modules
  • Database with pathogen and spoilage characterized microrganism
  • Possibility to add your own microorganism characterized
Sym’Previus quality assurance

  • Experimental data are validated by a scientific committee
  • All predictive models are published in peer review journal

Sym’Previus in a nutshell

Modules based on stochastic approach In addition to fitting modules, Sym’Previus provides sophisticated simulation modules based on stochastic approach. The extent of input that can be entered, is adapted to most food industry issues. Advanced and exhaustive results support key decisions.
Available online Sym’Previus is fully available online. It can be accessed from anywhere. Updates instantly benefit all users as soon as they are released.
20+ microorganisms 20+ microorganisms chosen for their interest in biological food safety issues are preset (subscription required). Growth and heat inactivation model parameters have been acquired by means of reliable protocols applied to various strains. Custom microorganisms can be created knowing their biological values to be tested in simulations.
Optimized mathematical models Fast response time due to optimized mathematical models.
Save results and simulations Simulations and results are saved in a logged account. They can be searched on and reloaded at any time.
