Data Extent

ComBase: A Web Resource for Quantitative and Predictive Food Microbiology

ComBase includes a systematically formatted database of quantified microbial responses to the food environment with more than 65,000 records, and is used for:

  • Informing the design of food safety risk management plans
  • Producing Food Safety Plans and HACCP plans
  • Reducing food waste
  • Assessing microbiological risk in foods

The ComBase Browser enables you to search thousands of microbial growth and survival curves that have been collated in research establishments and from publications.

The ComBase Predictive Models are a collection of software tools based on ComBase data to predict the growth or inactivation of microorganisms as a function of environmental factors such as temperature, pH and water activity in broth.

Interested users can also contribute growth or inactivation data via the Donate Data page, which includes instructional videos, data template and sample, and an Excel demo file of data and macros for checking data format and syntax.
