Tutorial
Predictive Microbiology Information Portal (PMIP) contains three major sections which provide an access to predictive models for foodborne pathogens, relevant regulatory policies and guidelines, and microbial data related to pathogenic and spoilage microorganisms in a wide variety of food products. The predictive models are mainly from the Pathogen Modeling Program (PMP) of ERRC-ARS-USDA, and currently 15 models are in the portal. The main sources of rules/regulations are links to USDA-FSIS and FDA websites. The microbial growth data are from Combase, which contains about 40,000 data points. It is a relational database that is jointly developed and maintained by the Food Research Institute of UK, ARS-USDA, and the Center of Excellence for Food Safety, Australia. The portal provides a searchable function that the users can use to obtain specific information that is of interest to them. The tutorial provides brief instructions and examples on how to navigate the portal and retrieve necessary information.
To Learn about Predictive Microbiology
|
|
- Go to PMIP home page.
- Select “Overview of Predictive Microbiology.”
|
|
|
- The overview contains information regarding the principles of predictive microbiology, model development and relevant information.
|
To Locate Resources
|
|
- Go PMIP home page.
- Select “Resource Locator.”
|
|
|
- Resource Locate submenu appears.
- Select “Advance Search.”
- Select from Rule/Regulation, Organism, Food Type, and Resource Type lists.
- Resource type, numbers of resources, and their sources appear.
- Select from “Source List” to list the information
|
|
|
- Resources appear at the bottom of Advance Search page.
- Select “More Info” or “Go To” to access the information.
|
|
|

To Search Microbial Growth Data in Combase
|
|
- Go to PMIP home page
- Select “Data,” and then “Combase.”
|
|
|
- At the bottom of Combase page, select “Search by organisms, food type and environmental conductions” or “Search by Source.”
|
|
|
- Under “Search by organisms, food type and environmental conditions,” select food type, organisms and conditions, and then input the range of temperature, pH, water activity (or NaCl) of interest.
- Select “Search.”
|
|
|
- Results appear in a table show the matched records.
- Select “View Summary” to view all matched records and sources.
- Select “View Detail” to view matched records and data one by one.
- Select “Download to CSV” to download data of matched records.
|
|
|
- “View Detail” shows data of matched records and related information. Navigate through each record by select at navigation menu.
|
To Use Predictive Models
|
|
- Go to PMIP home page
- Select “Models,” and then “Pathogen Modeling Program (PMP).”
|
|
|
- Select “PMP Tutorial” to learn about PMP or select “PMP models” to go models.
|
|
|
- Select “Model>>Bacterium” or “Bacteria >>Model.”
|
|
|
- “Bacteria >>Model” shows type of bacteria and associated growth or inactivation models.
- Select bacterium and model of interest.
|
|
|
- Input conditions, and select calculate growth rate.
- Predicted growth data appear in chart and numbers with lag and no lag perditions.
