Welcome to the CAMRA Microbial Risk Assessment Wiki (CAMRAwiki)
This website is dedicated to delivering the most up-to-date information and knowledge which CAMRA has developed in the QMRA field. Out future goal is to become a central repository for QMRA knowledge and data. It is our intent to be a peer reviewed wiki where if users or visitors wish to add to our wiki they are welcome to submit their proposed addition to email@example.com for one of our experts to review for inclusion to the wiki.
This site is intended to provide easy instruction about QMRAs as well as data to perform your own QMRAs.
Links on the left allow you to access pathogen information that CAMRA has compiled. Each pathogen has a Pathogen Safety Data Sheet (PSDS) that gives a brief overview of the hazard and its associated risks.
The four key areas of microbial risk assessment (MRA) are the following:
- Hazard identification: The hazard identification is both identification of the microbial agent and the spectrum of human illness and disease associated with the specific microorganism.
- Dose response assessment: The dose response analysis provides a quantitative relationship between the likelihood of adverse effects and the level of microbial exposure. Without knowing how different levels of the stressor affect the individual a sizable portion of quantified risk estimate will not be possible. The dose response assessment phase is arguably the most important phase in the QMRA paradigm.
- Exposure assessment: The exposure assessment identifies affected population, determines the exposure pathways and environmental fate and transport, calculates the amount, frequency, length of time of exposure, and estimates dose or distribution of doses for an exposure.
- Risk characterization: The risk characterization Integrates dose-response analysis and exposure assessment to estimate the magnitude of risk, uncertainty and variability of the hazard.
- QMRA Tools: A variety of QMRA tools begin as simplistic tools essentially established and tested Microsoft Excel spreadsheets. Some QMRA tools are being developed as standalone computer applications.
- Environmental Infection Transmission Systems (EITS): This work advances the conceptual framework for the science of environmental mediation of person to person transmitted infections by stochastic processes.
- Risk communication
