Microbial risk assessment in heterogeneous aquifers: 2. Infection risk sensitivity

Sensitivity analysis in quantitative microbial risk assessment.

The occurrence of foodborne disease remains a widespread problem in both the developing and the developed world. A systematic and quantitative evaluation of food safety is important to control the risk of foodborne diseases. World-wide, many initiatives are being taken to develop quantitative risk analysis. However, the quantitative evaluation of food safety in all its aspects is very complex, ...

Infection transmission system models for microbial risk assessment.

Chemical risk assessments often focus on measuring exposure as if individuals were subject only to exogenous environmental sources of risk. For infectious diseases, exposure might not only depend on exogenous sources of microbes, but also on the infection status of other individuals in the population. For example, waterborne infections from agents such as Cryptosporidium parvum and Escherichia ...

Microbial food safety risk assessment

Microbial risk assessment: dose-response relations and risk characterization.

Characterizations of the risks associated with foodborne pathogens are dependent on the availability of information on the population's exposure to the biological agents. However, by itself, exposure data are insufficient to assess the public health impact of pathogenic microorganisms. This requires the availability of effective dose-response models. Successful development of models that descri...

Risk Assessment Terminology: Risk Communication Part 2

The paper describes the terminology of risk communication in the view of food safety: different aspects of risk perception (perceived risk, media triggers, the psychometric paradigm, fright factors and cultural determinants of risk perception) are described. The risk profile elements are illustrated in the manuscript: hazard-food commodity combination(s) of concern; description of the public he...
