Sensitivity analysis in quantitative microbial risk assessment
International Journal of Food Microbiology, 2000The 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.

Challenges of quantitative microbial risk assessment at EU level
Trends in Food Science & Technology, 2008Quantitative microbial risk assessment (QMRA) aims to model the fate of pathogenic micro-organisms along the food chain and the associated health risks. More importantly, it allows the a priori estimation of the impact on public health of interventions in the food chain.

Modeling Logistic Performance in Quantitative Microbial Risk Assessment
Risk Analysis, 2009In quantitative microbial risk assessment (QMRA), food safety in the food chain is modeled and simulated. In general, prevalences, concentrations, and numbers of microorganisms in media are investigated in the different steps from farm to fork.

Quantitative Microbial Risk Assessment of Pharmaceutical Products
PDA Journal of Pharmaceutical Science and Technology, 2016Monitoring of microbiological quality in the pharmaceutical industry is an important criterion that is required to justify safe product release to the drug market. Good manufacturing practice and efficient control on bioburden level of product components are critical parameters that influence the microbiological cleanliness of medicinal products ...

Quantitative risk assessment of microbial sampling effectiveness
Clinical Microbiology Newsletter, 2002Abstract Sampling as a means of assuring food safety can be analyzed by quantitative risk assessment. A computer simulation was performed in which liquid raw material with varying levels of contamination (−1 to −6 log CFU/ml) was converted into a food by a process that causes a mean log reduction of 5 log CFU/ml.

The Application of Quantitative Risk Assessment to Microbial Food Safety Risks
Critical Reviews in Microbiology, 1996Regulatory programs and guidelines for the control of foodborne microbial agents have existed in the U.S. for nearly 100 years. However, increased awareness of the scope and magnitude of foodborne disease, as well as the emergence of previously unrecognized human pathogens transmitted via the foodborne route, have prompted regulatory officials to ...

Quantitative microbial risk assessment for sustainable water resources
2021This thesis evaluates the microbiological health risks of using the sustainable water resources roof-harvested rainwater and reclaimed water. This research was accomplished by performing six tasks: 1) prioritizing pathogens for exploration; 2) conducting a screening study of opportunistic pathogens in rainwater tanks identified in task 1 in Brisbane ...

Marine Pollution Bulletin, 2020
Urban beaches are frequently impacted from multiple sources of fecal contamination. This along with high beach usage underscores the importance of appropriate management that protects swimmer health. The USEPA has enabled the use of QMRA as a tool for quantifying swimmer health risk and setting site-specific water quality objectives.

For the estimation of public health risk from exposure to pathogens, quantitative microbial risk assessment (QMRA) can be used. QMRA entails hazard identification, exposure assessment, dose response and risk characterisation. Here, QMRA is focussed on infection risks from exposure to water-borne pathogens due to drinking-water consumption ...

Quantitative Microbial Risk Assessment and Molecular Biology: Paths to Integration
Environmental Science & Technology, 2020Quantitative microbial risk assessment (QMRA) has now been in use for over 35 years and has formed the basis for developing criteria for ensuring public health related to water, food, and remediation, to name a few areas. The initial data for QMRA (both in exposure assessment and in dose response assessment) came from measurements using assays for ...
