Water Research, 2020
In the more than 15 years since its introduction, quantitative microbial risk assessment (QMRA) has become a widely used technique for assessing population health risk posed by waterborne pathogens. However, the variation in approaches taken for QMRA in relation to drinking water supply is not well understood.

Variability in the recovery of a virus concentration procedure in water: Implications for QMRA
Water Research, 2015Methods for analysing water for viruses are known to have variable and relatively poor recovery efficiencies. Quantitative method recovery data are needed to correct virus enumeration results so that estimates of virus concentrations in surface waters for QMRA are not too low.

Practical applications of quantitative microbial risk assessment (QMRA) for water safety plans
Water Science and Technology, 2010 The absence of indicator organisms in drinking water does not provide sufficient guarantee for microbial safety. Therefore the water utilities are implementing water safety plans (WSP) to safeguard drinking water quality. Quantitative microbial risk assessment (QMRA) can be used to provide objective quantitative input for the WSP.

A QMRA Model for Salmonella in Pork Products During Preparation and Consumption
Risk Analysis, 2016As part of a quantitative microbiological risk assessment (QMRA) food chain model, this article describes a model for the consumer phase for Salmonella‐contaminated pork products. Three pork products were chosen as a proxy for the entire pork product spectrum: pork cuts, minced meat patties, and fermented sausages.

Applying QMRA and DALY to assess health risks from river bathing
International Journal of Hygiene and Environmental Health, 2016To estimate the health impact of bathing in urban river waters a two-step risk assessment was conducted using the example of the Ruhr River in North-Rhine Westphalia (Germany). The risk of acquiring gastrointestinal illness (GI) due to bathing in the Ruhr River was the focus of this analysis.

A Critical Review of Applications of QMRA for Healthy and Safe Reclaimed Water Management
Environmental Modeling & Assessment, 2021Reclaimed water use is being propounded as the best alternative source to address water demand concerns. Apprehensions exist concerning the microbial risks to the environment and public health. However, there is a growing interest in the risk assessment approach that can assimilate scientific and statistical programs to predict microbial risks in ...

Journal of Neuroimaging, 2023
ABSTRACT Background and Purpose The relationship between the degree and location of vertebrobasilar stenosis and QMRA distal-flow status is uncertain. Our aim was to investigate the relationship between QMRA distal-flow status with degree and location of vertebrobasilar stenosis.

Incorporating method recovery uncertainties in stochastic estimates of raw water protozoan concentrations for QMRA [PDF]
Journal of Water and Health, 2007 The impact of incorporating recovery data on protozoan concentration estimates was investigated for Cryptosporidium and Giardia using a large dataset (n=99) of [oo]cyst assay results with paired recovery estimates. Stochastic [oo]cyst concentration was estimated using three approaches: I – no availability/consideration of recovery, II – limited ...

QMRA-based reliability analysis to assess the performance of an ultrafiltration plant
Journal of Water Supply: Research and Technology-Aqua, 2011In the drinking water treatment industry, it is becoming increasingly important to evaluate the reliability of different water treatment processes. This paper extends the use of quantitative microbial risk assessment (QMRA) as part of a reliability analysis, to assess the capacity of alternative water treatment technologies to minimize risk of ...
