Quantitative Microbial Risk Assessment Model to Estimate Exposure to Campylobacter from Consumption of Chicken in the United States
… a quantitative microbial risk assessment (QMRA) was conducted for boneless, skinless chicken breast meals prepared and consumed domestically in the contiguous United States. This QMRA model was developed with @RISK software (Palisade Corp., Ithaca, NY) and data inputs can be easily modified …

Rooftop Collected Rainwater Quality and Vegetation Impact: Field Work in Lagos, Nigeria, and the Related Experimental and Numerical Studies
… measures to enhance its quality. This study used QMRA to evaluate the health risk associated with bacterial contamination of roof-harvested rainwater (RHRW). To achieve this, the impact of some improvement techniques (such as first flush, sedimentation, and Household Treatment Techniques (HHTTs)) …

Quantifying uncertainty in pathogen removal, membrane integrity monitoring and health consequences in the treatment of drinking water
… we applied Quantitative Microbial Risk Analysis (QMRA) to examine the probability of infection by Cryptosporidium given that fibers may break on a daily basis. This later examination uses an uncertainty analysis of the levels of oocysts in source water bin classifications. The probability of fiber …

Impact of strain variability on the risk presented to chilled foods by non-proteolytic clostridium botulinum
… modular quantitative microbial risk assessment (QMRA) for a model dairy-based chilled dessert using a Monte Carlo simulation technique. The model considered four steps in product manufacture that either reduced or increased the hazard associated with non-proteolytic C. botulinum: spore load in …

Risk Assessment tool for water reuse - University of Cape Town as a case study
… Quantitative Microbial Risk Assessment (QMRA) already exists but can be complex, and relevant pathogen data is limited in South Africa. The existing risk assessment framework for irrigation with greywater in South Africa also lacks a detailed risk analysis. Lastly, no tools assess …

Assessment of health risk association with groundwater from Collins Chabane and Makhado Municipality of Vhembe District
… risk. Quantitative microbial risk assessment (QMRA) was carried out to determine the risks of infection and illness due to consumption of groundwater. The estimation of QMRA indices values suggest that school boreholes had higher risk of infection than household and communal sites. Highest risk …

Development of a Risk Assessment Model to Assess TMDL Implementation Strategies
… using Quantitative Microbial Risk assessment (QMRA) principles to translate source-specific (e.g. human, livestock) daily average concentrations of E.coli into a daily average risk of gastroenteritis infection was developed and applied to Pigg River, an impaired watershed in southern Virginia. …

Dishwashing Water Recycling System and Related Water Quality Standards for Military Use
… A quantitative microbial risk assessment (QMRA) was also performed based on exposure scenarios derived from literature data. As a result, a specific set of dishwashing water reuse standards for field analysis (simple, but accurate) was finalized as follows: turbidity (< 1 NTU), E. coli (< …

Power in numbers: quantitative microbial risk assessments of Salmonella in federally sampled ground meat products and the resulting impact of risk management strategies on public health
… Quantitative microbial risk assessment (QMRA) models that contextualized common handling, preparation, and consumption practices were developed to estimate annual illnesses attributable to the consumption of contaminated ground beef and ground pork in the US. Modifications to model …

Novel Approaches to Exposure Assessment and Dose Response to Contaminants in Drinking Water and Food
… a quantitative microbial risk assessment (QMRA) framework that follows a farm-to-fork model. Methods to ensure greatest microbial reduction include: employed intervention strategies at slaughter plants (i.e., water washing of beef carcass), improved cooking times and temperature methods at …

Disinfection of fresh produce contaminated by enteric viruses and their inactivation mechanisms
… a quantitative microbial risk assessment (QMRA) model was developed. Using this model, I estimated the health risks associated with consumption of rotavirus (RV)-contaminated fresh produce (‘Totem’ Belgian endive and ‘Red Russian’ kale), disinfected with either peracetic acid (PAA) or a …

Influence of natural and anthropogenic factors on Water, Sanitation, and Hygiene (WaSH)
… (2) Quantitative Microbial Risk Assessment (QMRA) to estimate the human health risk across different geographic location and exposure pathways for collected water samples, (3) investigate pathogen load/microbial profile between temporary settlement and recovered settlement two years after …

Disinfection of wastewater for reuse using microchannel plasma ozone generator
… and quantitative microbial risk assessment (QMRA) was used to compare microplasma ozonation versus chlorination to disinfect wastewater for landscape irrigational reuse. L. pneumophila, Giardia, and Cryptosporidium parvum were selected as the pathogens. Microplasma-based ozonation was …
