A growing beneficial reuse of biosolids in agriculture has led to concerns about potential contamination of water resources and the food chain. In order to comprehend the potential risks of transmission of diseases to the human population, an advanced quantitative risk assessment is essential. This requires good quantitative data which is currently limited due to the methodological limitations. Consequently, further development and standardization of methodologies for the detection, enumeration… Expand
Biosolids: Human Health Impacts
TLDR
The risk from pathogens can be managed through appropriate treatment of the biosolids and suitable management practices that minimize contact with susceptible members of the community. Expand
Review: Indicator bacteriophages in sludge, biosolids, sediments and soils.
TLDR
There is a need for improved and standardized methodologies for bacteriophage extraction, detection and enumeration in solids, and somatic coliphages show up as excellent complementary indicators for the prediction of pathogenic viruses in Solids. Expand
Assessment of the Accuracy of A Method Used for Quantification of Ascaris Eggs in Sewage Sludge
The application of sewage sludge on arable and grassland soils is dependent on the assurance that the concentrations of pathogens present in the biosolids do not pose health risks to eitherExpand

TLDR
Identifying specific genetic markers including protein, lipid, and metabolites using multiomics approach could be utilized for cheap, rapid, sensitive, specific and point of care detection tools for helminth ova and larva in the wastewater. Expand
Can manuka (Leptospermum scoparium) antimicrobial properties be utilised in the remediation of pathogen contaminated land
TLDR
Water extracted manuka components significantly inhibited an Escherichia coli lux biosensor, as well as inhibited the growth of Salmonella typhimurium, E. coli 0157, Clostridium perfringins, Campylobacter jejuni and Listeria monocytogenes, indicating potential for the use of manuka in the rehabilitation of microbial contaminated sites.

Pathogens and indicators in United States Class B biosolids: national and historic distributions.
TLDR
In general, the bacterial indicators total and fecal coliforms decreased from the 1980s to present, illustrating that the Part 503 Rule has been effective in reducing public exposure to pathogens relative to 17 yr ago. Expand
Persistence of bacterial indicators and zoonotic pathogens in contaminated cattle wastes
TLDR
Thoughtful design of manure storage infrastructure is critical to prevent spills and over-topping of an open structure, as the documented overload situation seems to lay the basis for an ongoing environmental contamination by enteric organisms and opportunistic pathogens circuit faecal-oral route. Expand
Determining pathogen and indicator levels in class B municipal organic residuals used for land application.
TLDR
High concentrations of enteric pathogens (e.g.,, , and HAdV) are present in biosolids throughout the United States, and microbial densities found can further assist management and policymakers in establishing more accurate risk assessment models associated with land application of Class B biosOLids. Expand
Removal of pathogenic bacteria from sewage-treated effluent and biosolids for agricultural purposes
The reuse of treated sewage for irrigation is considered as an important alternative water source in the new water management strategy of the countries that face a severe deficiency of waterExpand
Human-specific bacteriophages in sediments : a novel approach to waterborne hazard identification
TLDR
The findings suggest that the application of low-cost monitoring approaches to analyse river sediments may not only provide a better assessment of dominant pollution sources than grab samples of overlying water, but that they may also provide a a better indication of potential risks to health from human enteric viruses.

TLDR
It was concluded that adenoviruses and hepatitis A virus are the most thermally resistant viruses and can survive for prolonged periods in the environment. Expand
Survival of pathogenic and indicator bacteria in biosolids applied to agricultural land
TLDR
Reduced accessibility for grazing livestock by soil incorporation, together with the time taken for normal pasture establishment practices, and the limited pathogenicity of the vast majority of salmonellae present in biosolids may significantly reduce the risk of spread of these organisms to the human food chain. Expand
Monitoring of bacterial and parasitological contamination during various treatment of sludge.
TLDR
The aim of this study was to determine the impact of various sludge treatments on 2 types of pathogens (Salmonella and nematode eggs) and the levels of micro-organisms that indicate faecal contamination. Expand
Parasitological Contamination of Urban Sludge Used for Agricultural Purposes
Sludge re-use in agriculture has increased in many countries, but this practice must be associated with a knowledge of the pathogens present in these sludges. The aim of this study was to determineExpand
Emerging parasite zoonoses associated with water and food.
TLDR
Robust, efficient detection, viability and typing methods are required to assess risks and to further epidemiological understanding, and global sourcing of food, coupled with changing consumer vogues, can increase the risk of foodborne transmission. Expand
Preliminary testing of a rapid coupled methodology for quantitation/viability determination of helminth eggs in raw and treated wastewater.
TLDR
A vital staining procedure was developed and validated, and it was coupled with two rapid quantitative procedures previously assessed, permitting the determination of the total number of helminth eggs and, simultaneously, the viable and non-viable fraction. Expand
Sanitation and disease: Health aspects of excreta and wastewater management
TLDR
This book is intended for the wide spectrum of professionals concerned with sanitation and public health and contains twenty eight chapters, each describing the environmental properties of a specific excreted pathogen or group of excreting pathogens and the epidemiology and control of the infections these pathogens cause. Expand
Potential Regrowth and Recolonization of Salmonellae and Indicators in Biosolids and Biosolid-Amended Soil
TLDR
Overall, it is concluded that the use of concrete-lined beds created a situation in which moisture added as rainfall accumulated in the beds, promoting the growth of fecal coliforms and salmonellae added from external sources. Expand
Validity of the Indicator Organism Paradigm for Pathogen Reduction in Reclaimed Water and Public Health Protection
TLDR
Monitoring a suite of indicator organisms in reclaimed effluent is more likely to be predictive of the presence of certain pathogens, and a need for additional pathogen monitoring in reclaimed water in order to protect public health is suggested by this study. Expand
