Book Description
In the past decade there has been a rapid increase in waterborne outbreaks of disease associated with viral and protozoan agents, normally in drinking waters that were found to be microbially safe using the Coliform Index.For nearly a quarter of a century indicator organisms, in particular the coliform group, have been used to ensure the microbial

Book Description
This book examines, in both a current and historical context, water-related illness in the U.S. Emphasis is placed upon the transmission of infectious diseases through contaminated drinking water supplies and those deficiencies in water supply systems which allow waterborne outbreaks to occur. Chapters have been included on the important etiologic agents responsible for waterborne outbreaks in the U.S., surveillance activities, regulations, water treatment to prevent the occurrence of waterborne outbreaks and procedures for investigating waterborne outbreaks. For completeness, discussion have been included on illnesses contracted by ingestion of contact with waters for bathing , swimming, or wading and chronic ingestion of low levels of chemical contaminants in drinking water; however, because of space limitations there are necessarily brief, and the reader is directed toward the provided references, which discuss these subjects in more depth.

Book Description
Written by a team of international experts, this third edition designed to guide public health personnel or teams in any country that investigates reports of alleged waterborne illnesses. The manual is based on epidemiologic principles and investigative techniques that have been found effective in determining causal factors of disease incidence. The guidelines are presented in the sequence usually followed during investigations and are organized so that an investigator can easily find the information needed in any phase of an investigation. The book services as a guide to: • Develop a waterborne disease surveillance and emergency operations program • Handle illness alerts and water-related complaints that may be related to illness • Interview ill persons, those at risk, and controls • Develop a case definition • Transport water specimens and clinical specimens • Trace sources of contamination • Identify factors responsible for contamination, survival of pathogenic microorganisms or toxic substances, and/or propagation of pathogens • Collate and interpret collected data • Report information about the outbreak This edition has been extensively updated. A section has been added on water not intended for drinking as a source of illness. The chapter on “collection and analysis of data” has been significantly expanded to explain how data is collected and used to suggest possible vehicles, routes, and agents. The book is designed to improve the quality of investigation of outbreaks and disease surveillance. The International Association for Food Protection is a non-profit association of food safety professionals. Dedicated to the life-long educational needs of its Members, IAFP provides Members with an information network through its two scientific journals (Food Protection Trends and Journal of Food Protection), its educational Annual Meeting, international meetings and symposia along with international interaction between food safety professionals.

Book Description
Recent and forecasted advances in microbiology, molecular biology, and analytical chemistry have made it timely to reassess the current paradigm of relying predominantly or exclusively on traditional bacterial indicators for all types of waterborne pathogens. Nonetheless, indicator approaches will still be required for the foreseeable future because it is not practical or feasible to monitor for the complete spectrum of microorganisms that may occur in water, and many known pathogens are difficult to detect directly and reliably in water samples. This comprehensive report recommends the development and use of a "tool box" approach by the U.S Environmental Protection Agency and others for assessing microbial water quality in which available indicator organisms (and/or pathogens in some cases) and detection method(s) are matched to the requirements of a particular application. The report further recommends the use of a phased, three-level monitoring framework to support the selection of indicators and indicator approaches.Â

Book Description
As the human population grows-tripling in the past century while, simultaneously, quadrupling its demand for water-Earth's finite freshwater supplies are increasingly strained, and also increasingly contaminated by domestic, agricultural, and industrial wastes. Today, approximately one-third of the world's population lives in areas with scarce water resources. Nearly one billion people currently lack access to an adequate water supply, and more than twice as many lack access to basic sanitation services. It is projected that by 2025 water scarcity will affect nearly two-thirds of all people on the planet. Recognizing that water availability, water quality, and sanitation are fundamental issues underlying infectious disease emergence and spread, the Institute of Medicine held a two-day public workshop, summarized in this volume. Through invited presentations and discussions, participants explored global and local connections between water, sanitation, and health; the spectrum of water-related disease transmission processes as they inform intervention design; lessons learned from water-related disease outbreaks; vulnerabilities in water and sanitation infrastructure in both industrialized and developing countries; and opportunities to improve water and sanitation infrastructure so as to reduce the risk of water-related infectious disease.

Book Description
This text prepared by an international group of experts addresses the 'heterotrophic plate count' test which is widely used in drinking-water assessment: what it detects (and what it does not detect) its direct and indirect health significance and its use in the safety management of drinking water supplies. It includes the consensus statement from an expert review meeting and takes account of the presentations and posters at an international conference on the theme co-sponsored by WHO and NSF-International. It provides valuable information on the utility and the limitations of HPC data in the management and operation of piped water systems as well as other means of providing drinking water to the public. It is of particular value to piped public water suppliers and bottled water suppliers manufacturers and users of water treatment and transmission equipment and inline treatment devices water engineers sanitary and clinical microbiologists and national and local public health officials and regulators of drinking water quality. ...The book will be of great value to the piped public water suppliers bottled water suppliers manufacturers users of water treatment and transmission equipment and online treatment device makers water supply engineers sanitary engineers clinical and water microbiologists national and local public health officials and regulators of drinking-water quality. - Indian Journal of Medical Research

Book Description
Environmental mycobacteria can be found in diverse environments around the world, some of which have the ability to infect animals, birds and humans and have evolved mechanisms by which they can invade and grow within host cells, the pathogenic environmental mycobacteria (PEM). Although the diseases caused by these organisms have been known for many years, it is only recently that the potential significance of PEM as a waterborne pathogen has been appreciated. This publication discusses current knowledge about the distribution of PEM in water and other parts of the environment, the routes of transmission that lead to human infection, the most significant disease symptoms that can follow infection, methods of analysis and detection, the control of PEM in drinking-water and the assessment and management of risks.

Book Description
Coliforms are widely used as indicators of water quality and sanitary status, and levels are regulated as standards and legislation in many jurisdictions. The group of organisms known as coliform bacteria are commonly used to gauge quality and potential for health risk of potable and recreational waters, and are stimulated in water quality standards and legislation of many jurisdictions worldwide. The contents of this book includes an overview about the involvement of biofilms in waterborne diseases; currently employed methods of analysis for coliform bacteria; the testing of coliformic bacteria for water departments using automated sampling and analysis; the prevalence of E.coli outbreaks linked to the consumption of certain products; and finally, a review of the sources of coliform bacteria in freshwaters.
