This book was released on 2004-06-19 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Provides the latest QMRA methodologies to determine infection risk cause by either accidental microbial infections or deliberate infections caused by terrorism • Reviews the latest methodologies to quantify at every step of the microbial exposure pathways, from the first release of a pathogen to the actual human infection • Provides techniques on how to gather information, on how each microorganism moves through the environment, how to determine their survival rates on various media, and how people are exposed to the microorganism • Explains how QMRA can be used as a tool to measure the impact of interventions and identify the best policies and practices to protect public health and safety • Includes new information on genetic methods • Techniques use to develop risk models for drinking water, groundwater, recreational water, food and pathogens in the indoor environment
Download or read book Microbial Water Quality Analysis of Bass and Piper Brooks in New Britain and Newington Connecticut written by Katelynn Elizabeth King and published by . This book was released on 2013 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Escherichia coli, enterococci, and fecal coliforms are bacteria that are commonly used to test water for fecal contamination. Water samples were collected biweekly for a nine-month period from six locations in Bass and Piper Brooks and were tested for each of the bacterial indicators listed above. Water samples were also collected to measure total suspended solids, turbidity, and pH. Temperature, dissolved oxygen, conductivity, and flow were measured in situ at each sampling location. The six sampling locations are part of the South Park River watershed which drains into the Connecticut River. Although these bacterial indicators can enter a watershed in mammalian or avian feces, they can enter in excessive amounts when sewage pipes are damaged or unmaintained, or from various other anthropogenic sources. The U.S. Environmental Protection Agency and the CT Department of Energy and Environmental Protection have water quality criteria that limit the amounts of these bacterial indicators in recreational waters. Although the streams that are being examined in this study are not used for recreational activities, they do run through suburban areas. Water quality analysis of local streams should be done in order to assess their ecological health. As environmental stewards it is the responsibility of humans to make sure that their actions are not contaminating the environment where they live. Relationships between variables were tested using correlation and regression analyses. There was a significant positive correlation that related temperature and enterococci, Escherichia coli, and fecal coliform. A significant negative correlation was found between dissolved oxygen and the three bacteria as well. Increased turbidity and total suspended solids can reduce visibility in the water which can put visual predators at a disadvantage. As particles from the water get lifted from the bottom or brought into the water column from ex situ sources, this can increase not only turbidity and total suspended solids, but also the pH of the water bodies.
Download or read book Encyclopedia of Food Safety written by and published by Academic Press. This book was released on 2013-12-12 with total page 2356 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the world’s growing population, the provision of a safe, nutritious and wholesome food supply for all has become a major challenge. To achieve this, effective risk management based on sound science and unbiased information is required by all stakeholders, including the food industry, governments and consumers themselves. In addition, the globalization of the food supply requires the harmonization of policies and standards based on a common understanding of food safety among authorities in countries around the world. With some 280 chapters, the Encyclopedia of Food Safety provides unbiased and concise overviews which form in total a comprehensive coverage of a broad range of food safety topics, which may be grouped under the following general categories: History and basic sciences that support food safety; Foodborne diseases, including surveillance and investigation; Foodborne hazards, including microbiological and chemical agents; Substances added to food, both directly and indirectly; Food technologies, including the latest developments; Food commodities, including their potential hazards and controls; Food safety management systems, including their elements and the roles of stakeholders. The Encyclopedia provides a platform for experts from the field of food safety and related fields, such as nutrition, food science and technology and environment to share and learn from state-of-the art expertise with the rest of the food safety community. Assembled with the objective of facilitating the work of those working in the field of food safety and related fields, such as nutrition, food science and technology and environment - this work covers the entire spectrum of food safety topics into one comprehensive reference work The Editors have made every effort to ensure that this work meets strict quality and pedagogical thresholds such as: contributions by the foremost authorities in their fields; unbiased and concise overviews on a multitude of food safety subjects; references for further information, and specialized and general definitions for food safety terminology In maintaining confidence in the safety of the food supply, sound scientific information is key to effectively and efficiently assessing, managing and communicating on food safety risks. Yet, professionals and other specialists working in this multidisciplinary field are finding it increasingly difficult to keep up with developments outside their immediate areas of expertise. This single source of concise, reliable and authoritative information on food safety has, more than ever, become a necessity
