Antimicrobial Resistance in the Environment

Antimicrobial Resistance in the Environment PDF Author: Patricia L. Keen
Publisher: John Wiley & Sons
ISBN: 0470905425
Category : Science
Languages : en
Pages : 634

Book Description
Examines effects of the environmental distribution of antimicrobial resistance genes on human health and the ecosystem Resistance genes are everywhere in nature—in pathogens, commensals, and environmental microorganisms. This contributed work shows how the environment plays a pivotal role in the development of antimicrobial resistance traits in bacteria and the distribution of resistant microbial species, resistant genetic material, and antibiotic compounds. Readers will discover the impact of the distribution in the environment of antimicrobial resistance genes and antibiotics on both the ecosystem and human and animal health. Antimicrobial Resistance in the Environment is divided into four parts: Part I, Sources, including ecological and clinical consequences of antibiotic resistance by environmental microbes Part II, Fate, including strategies to assess and minimize the biological risk of antibiotic resistance in the environment Part III, Antimicrobial Substances and Resistance, including antibiotics in the aquatic environment Part IV, Effects and Risks, including the effect of antimicrobials used for non-human purposes on human health Recognizing the intricate links among overlapping complex systems, this book examines antimicrobial resistance using a comprehensive ecosystem approach. Moreover, the book's multidisciplinary framework applies principles of microbiology, environmental toxicology, and chemistry to assess the human and ecological risks associated with exposure to antibiotics or antibiotic resistance genes that are environmental contaminants. Each chapter has been written by one or more leading researchers in such fields as microbiology, environmental science, ecology, and toxicology. Comprehensive reference lists at the end of all chapters serve as a gateway to the primary research in the field. Presenting and analyzing the latest findings in a field of growing importance to human and environmental health, this text offers readers new insights into the role of the environment in antimicrobial resistance development, the dissemination of antimicrobial resistant genetic elements, and the transport of antibiotic resistance genes and antibiotics.

Principles of Food Sanitation

Principles of Food Sanitation PDF Author: Norman G. Marriott
Publisher: Springer Science & Business Media
ISBN: 1475762631
Category : Technology & Engineering
Languages : en
Pages : 432

Book Description
Large volume food processing and preparation operations have increased the need for improved sanitary practices from processing to consumption. This trend presents a challenge to every employee in the food processing and food prepara tion industry. Sanitation is an applied science for the attainment of hygienic conditions. Because of increased emphasis on food safety, sanitation is receiving increased attention from those in the food industry. Traditionally, inexperienced employees with few skills who have received little or no training have been delegated sanitation duties. Yet sanitation employees require intensive training. In the past, these employees, including sanitation program managers, have had only limited access to material on this subject. Technical information has been confined primarily to a limited number of training manuals provided by regulatory agen cies, industry and association manuals, and recommendations from equipment and cleaning compound firms. Most of this material lacks specific information related to the selection of appropriate cleaning methods, equipment, compounds, and sanitizers for maintaining hygienic conditions in food processing and prepara tion facilities. The purpose of this text is to provide sanitation information needed to ensure hygienic practices. Sanitation is a broad subject; thus, principles related to con tamination, cleaning compounds, sanitizers, and cleaning equipment, and specific directions for applying these principles to attain hygienic conditions in food processing and food preparation are discussed. The discussion starts with the importance of sanitation and also includes regulatory requirements and voluntary sanitation programs including additional and updated information on Hazard Analysis Critical Control Points (HACCP).

Advanced Oxidation Processes for Water and Wastewater Treatment

Advanced Oxidation Processes for Water and Wastewater Treatment PDF Author: Simon Parsons
Publisher: IWA Publishing
ISBN: 1843390175
Category : Science
Languages : en
Pages : 370

Book Description
The suitability of Advanced Oxidation Processes (AOPs) for pollutant degradation was recognised in the early 1970s and much research and development work has been undertaken to commercialise some of these processes. AOPs have shown great potential in treating pollutants at both low and high concentrations and have found applications as diverse as ground water treatment, municipal wastewater sludge destruction and VOCs control. Advanced Oxidation Processes for Water and Wastewater Treatment is an overview of the advanced oxidation processes currently used or proposed for the remediation of water, wastewater, odours and sludge. The book contains two opening chapters which present introductions to advanced oxidation processes and a background to UV photolysis, seven chapters focusing on individual advanced oxidation processes and, finally, three chapters concentrating on selected applications of advanced oxidation processes. Advanced Oxidation Processes for Water and Wastewater Treatment will be invaluable to readers interested in water and wastewater treatment processes, including professionals and suppliers, as well as students and academics studying in this area. Dr Simon Parsons is a Senior Lecturer in Water Sciences at Cranfield University with ten years' experience of industrial and academic research and development.
