Book excerpt: Although widely recognized as an important waterborne pathogen, Cryptosporidium spp. can also be transmitted by contamination of food. The same properties of this protozoan parasite that mean that water is an excellent transmission vehicle are also important for foodborne transmission. These include the low infective dose, the high number of oocysts that are excreted, and the robustness of these transmission stages. However, many more outbreaks of waterborne cryptosporidiosis have been reported than foodborne outbreaks. This is probably partly due to epidemiological tracing being much more difficult for foodborne outbreaks than waterborne outbreaks, and the number of persons exposed to infection often being fewer. Nevertheless, the potential importance of foodborne transmission is gradually being recognized, and a wide range of different foodstuffs have been associated with those outbreaks that have been recorded. Additionally, various factors mean that the potential for foodborne transmission is becoming of increasing importance: these include the growth of international food trade, a current trend for eating raw or very lightly cooked foods, and the rise in small-scale organic farms, where there the possibility for contamination of vegetable crops with animal feces may be greater.

The same properties of this protozoan parasite that mean that water is an excellent transmission vehicle are also important for foodborne transmission. These include the low infective dose, the high number of cysts that are excreted, and the robustness of these transmission stages. However, many more outbreaks of waterborne giardiasis have been reported than foodborne outbreaks. This is probably partly due to epidemiological tracing being much more difficult for foodborne outbreaks than waterborne outbreaks, and the number of persons exposed to infection often being fewer. Nevertheless, the potential importance of foodborne transmission is gradually being recognized, and a wide range of different foodstuffs have been associated with those outbreaks that have been recorded. Additionally, various factors mean that the potential for foodborne transmission is becoming of increasing importance: these include the growth of international food trade, a current trend for eating raw or very lightly cooked foods, and the rise in small-scale organic farms, where there the possibility for contamination of vegetable crops with animal faeces may be greater.

Available in PDF, EPUB and Kindle. Book excerpt: Domestic animals contaminate recreational waters and drinking-water sources with excreta and pathogens; but this threat to public health is inadequately understood and is insufficiently addressed in regulations. More than 85% of the world’s faecal wastes is from domestic animals such as poultry, cattle, sheep and pigs. These animals harbor zoonotic pathogens that are transported in the environment by water, especially runoff. However little information exists on health effects associated with exposure to this potential hazard to human health; and water standards focused on control of human fecal contamination do reflect the contribution of non-human fecal contamination to risk. Does compliance with current monitoring practices using microbial indicators provide protection against animal and bird sources of fecal contamination? Prepared with contributions from a group of international experts, Animal Waste, Water Quality and Human Health considers microbial contamination from domestic animal and bird sources and explores the health hazards associated with this microbial contamination and approaches to protecting public health. Animal Waste, Water Quality and Human Health will be of interest to regulators with responsibility for recreational waters, drinking water quality and water reuse; policymakers working in water quality, public health and agriculture; decision makers responsible for livestock management; and scientists and practitioners concerned with many affected subjects. Topics covered include: Credible waterborne zoonotic pathogens are discussed and ranked according to their potential hazard level. Each pathogen is described with regard to their sources, reservoirs, and infectivity. Faecal production rates of various domestic animals are discussed, alongside pathogen transmission in animal populations, pathogen prevalence in animals and “supershedders”. Transport of fecal indicator organisms and their episodic occurrence in catchments. Interventions for improving food safety and reducing production losses. The impact of interventions, e.g. enhanced attenuation and storage to prevent spills; benchmarking against best management practices to reduce diffuse source contamination. Models to inform design of farm-scale best management practices and the effectiveness of best management practices for attenuating pathogen transport within catchments. The complex nature of human exposure to zoonotic waterborne pathogens; including the relationships among livestock waste contamination, water impairment, zoonotic pathogens, and human infection and illness. Human exposure interventions include case studies that discuss eradicating disease in discharging populations, adding filtration to minimal treated water to reduce Cryptosporidium occurrence and UV disinfection of beach waters to reduce beach postings. Indicators, sanitary surveys and source attribution techniques; risk assessment of exposure to zoonotic pathogens, including an interactive risk comparison approach. A review of epidemiological studies that address the relationship between swimmer illness and exposure to waters contaminated by nonhuman fecal wastes. Economic evaluation of the costs and benefits associated with animal waste management and human health.

Book excerpt: 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.

This book was released on 2012-09-10 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.

This book was released on 2022-01-29 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The enteric protozoans Cryptosporidium spp. and Giardia duodenalis are the most common diarrhoea-causing protozoan parasites worldwide. Cryptosporidium spp. is a leading cause of diarrhoea morbidity and mortality in children younger than 5 years of age in poor-resource settings in sub-Saharan Africa and South Asia. Although infection by G. duodenalis is rarely a fatal condition, giardiasis is commonly associated with childhood growth faltering and cognitive impairment. Because of their significant socioeconomic impact, particularly in low-income countries, giardiasis and cryptosporidiosis joined the "Neglected Disease Initiative" launched by the World Health Organization in 2004. Both Cryptosporidium spp. and G. duodenalis are ubiquitous in the environment and can infect a wide range of hosts with different specificities, meaning that humans may acquire the infection via waterborne, foodborne, or zoonotic transmission. Recent advances in detection and molecular epidemiology have indicated that certain species/genotypes of Cryptosporidium and G. duodenalis have an expanded range of suitable hosts, suggesting that their transmission pathways are more intricate than previously thought, challenging our current notion of host specificities. Therefore, there is a clear need for more studies aiming at investigatingthat aim to investigate the frequency and molecular diversity of these parasites in humans, production and companion animals, and wildlife species. This information would be extremely useful to elucidate the transmission dynamics of cryptosporidiosis and giardiasis, and to investigate the exact contribution of zoonotic events to human infections.

Available in PDF, EPUB and Kindle. Book excerpt: In the relatively short period since Cryptosporidium was recognised as a human pathogen, and that it could be transmitted in water as well as directly between animals and people, it has been the subject of intense investigations. Its status as an opportunistic pathogen, especially in AIDS patients, and the lack of effective anti-cryptosporidial drugs have served to emphasise the public health importance of this organism. This has to some extent overshadowed the fact that Cryptosporidium is also an important pathogen of domestic animals and wildlife. In recent years, the application of molecular biology and culture techniques have had an enormous impact on our understanding of the aetiological agents of cryptosporidial infections and our ability to study the causative agents in the laboratory. As a consequence, a wealth of information and novel data has been produced during the last 3-4 years, particularly in the areas of taxonomy, biology, pathogenesis, epidemiology - particularly zoonotic and water borne transmission, and treatment. It is thus very timely to bring together in this book the international research community involved to review the major advances in research and identify the important research priorities for the future, thus enabling as wide an audience as possible to benefit from and share in this comprehensive look at Cryptosporidium and cryptosporidiosis.

Available in PDF, EPUB and Kindle. Book excerpt: Clearly linked to consumption of foods, beverages, and drinking water that contain pathogenic microbes, toxins, or other toxic agents, foodborne diseases have undergone a remarkable change of fortune in recent decades, from once rare and insignificant malaises to headline-grabbing and deadly outbreaks. Unquestionably, several factors have combined to make this happen. These include a prevailing demand for the convenience of ready-to-eat or heat-and-eat manufactured food products that allow ready entry and survival of some robust, temperature-insensitive microorganisms; a drastic reduction in the costs of air, sea, and road transportation that has taken some pathogenic microorganisms to where they were absent previously; an expanding world population that has stretched the boundary of human activity; and an ageing population whose weakened immune functions provide a fertile ground for opportunistic pathogens to invade and thrive. Given the diversity of causative agents (ranging from viruses, bacteria, yeasts, filamentous fungi, protozoa, helminthes, toxins, to toxic agents), and the ingenuity of pathogenic microbes to evolve through genetic reassortment, horizontal gene transfer, and/or random genetic mutation, it has become an enormous challenge to understand how foodborne agents are able to evade host immune defenses and induce diseases, and also to develop and apply innovative approaches for improved diagnosis, treatment, and prevention of foodborne diseases. Handbook of Foodborne Diseases summarizes the latest findings on more than 100 foodborne diseases and their causative agents. With contributions from international experts on foodborne pathogens, toxins, and toxic agents research, this volume provides state-of-the-art overviews on foodborne diseases in relation to their etiology, biology, epidemiology, clinical presentation, pathogenesis, diagnosis, treatment, and prevention. Apart from offering a comprehensive textbook for undergraduate and postgraduate students in food, medical, and veterinary microbiology, this volume constitutes a valuable reference on foodborne diseases for medical professionals and health authorities, and forms an informative educational resource for the general public.
