Improving Food Safety Through a One Health Approach


Book Description

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.




Transmission of Antimicrobial Resistance from Livestock Agriculture to Humans and from Humans to Animals


Book Description

Abstract: The emergence of a resistant pathogen reduces the effectiveness of antibiotics in preventing or treating an infection caused by a micro-organism, thus increasing morbidity and mortality and leading to higher economic costs to livestock producers. An understanding of the underlying disease dynamics is crucial in finding appropriate solutions to containing the rise in antimicrobial resistance. This report synthesises the evidence on the potential modes of transmission of antimicrobial resistance between humans and animals and vice versa. In particular, the important role of the environment in the transmission chain is discussed as well as practices to break this link. This report also illustrates some of the commonly shared antibiotic classes that are used in human medicine and animal production, and the overall trends in the usage of these antibiotics. While information on transmission of resistance is sparse, the report highlights several priority areas where future research could focus in order to bring a greater understanding of these interactions




WHO guidelines on use of medically important antimicrobials in food-producing animals


Book Description

WHO has launched new guidelines on use of medically important antimicrobials in food-producing animals, recommending that farmers and the food industry stop using antibiotics routinely to promote growth and prevent disease in healthy animals. These guidelines aim to help preserve the effectiveness of antibiotics that are important for human medicine by reducing their use in animals.




The Use of Drugs in Food Animals


Book Description

The use of drugs in food animal production has resulted in benefits throughout the food industry; however, their use has also raised public health safety concerns. The Use of Drugs in Food Animals provides an overview of why and how drugs are used in the major food-producing animal industriesâ€"poultry, dairy, beef, swine, and aquaculture. The volume discusses the prevalence of human pathogens in foods of animal origin. It also addresses the transfer of resistance in animal microbes to human pathogens and the resulting risk of human disease. The committee offers analysis and insight into these areas: Monitoring of drug residues. The book provides a brief overview of how the FDA and USDA monitor drug residues in foods of animal origin and describes quality assurance programs initiated by the poultry, dairy, beef, and swine industries. Antibiotic resistance. The committee reports what is known about this controversial problem and its potential effect on human health. The volume also looks at how drug use may be minimized with new approaches in genetics, nutrition, and animal management.







Antimicrobial Resistance in Bacteria from Livestock and Companion Animals


Book Description

The global spread of antimicrobial-resistant pathogenic bacteria is a continuing challenge to the health care of humans and domesticated animals. With no new agents on the horizon, it is imperative to use antimicrobial agents wisely to preserve their future efficacy. Led by Editors Stefan Schwarz, Lina Maria Cavaco, and Jianzhong Shen with Frank Møller Aarestrup, an international team of experts in antimicrobial resistance of livestock and companion animals has created this valuable reference for veterinary students and practitioners as well as researchers and decision makers interested in understanding and preventing antimicrobial resistance.

Researchers, scientists and practitioners will find this an essential resource on the judicial use of antibiotics in animals and humans. Explores all the genera of livestock and fish originated pathogenic bacteria associated with antimicrobial resistance Presents cutting-edge research on epigenetics, nanotechnology and intervention technologies Discusses transmission dynamics of resistance gene pools from different reservoirs, including food animals, poultry, fishes and the environment




Animal nutrition strategies and options to reduce the use of antimicrobials in animal production


Book Description

Antimicrobial resistance is a global and increasing threat. Stewardship campaigns have been established, and policies implemented, to safeguard the appropriate use of antimicrobials in humans, animals, and plants. Restrictions on their use in animal production are on the agenda worldwide. Producers are investing in measures, involving biosecurity, genetics, health care, farm management, animal welfare, and nutrition, to prevent diseases and minimize the use of antimicrobials. Functional animal nutrition to promote animal health is one of the tools available to decrease the need for antimicrobials in animal production. Nutrition affects the critical functions required for host defence and disease resistance. Animal nutrition strategies should therefore aim to support these host defence systems and reduce the risk of the presence in feed and water of potentially harmful substances, such as mycotoxins, anti-nutritional factors and pathogenic bacteria and other microbes. General dietary measures to promote gastrointestinal tract health include the selective use of a combination of feed additives and feed ingredients to stabilize the intestinal microbiota and support mucosal barrier function. This knowledge, used to establish best practices in animal nutrition, could allow the adoption of strategies to reduce the need for antimicrobials and contain antimicrobial resistance.




Ethics and Drug Resistance: Collective Responsibility for Global Public Health


Book Description

This Open Access volume provides in-depth analysis of the wide range of ethical issues associated with drug-resistant infectious diseases. Antimicrobial resistance (AMR) is widely recognized to be one of the greatest threats to global public health in coming decades; and it has thus become a major topic of discussion among leading bioethicists and scholars from related disciplines including economics, epidemiology, law, and political theory. Topics covered in this volume include responsible use of antimicrobials; control of multi-resistant hospital-acquired infections; privacy and data collection; antibiotic use in childhood and at the end of life; agricultural and veterinary sources of resistance; resistant HIV, tuberculosis, and malaria; mandatory treatment; and trade-offs between current and future generations. As the first book focused on ethical issues associated with drug resistance, it makes a timely contribution to debates regarding practice and policy that are of crucial importance to global public health in the 21st century.
