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

Development and spread of antimicrobial resistance is the result of an evolutionary process by which microorganisms adapt to antibiotics through several mechanisms including alteration of drug target by mutation and horizontal transfer of resistance genes. The concomitant occurrence of independent antimicrobial resistance mechanisms is a serious threat to human health and has appeared in several emerging epidemic clones over the past decade in humans and also in animals. The increasing prevalence of antimicrobial drug resistance among animal and zoonotic foodborne pathogens is of particular concern for public health. In this Ebook, we gathered a collection of articles which deal with the most important aspects of the genetics of acquired antimicrobial resistance extending from medically-important resistance, emerging epidemic resistant clones, main mobile genetic elements spreading resistance, resistomes, dissemination between animals and humans, to the “One Health” concept.

Microbiology is one of the core subjects for veterinary students,and since its first publication in 2002, Veterinary Microbiologyand Microbial Disease has become an essential text for students ofveterinary medicine. Fully revised and expanded, this new editionupdates the subject for pre-clinical and clinical veterinarystudents in a comprehensive manner. Individual sections deal withbacteriology, mycology and virology. Written by an academic teamwith many years of teaching experience, the book provides concisedescriptions of groups of microorganisms and the diseases whichthey cause. Microbial pathogens are discussed in separate chapterswhich provide information on the more important features of eachmicroorganism and its role in the pathogenesis of diseases ofanimals. The international and public health significance of thesepathogens are reviewed comprehensively. The final section isconcerned with the host and is organized according to the bodysystem affected. Tables, boxes and flow diagrams provide information in an easilyassimilated format. This edition contains new chapters on moleculardiagnostics and on infectious conditions of the skin,cardiovascular system, urinary tract and musculoskeletal system.Many new colour diagrams are incorporated into this edition andeach chapter has been updated.

Since the central theme of this book is the transmission of disease agents through the food chain, we will examine influenza viruses from this perspective. Influenza A viruses are found in humans, pigs, horses, sea mammals, and also in wild aquatic and domestic birds [23]. How are they spread? Between mammals, influenza is an airborne infection, but between birds, influenza can be either an airborne or waterborne infection. Influenza viruses of aquatic birds periodically transmit to domestic birds sometimes with catastrophic effects; this transmis sion can be either airborne or waterborne. Less frequently, avian influenza viruses transmit to mammals and three to four times in the past century this transmission has initiated a pandemic of influenza in humans. The method of spread of avian influenza viruses to mammals remains unresolved, but could be either airborne or waterborne. In this report we will consider recent examples of interspecies transmission of influenza A viruses and the possible prevention of emergence of the next human pandemic which is considered imminent. The reservoirs of influenza A viruses The available evidence indicates that aquatic birds are the reservoirs of all 15 subtypes of influenza A viruses. We will first consider the replication of influenza A in aquatic birds. In wild ducks, influenza viruses replicate preferentially in the cells lining the intestinal tract, cause no disease signs, and 8 7 are excreted in high concentrations in the feces (up to 10 .

The polymerase chain reaction has become an increasingly important tool in microbial diagnosis in recent years, mainly because of its rapidity, high sensitivity, and specificity. This book provides microbiologists and biochemists state-of-the-art protocols for the use of PCR-based identification and detection of important bacterial and other microbial pathogens. The chapters have been contributed by leading investigators well-conversant with PCR, who also offer practical expertise to the important area of pre-amplification processing. All micrbiologists, biochemists, and microbial researchers will find this to be a valuable reference for their PCR diagnosis of microbial pathogens.
