This is the first book to focus entirely on viruses in foods. It collates information on the occurrence, detection, transmission, and epidemiology of viruses in various foods. Although methods for bacterial detection in food are available, methods for detection of viruses in food, with the exception of shellfish, are not available. It is important, therefore, to develop methods for direct examination of food for viruses and to explore alternate indicators that can accurately reflect the virological quality of food. This book addresses these issues along with strategies for the prevention and control of viral contamination of food.

Viruses can be highly infectious and are capable of causing widespread disease outbreaks. The significance of viral pathogens in food and waterborne illness is increasingly being recognised and viruses transferred by these routes are important areas of research. Viruses in food and water reviews the risks, surveillance and control of food and waterborne viral disease. Part one provides an introduction to food and environmental virology. Part two goes on to explore methods of detection, surveillance and risk assessment of viruses in food and water; it includes chapters on molecular detection of viruses in foods and food processing environments, quality control in the analytical laboratory, and quantitative risk assessment for food and waterborne viruses. Part three focuses on virus transmission routes and control of food and water contamination. It contains chapters on fresh produce, shellfish and viral presence, and control methods in waste water and sewage. Finally, part four highlights particular pathogens including norovirus, hepatitis A and emerging zoonotic viruses. Viruses in food and water is a standard reference book for microbiologists in academia, analytical labs and the food and water treatment industries, as well as environmental health professionals and researchers working on foodborne viruses. Explores methods of detection, surveilance and risk assessment of viruses in food and water Considers virus transmission routes and control of food and water contamination Highlights advances in the understanding of specific pathogens, including norovirus, hepatitis A and rotaviruses and the advances in vaccine development

Food-borne viruses are recognized as a major health concern, but their distribution, definition, and impact are poorly understood. The volume Food-Borne Viruses goes a long way in correcting that problem. Written by leading scientists in the field, it brings together the latest knowledge on these viral strains, their detection and control, and associated challenges.

The Human Noroviruses (NoVs) and hepatitis A virus (HAV) are currently recognized as the two most epidemiologically important foodborne virus pathogens. They are both highly infectious and can lead to widespread outbreaks. Complicating factors that enhance their wide and easy spread include the fact that theoretically any product could be contaminated with these viral agents, their infectious dose is usually low, and they demonstrate considerable resistance to a number of inactivation agents and processes. Their detection in food, clinical, and environmental samples usually rely on molecular-based methods, as there are no susceptible cell lines yet available that support the proliferation of neither the wild-type HAV, nor the NoVs. The most crucial, and difficult step in virus detection is the extraction of virus particles from the food matrix, as it is of great necessity that during the isolation all the matrix-associated inhibitors are removed. In an effort to address these concerns, four individual studies were designed and conducted. We first considered the PathatrixÔ system as an alternative sample processing technique to concentrate HAV from representative foods. The virus capture is believed to happen when the negatively charged proteins in the virus capisd bind to the positively charged magnetic particles used in the PathatrixÔ scheme. We were able to use this machine and consistently concentrate HAV from a variety of at-risk food items including lettuce, green onions, strawberries, deli turkey, oysters, and cake. We further amplified the virus RNA with RT-PCR and confirmed HAV detection with dot-blot hybridization. We were able to detected HAV in all food items at a seeding level of 100PFU per 25g sample, which is consistent with the virus load to be anticipated in naturally contaminated products. We were also able to develop a rapid and quantitative approach to detect HAV in food matrices; when we used a Real-time RT-PCR protocol that includ.

This report draws attention to the threat of viruses as a risk to public health when they are present in food. Viruses play a major role in the burden of infectious intestinal disease and require special and separate attention because they behave differently from bacteria. In identifying the major routes of viral contamination of foods, this report seeks to highlight those areas which need immediate attention and provide guidance to both risk assessors and risk managers in understanding the challenges to be overcome in effectively addressing the problems associated with foodborne viruses. This volume and other in this series, co-published with WHO, contain information that is useful to both risk assessors and risk managers, the Codex Alimentarius Commission, governments and food regulatory agencies, industry and other people or institutions with an interest in foodborne viruses, their public health impact and approaches for the evaluation and selection of potential control strategies.
