This book addresses the gaps in our knowledge of foodborne viruses, and the implication of these gaps. It explains what lessons we can learn from the past about early detection and control of (emerging) viral infections. It looks at the role of viral changes through mutation and recombination on their biological properties and epidemiology. It features chapters written by leading scientists in the field, who have been encouraged to provide a challenging in depth discussion and share their vision for future directions. It intends to provide a basis to help scientists and risk managers as they decide on the best options for controlling food-borne disease.
