Foodborne diseases are one of the most serious concerns in public health. It is estimated that around 600 million cases of gastroenteritis occur worldwide each year. At present, more than 200 food-borne diseases are known, which can cause from mild gastroenteritis to syndromes with a fatal outcome, with the added possibility of chronic complications. One of the major etiological agents in foodborne diseases are the food and waterborne viruses, which are attracting a great deal of attention to researchers, food hygienists and policy makers. Several aspects differentiate these pathogens from foodborne pathogenic bacteria: their high capacity for infection and preservation in food environments, and their difficulty for a correct and sensitive detection. In recent years, different initiatives have been carried out to prioritize research in the area of viruses in food, prioritizing different aspects of their detection, epidemiology and control. There is clear evidence that the existing data on their prevalence may be underestimated due to the lack of robust methods for their sensitive detection. It is also necessary to know exactly what the incidence is in the different stages of the food production chain, and particularly in that which is dedicated to the transformation of products of animal origin. Finally, it is also necessary to calibrate the current disinfection procedures in the food industry in order to reliably establish a quantitative evaluation of the viral risk in food.
