Advances in diagnostic techniques and their widespread use for infectious agents revealed the considerably high current prevalence of viral agents in foodborne and waterborne diseases. Foodborne and waterborne viruses are indicated to cause not only gastroenteritis and hepatitis but also neurological disorders, respiratory tract diseases, myocarditis, glomerulonephritis and hemorrhagic fever, with a particularly high mortality rate in infants/children and in individuals with immune deficiency. Additionally, due to their resistance to environmental conditions and food processes compared to other microorganisms, elimination of these viruses by heat and high pressure applications, natural antiviral compounds, UV applications and conventional cleaning-disinfection remains difficult even inadequate. In protection from viral infections, vaccine applications together with GMP, GHP and HACCP system approaches in production seem to be the most effective approaches to ensure the minimization of viruses in food environment and in public. In this review article, up-to-date information is presented on the general characteristics and the diseases caused by enterotropic viruses; NoV, AstV, RoV, AdV and hepatotropic viruses; HAV and HEV, with a particularly high worldwide prevalence, as well as their epidemiology, prevention and their control measures.
