#### **Abstract**

Human noroviruses (hNoVs) and hepatitis A virus (HAV) are the leading cause of food‐ borne viral illness, and they exact a considerable economic and health toll worldwide. The detection of viral contamination in foods requires highly sensitive and accurate methods, due to the intrinsically low amounts of viruses and the complexity of the sam‐ ple matrices. In recent years, a wide variety of nucleic acid-based molecular methods have been developed for the detection of hNoVs and HAV, displaying superior sensitivi‐ ty, specificity, and speed. This chapter aims to provide a summary of the application of the molecular methods for the detection of the two important foodborne viruses.
