Abstract:
As frequent occurrences of the foodborne disease outbreak,food safety has become a severe health problem worldwide.Studies have shown that the viruses are the most common cause for the foodborne diseases.Foodborne viruses can exist on the surface or inside of foodstuffs,cause outbreak and epidemic of the diseases,which are seriously harmful to human health and even bring about inestimable economic losses to the food enterprises.In order to identify the presence of foodborne viruses in food products in a timely manner,sensitive methods are therefore needed.In general,the strategy for detection of foodborne viruses in food products requires 3 steps:virus extraction,purification of the viral genomic material (RNA for the majority of food-borne viruses),and molecular detection.However,in practice,it is more difficult to detect foodborne viruses in foodstuffs,because the amount of viruses in foodstuffs is low and the composition of food matrix is complex.In this review on published literatures,we summarized currently available methods for the detection of viruses in different food matrices to provide references for further studies on foodborne virus detection.
