Evaluation of viral concentration methods from irrigation and processing water

► We compared four viral concentration methods for their recovery in water. ► MNV-1 and MS2 phages were used as surrogate viruses during this study. ► All methods were evaluated in processing water and four types of irrigation water. ► The best method used a negatively charged membrane with the Tr alk elution buffer. ► The best method was tested for its recovery of HAV, GI and GII NoV and RV.
