A simple method to recover Norovirus from fresh produce with large sample size by using histo-blood group antigen-conjugated to magnetic beads in a recirculating affinity magnetic separation system (RCAMS)

► A RCAMS system was developed to concentrate human norovirus from food samples. ► Kinetics study suggests 120 min is required for good recovery of the virus. ► Water wash followed by CBS adjustment resulted in an enhanced recovery of virus. ► RCAMS is a more sensitive, rapid and simple method than PEG method.
