If that were the case, the higher incidence of F-RNA coliphage GII and GIII
in federally registered plants may be attributed to the increased
handling that occurs in the large processing plants, where beef
cuts are handled by a large number of people working at different
stations along conveyer belts while in the smaller provincially
registered plants the cuts are handled by only a few employees.
The concern of transmission of human viruses via meat was also
raised by Mattison et al. (2007), who detected RNA associated
with the human norovirus GII.4 cluster in 1/156 retail meat
samples.
