Abstract
Real-time reverse transcription PCR revealed that new St-Valerien–like porcine caliciviruses are prevalent (2.6%–80%; 23.8% overall) in finisher pigs in North Carolina. One strain, NC-WGP93C, shares 89.3%–89.7% genomic nucleotide identity with Canadian strains. Whether these viruses cause disease in pigs or humans or are of food safety concern requires further investigation.

Viruses in the family Caliciviridae are nonenveloped, polyadenylated, single-stranded, positive-sense RNA viruses (1). They have been classified into 5 genera (Norovirus, Sapovirus, Vesivirus, Lagovirus, and Nebovirus) since 2009 (www.ictvonline.org). Later, the nonhuman primate Tulane virus (2) and the porcine St-Valerien–like viruses (3) were characterized as potential new genera in the Caliciviridae family.
