Technical Abstract: Molluscan shellfish may become contaminated with a wide variety of chemical and biological agents. Among those most commonly associated with illness are bacteria of the genus Vibrio and enteric viruses, including hepatitis A virus, the Noroviruses (Norwalk-like viruses), Sapporo-like viruses, and astroviruses. Practical methods are becoming available for the extraction and assay of shellfish-borne viruses, whereas, alternative processing techniques, like high hydrostatic pressure processing may be useful in inactivating not only Vibrios, but also viruses. Although the high pressures required to inactivate some viruses may compromise the quality of shellfish, other viruses appear to be inactivated by substantially lower pressures without negative effects on shellfish quality. Quantitative molecular assays for the enteric viruses have been recently developed and include the development of real-time reverse transcription-polymerase chain reaction and universal primer sets. Together, advances in virus detection technology and processing strategies should enhance the safety of molluscan shellfish.
