- This research project aims to adapt existing methods to establish a simple, reliable, robust and well standardised method for Norovirus detection.
The overall objective of this project is to develop and establish PCR methods for the detection of human enteric viral pathogens (Norovirus and hepatitis A virus) contaminating molluscan shellfish that are as simple as possible and that are reliable, robust and well standardised.
Achievement of this objective would enable a wider uptake of such test methods by more routine food control laboratories.

- Filter-feeding bivalve molluscan shellfish (oysters, mussels, etc) concentrate microbial contaminants occurring in their growing waters and may present a health hazard when consumed raw or lightly cooked.
Human enteric viruses, occurring as a consequence of sewage contamination of growing waters, are the pathogens most frequently associated with illness following shellfish consumption.
Control measures for such contamination are hindered by the current absence of routine test methods for detection of such viruses in shellfish.
The successful detection of enteric viral pathogens such as Norovirus (NV) and hepatitis A in molluscan shellfish relies on Polymerase Chain Reaction (PCR) based techniques.
The presence of NVs can be readily demonstrated in shellfish from polluted harvesting areas, but detection in less polluted shellfish products is more difficult due to lower levels of virus being present.
