Analytical Methods for Virus Detection in Water and Food ArchiMer
Bosch, Albert; Sanchez, Gloria; Abbaszadegan, Morteza; Carducci, Annalaura; Guix, Susana; Le Guyader, Soizick; Netshikweta, Rembuluwani; Pinto, Rosa M.; Van Der Poel, Wim H. M.; Rutjes, Saskia; Sano, Daisuke; Taylor, Maureen B.; Van Zyl, Walda B.; Rodriguez-lazaro, David; Kovac, Katarina; Sellwood, Jane.
Potential ways to address the issues that relate to the techniques for analyzing food and environmental samples for the presence of enteric viruses are discussed. It is not the authors' remit to produce or recommend standard or reference methods but to address specific issues in the analytical procedures. Foods of primary importance are bivalve molluscs, particularly, oysters, clams, and mussels; salad crops such as lettuce, green onions and other greens; and soft fruits such as raspberries and strawberries. All types of water, not only drinking water but also recreational water (fresh, marine, and swimming pool), river water (irrigation water), raw and treated sewage are potential vehicles for virus transmission. Well over 100 different enteric viruses...

Detection and Quantification of Noroviruses in Shellfish ArchiMer
Le Guyader, Soizick; Parnaudeau, Sylvain; Schaeffer, Julien; Bosch, Albert; Loisy, Fabienne; Pommepuy, Monique; Atmar, Robert L..
Noroviruses (NoVs) are the most common viral agents of acute gastroenteritis in humans, and high concentrations of NoVs are discharged into the environment. As these viruses are very resistant to inactivation, the sanitary consequences are contamination of food, including molluscan shellfish. There are four major problems with NoV detection in shellfish samples: low levels of virus contamination, the difficulty of efficient virus extraction, the presence of interfering substances that inhibit molecular detection, and NoV genetic variability. The aims of this study were to adapt a kit for use with a method previously shown to be efficient for detection of NoV in shellfish and to use a one step real-time reverse transcription-PCR method with addition of an...

Foodborne viruses: Detection, risk assessment, and control options in food processing ArchiMer
Bosch, Albert; Gkogka, Elissavet; Le Guyader, Soizick; Loisy-hamon, Fabienne; Lee, Alvin; Van Lieshout, Lilou; Marthi, Balkumar; Myrmel, Mette; Sansom, Annette; Schultz, Anna Charlotte; Winkler, Anett; Zuber, Sophie; Phister, Trevor.
In a recent report by risk assessment experts on the identification of food safety priorities using the Delphi technique, foodborne viruses were recognized among the top rated food safety priorities and have become a greater concern to the food industry over the past few years. Food safety experts agreed that control measures for viruses throughout the food chain are required. However, much still needs to be understood with regard to the effectiveness of these controls and how to properly validate their performance, whether it is personal hygiene of food handlers or the effects of processing of at risk foods or the interpretation and action required on positive virus test result. This manuscript provides a description of foodborne viruses and their...

Rotavirus VLP2/6: a new tool for tracking rotavirus in the marine environment ArchiMer
Loisy, Fabienne; Atmar, Robert L.; Cohen, Jean; Bosch, Albert; Le Guyader, Soizick.
The potential of rotavirus 2/6-virus-like-particles (VLP2/6) for use as tracers in the marine environment was investigated. The stability of bovine rotavirus (strain RF) and VLP2/6 in natural seawater at 25degreesC for six days was studied. ELISA and western blot methods were used to quantify the particles. The rates of decline of rotavirus particles and VLP2/6 were similar (approximately 0.5 log 10 per day). Western blot analysis showed that the integrity of capsid proteins VP2 and VP6 was conserved during the incubation time. These results demonstrate that VLP2/6 particles have the same stability in seawater as rotavirus particles. Thus, VLP2/6 can be used as a tracer, which should be of particular value for studying the fate of rotavirus particles in...
