EFFICIENCY OF VIRAL CONCENTRATION IN FOOD SAMPLES: COMPARISON BETWEEN PEG AND ULTRAFILTRATION TECHNIQUES

Norovirus is the most prevalent causative agent of foodborne diseases. However, the detection of this virus in foods other than shellfish is often time-consuming and unsuccessful. The objective of this study is to compare PEG and ultrafiltration techniques for viral concentration in bivalve molluscs. An experiment with Coxsackie B5 and feline Calicivirus strain F is conduct to determine the efficiency of each virus concentration. Ultrafiltration technique is the most indicated.
