The aim of this study was the screening for the presence of enteric human virus in shellfish (clam and cockle) collected from two production area in Moroccan Mediterranean coast. Between October 2006 and April 2008, forty four samples were collected and tested for viral contamination using cell culture (HEp-2 and Vero cells) and integrated cell culture PCR. Overall, 88.6 % of all analysed samples were contaminated by at least one of the studied viruses, Adenovirus was detected in 52.3 % of the samples and Enterovirus in 36.3%. The presence of viruses in shellfish production area can represent a potential health risk by causing gastroenteritis. The procedure used in this study may be a tool for monitoring shellfish viral contamination in Morocco.
