| Resumo: |
Shellfish consumption is clearly associated with the transmission of enteric viruses. The channel of transmission of enteric viruses to human beings could be decreased particularly if the systems of depuration of shellfish were optimized, standardized and if their viral efficiency was controlled. The purpose of this work was to study the contamination of oysters and to assess the efficiency of several depuration processes. Our study have demonstrated that in some cases, 50% of oysters samples contain enteric viruses or H.A.V. antigen and the quantities of viruses range from 17 to 246 FF for the rotaviruses and from 124 to 200 for the enteroviruses per 100 g of tissue. According to our results, the exclusive use of a bacteriological criterium to determine the sanitary quality of oysters is insufficient. Regarding the methodologies of the depuration of oysters, it appears that maintaining naturally contaminated oysters in degorging tanks for 3 days gives satisfying bacteriological results but does not yield in every cases to the disappearance of the hepatitis A antigen.
