L’évaluation du risque dans les produits aquacoles: le loup d’elevage (Dicentrarchus labrax) (Linneaus, 1758),Actes

Abstract

The European food regulation is based on three concepts concerning food safety: risk assessment, management and

communication. The risk assessment is considered as the scientific component of the risk analysis.The aim of this study is to make a

risk evaluation about heavy metals (Cd, Pb, Hg) in farmed sea bass.The assessment of exposure to heavy metals was carried out

using the EWI (Estimated weekly intake) method, that is a value that relates the maximum weekly intake in the diet and heavy metal

contamination in the food. Our goal is to define the concentration of Pb, Cd, Hg derived from consumption of farmed sea-bass (EWI)

to the PTWI, to check what effects has the percentage the PTWI heavy metals considered. The results showed that for all metals, the

EWI values are lower than those of the PTWI; in fact they represent 5.3% of cadmium of PTWI, 2.02% of lead of PTWI and

only 0.35% of mercury of PTWI. The obtained results, considering meta-analysis and consumption data, show that intake of heavy

metals from farmed sea bass consumption is minimal, and consequently these fish were safe for human consumption.
