The aim of the present manuscript was to determine the total Hg content in edible tissue of Crassostrea iridescens fed with three different diets (D1: Molasses/yogurt, D2: Sea water and D3: Microalgae: Isochrysis spp.) under laboratory conditions. After 114 days of experiment, the total Hg content in edible of oyster was similar (D1:1.07±0.780 µg/g, D2: 1.041±0.078 µg/g, D3: 0.964±0.214 µg/g d.w.). This tendency also was observed in each ingredient used for dietary treatments (Isochrysis spp.: 2.591±0.280 µg/g, Molasses: 2.320±0.174 µg/g, Yogurt: 2.707±0.22 µg/g). No significant differences were observed in Hg content in tissues and neither dietary ingredients (p>0.05). The consumption of oyster of this experiment do not represent a potential risk for human consumption, due to Hg values were below the limit established by Mexican Officially Norm 242.
