We determined total mercury (Hg) distribution in muscle and liver of ten ray species and assessed health risk considering Hg levels in muscle and average consumption of rays in Mexico. Rays were collected from five sites in NW Mexico between March and November 2012. Hg concentrations ranged from 4.465 lg g1 in muscle of the longtail stingray Dasyatis longa to 0.036 lg g1 in liver of the diamond stingray Dasyatis dipterura. Considering all the individuals, Hg in muscle (1.612 ± 1.322 lg g1) was significantly (p < 0.05) higher than in liver (0.745 ± 0.616 lg g1). Regarding local health risk assessment, none of the ray species may cause adverse effects on consumers.
