The drastic increase of human population and industrial wastes mostly affects coastal areas. Crabs with limited mobility, especially in benthic regions of the coasts, are more affected by metal pollution. Monitoring of trace metals in terms of food safety and potential health risks is important for consumers. Warty crab (Eriphia verrucosa) samples were collected with trammel nets between July 2015 and June 2016. The crab extracts were analyzed by an ICP-MS optical emission spectrophotometer. Trace metal densities of crab meats in the present study were determined in the order of Zn > Cu > Fe > As > Al > Mn > Hg > Pb ≥ Cd. These levels were below the acceptable values reported by the Turkish Food Codex and the EU Commission. The target hazard quotient (THQ) was above 1 in terms of As, Cu, and Hg trace metals in both groups. This study showed that although the level of trace metal was below allowable values, consumption of warty crab more than once a month may cause metal toxicity according to potential health risk analyses.
