Abstract
The aim of this paper is to evaluate the food safety of the red king crab from Norwegian waters and obtain information on possible geographical and gender differences. Samples of claw and leg meat of 185 red king crabs (Paralithodes camtschaticus), collected from 23 positions in the Barents Sea, were analysed for dioxins, furans, non-ortho and mono-ortho PCBs, non dioxin-like PCBs, polybrominated diphenyl ethers, and perfluorinated alkyl substances and elements, such as arsenic, cadmium, mercury and lead. The concentrations of persistent organic pollutants and metals were low compared to maximum levels laid down in European regulations. Hence, red king crab is a safe food. Significant differences in the concentrations of metals among different areas, and between male and female crabs, were found. Positive correlations were found between carapace length and mercury, methylmercury and cadmium concentrations, and between fat and arsenic and inorganic arsenic concentrations.
