Description
Summary:Global seafood consumers are increasingly concerned about and prefer safe, high-quality, and hazard-free seafood products. This study investigated various Pakistani processing plants supplying the international market and explored commercially important seafood species (fish, crustaceans, and cephalopods) for metal content, contamination, and potential health risks. The results showed that the metal concentrations differed significantly among species. The metals loads were as Fe > Cu > Zn > Mn > Pb > Ni > Cd > Hg. Contamination factor (CF), pollution load index (PLI), and metal pollution index (MPI), verified negligible contamination of seafood. As assessed by the estimated daily intake, target hazard quotient, hazard index, and carcinogenic risk, the potential human health risks associated with the contaminated seafood were lower than the perceived threat. In conclusion, seafood processing plants export products that meet international food safety standards and are safe for consumers worldwide. •We investigated the metal loads and human health risks in seafood items.•Metals loads showed an array of Fe > Cu > Zn > Mn > Pb > Ni > Cd > Hg.•Metals burden below national and international permissible limits.•CF, PLI, and MPI estimated a negligible health risk to consumers.•Pakistani seafood items meet global food safety standards.
