“…In view of the fact that chicken meat which constitutes the maximum proportion of edible chicken contains less than this amount (0.873 mg) of chromium, it can be reasonably concluded that consumption of chicken containing only Cr(III) should not be of particular concern to public health. Similar conclusion can be drawn for chromium contamination in fish based on a recent study looking at chromium levels in fish and fish feed (Hasan et al 2016). A question may be raised as to whether Cr(III) will be oxidized to Cr(VI) while cooking.…”

“…Both investigations found slightly higher Cr concentrations than this study. Hasan et al [45] determined a Cr concentration of 0.75 ± 0.02 mg/kg (ww) in market fish from Dhaka, [46] determined a Cr concentration of 0.524 ± 0.053 mg/kg (ww) in cultured fish Pangasianodon hypothalamus in India, and [47] determined a Cr concentration of 0.54-2.46 mg/kg in cultured tilapia on Taiwan's southwest coast. Cr levels in all of these regions exceeded those found in our study.…”

Heavy metals (Pb, Cd, As, Mn, Fe, Zn, Cu, Ni, and Cr) are some of the most toxic elements that can bioaccumulate from sources linked to human activities, such as industry and agriculture. This study quantifies the concentrations of several heavy metals in caged tilapia found in Ghana’s Volta Basin and assesses the associated health risks. The levels of heavy metals in the tissues of Oreochromis niloticus from three cage farms (N = 52) were determined using Atomic Absorption Spectrometry (AAS). The implication for human health was assessed using several risk assessment techniques. Fe (50.11 ± 10.22 mg/kg) and Cr (0.31 ± 0.07 mg/kg) had the highest and lowest accumulated metal concentrations, respectively. Heavy metal concentrations in tilapia tissue from fish farms were ordered as follows: Fe > Mn > Zn > Ni > Cr (farm A), Fe > Zn > Ni > Mn (farm B), and Fe > Mn > Zn > Ni > Cr (farm C). All metals had an estimated daily intake (EDI) below the threshold, and mean differences between sample farms were not statistically significant. Similarly, the values of target hazard quotients (HQs) and hazard indices (HIs) were less than one. According to the risk assessment results, eating tilapia from farms posed no risk to human health. The presence of Mn, Fe, and Ni concentrations above the maximum level in the fish, on the other hand, suggests that they may affect fish health.
