“…Moreover, hippopotami liver contained higher levels of Zn and Cu compared to those of soil, sediment and plants (Tables 1 and 4). Similar to our results, high concentrations of Zn and Cu were observed in wild reindeer and cattle liver (Nriagu et al, 2009;Lopez-Alonso et al, 2002;Miranda et al, 2005;Sivertsen et al, 1995). Since Zn and Cu are essential elements in animals and play important roles in many physiological functions such as catalytic centers of liver Cu/Zn superoxide dismutase (Cu/Zn-SOD) (Zelco et al, 2002), we suggested that a wider range of Cu and Zn concentrations can be accumulated in hippopotami liver compared to non-essential elements.…”

Hippopotami (Hippopotamus amphibius L) are large semi-aquatic mammals that can be exposed to metals and metalloid from both terrestrial and aquatic environments.Therefore, knowledge of metal and metalloid accumulation characteristics in hippopotami living in the national park is important from ecotoxicological point of view. Cd levels than those of soil. These results strongly suggest that hippopotami liver accumulate higher levels of these metals if surrounding environment is contaminated.Levels of Cr and Ni in hippopotami liver were higher compared to other toxic metals.Since this is the first report to show the Cr and Ni levels and bio-accumulation characteristics of Hg and Cd in hippopotami, we concluded that continuous monitoring and evaluation of toxic effects of these metals on hippopotami should be conducted.

“…The levels of Pb and Cd in the present study were lower than those previously reported by Yabe et al [15] in cattle offal from Kabwe, a Pb-Zn mining town in the central province of Zambia. Studies in cattle from polluted environments in other countries have reported Pb and Cd accumulations exceeding the benchmark values in offal [10,11,13]. Although toxic metal concentrations in the current study were low and did not pose immediate health risks, the levels of Pb and Cd indicate potential for increased accumulation, if exposure is prolonged as these metals bioaccumulate and bioconcentrate in organs and tissues of animals [14].…”

ABSTRACT. Intensive agricultural practices are recognized as significant sources of metal pollution in soils and pasture. This study investigated metal contamination in cattle offal from an agricultural area in Zambia, where inorganic fertilizers, agricultural lime, and pesticides are routinely applied. The highest median values (mg/kg, wet weight) of Cu (40.9), Zn (35.2), Cr (1.35) and Ni (0.594) were recorded in the liver, whereas the highest median values of Pb (0.061) and Cd (0.049) were found in kidneys. Maximum levels of Hg, As and Co were under 0.2 mg/kg in both organs. Pb and Cd did not exceed the benchmark values in cattle offal for human consumption and did not pose immediate health risks. Concentrations of Ni and Cr could present a public health concern. Monitoring of metal accumulations in offal of cattle, not only from well-known polluted environments but also agricultural areas, should be done regularly for the health of human consumers. KEY WORDS: cattle, kidney, liver, metal accumulation, Zambia.doi: 10.1292/jvms.12-0142; J. Vet. Med. Sci. 74(10): 1345-1347, 2012 The accumulation of toxic metals in food animals is recognized as a public health hazard worldwide. Toxic metals can be lethal and tend to accumulate in the liver, kidneys, bones, and other tissues [8]. Metals including Pb, Cd, Hg, and As are readily transferred through food chains and pose potential health risks to human consumers. Sources of metal contamination in livestock production systems can be natural and anthropogenic. In agricultural systems that integrate livestock and crop production, intensive agricultural practices are recognized as significant sources of metal accumulation [9]. Fertilizers and agricultural lime contain metal impurities, and it is widely reported that application of these agrochemicals, especially phosphate fertilizers, results in accumulation of metals in agricultural soils [9,12]. Metallo-pesticides, including insecticides, fungicides, and herbicides, are also known to contain various metals that can increase metal accumulation [12]. Thus, the present study determined Pb, Cd, Hg, As, Ni, Cr, Cu, Zn, and Co concentrations in the liver and kidneys of cattle from an agricultural area in Zambia to provide a preliminary assessment of metal accumulation in cattle offal, and the potential risks to human consumers as cattle liver and kidneys are widely consumed in Zambia.Paired liver and kidney samples were collected in October, 2009 from 112 mixed breed male and female adult cattle slaughtered at abattoirs in Lusaka (latitude 15° 25' S, longitude 28° 16' E), the capital city of Zambia. Cattle slaughtered at these abattoirs came from commercial farms in the Chisamba agricultural block, located approximately 50 km north of Lusaka City. Samples were transported to the Graduate School of Veterinary Medicine, Hokkaido University, Japan for metal concentration analysis.Metals (except for Hg) were extracted from the liver and kidney samples by acid digestion using the method of Nakayama [7] with minor modifications.

“…Jamaica, where soil Cd concentrations are high, cattle kidney Cd concentrations between 0.012 and 117 mg/kg have been reported (Nriagu et al, 2009). From an animal health perspective, kidney Cd concentrations between 0.05-1.5 ppm wet weight are described as normal, 5.0-36 ppm wet weight as high and 100-250 ppm as toxic chronic (Puls, 1994).…”

“…The poor efficiency of cellular export systems explains the long residence time of Cd the kidneys (EFSA, 2009), resulting in older animals having higher kidney Cd concentrations (Nriagu et al, 2009) Alonso et al, 2004).

“…It is believed that a better understanding of the interaction of Cd with other elements may provide the key to understanding the effects of Cd on health. Cadmium is not easily cleared by the cells and the poor efficiency of cellular export systems explains the long residence time of this element in storage tissues such as the intestine, the liver and the kidneys (EFSA, 2009), resulting in older animals having higher liver and kidney Cd concentrations (Nriagu et al, 2009) even if the concentrations in their diets and water are consistently low (NRC, 2005). Perturbation of calcium (Ca), zinc (Zn) or iron (Fe) homeostasis plays a key role in Cd toxicological action that involves a general threat to basic cellular functions.…”

Of all animal tissues, livers and kidney constitute a special dilemma in that they have a tendency to bioaccumulate toxic metals such as arsenic (As), cadmium (Cd), lead (Pb) and mercury (Hg). Maximum concentrations (ML) for Hg, Pb, Cd and tin (Sn), but not As in foodstuffs are set by European Commission Regulations. The aims of this study were 1) to determine the concentrations of As, Cd, Pb and Hg in the livers and kidneys of nine cows from the index farm and 2) to combine the kidney Cd results from these 5 cows with those reported in an earlier Department of Agriculture Fisheries and Food (DAFF) report (n = 14 animals), and describe the trend in kidney Cd concentrations on the index farm over time.
