##'''''Lead'''''-Lead can occur in animals grazing near smelting plants or from animals licking lead based paints or old car batteries. Lead then accumulates in the bones. Acute poisoning may result in high levels in the liver & kidneys. Chronic exposure may cause softening & cavitation of the CNS.

##'''''Arsenic'''''
##'''''Arsenic'''''-Contamination of food animals with arsenic is typically due to exposure to arsenical herbicides, rodenticides or insecticides. Its accumulation in the liver & kidneys can lead to fatty degeneration. It also accumulates in the bones.
##'''''Mercury'''''-Rare cases of mercury poisoning have been due to animals being fed with grain treated with mercury-based anti-fungicides. The result is enlarged internal organs & petechiation). Inorganic mercury is also stored in the liver & kidneys, whereas organic mercury is more widely distributed. See [http://www.env.go.jp/en/chemi/hs/minamata2002/|Minamata disease]
