During the 5-year period from January 1, 1990, to December 31, 1995, 887 diagnoses of metal toxicosis in domestic animals and wild birds were documented at the Veterinary Laboratory Services Branch of the Ontario Ministry of Agriculture, Food and Rural Affairs. Most of these cases involved cattle, sheep, and birds. Lead toxicosis was diagnosed in 399 cases, copper toxicosis in 387, zinc toxicosis in 49, mercury toxicosis in 44, iron toxicosis in 4, and selenium in 4 cases. Trends in species affected and sources of metals are discussed.
