Arsenic toxicosis occurred in cattle from 2 herds located along rivers in western South Dakota that have been contaminated by effluence of mine tailings during many years of gold mining in the area. Clinical signs in cattle of various ages from herd A included aberrant behavior, progressive weakness, abscess formation, emaciation, and agonal convulsions. Cows from herd B exhibited posterior ataxia and recurrent epileptiform convulsions. Hepatic lipidosis was found in 2 cows, and cerebral edema plus necrosis of cerebrocortical neurons was seen in the brain of 1 cow. Soil from the cattle yard of premise A, which is on the floodplain of a contaminated creek, contained 2200 ppM arsenic. Corn silage that has been contaminated with soil during silo-filling contained 140 ppM arsenic. The arsenic content of hair from herd A cattle ranged from 2.4 to 22.0 ppM and the arsenic content of the liver and kidney of 1 cow from herd B was 3.0 and 7.0 ppM, respectively.
