title: Inorganic arsenic toxicosis in a beef herd.
abstract: Over a 44-day period, 4 of 5 affected calves in a 170-head herd of beef cattle died after exhibiting clinical signs of lethargy, ataxia, anorexia, and diarrhea. Histopathological examination of tissues and toxicological analysis of a suspicious powder discovered in the pasture confirmed arsenic trioxide toxicosis.
