Six young Japanese black calves died within a few days demonstrating neurological signs such as tilted heads, ataxia, and collapse. Necropsy revealed cerebral edema, and rapid histological examination of one dead calf revealed cerebrocortical laminar necrosis, a characteristic sign of lead poisoning. Lead analysis of three calves revealed a higher concentration of lead in the blood than was found in unaffected calves. The source was discovered to be a piece of galvanized iron painted with paint containing lead. Its removal prevented additional occurrences of the illness.
