a form of poisoning caused by the presence of lead or lead salts in the body. Lead poisoning affects the brain, nervous system, blood and digestive system. It can be either chronic or acute. This is a common finding in cattle and in urban dogs because of the frequent presence of lead in the environment in lead paints, and the sweet taste of the paint when it is weathered.
Adult animals show a subacute syndrome of severe depression, aimless walking, blindness, complete ruminal stasis and a black diarrhea in small amounts. Calves show violent convulsions and death within a few hours.
Poisoning can result from swallowing paint flakes or chewing surfaces covered with lead-based paints, golf balls, newsprint, linoleum, fishing sinkers, or numerous other household objects containing lead. Clinical signs usually include abdominal pain, vomiting, diarrhea and seizures. Basophilic stippling of red blood cells, nucleated red blood cells, and a moderate anemia are characteristic.
