Lead poisoning in cattle usually is the result of a single ingestion of a material containing a large quantity of lead. Poisoning in cattle also can result from the long-term ingestion of crops or pasture forage contaminated by lead settling out from fumes and dusts emitted from industrial lead operations. The latter is the principal source of poisoning for horses. Horses appear to be more susceptible than cattle to the long-term ingestion of lead. Whereas a daily intake of approximately 2 mg/kg can produce poisoning in horses, a daily intake of approximately 6-7 mk/kg is required to produce poisoning in cattle. Although the ingestion of small amounts of lead by food-producing animals may not result in clinical signs of lead poisoning, it should be emphasized that a small fraction of that ingested will be retained in the tissues and contribute to the dietary intake of man. 21 references.
