Lead poisoning was diagnosed in 63 herds of Iowa cattle during a 5-year period. Diagnosis was based upon clinical signs, postmortem studies, history of exposure, and blood and tissue chemistry. Morbidity and fatality rates were compiled, and determination of a source of intoxication was attempted in all cases. The majority of cases were found due to ingestion of paint, used motor oil, grease, and batteries. A probable source of lead was found in 76% of the cases investigated. Most instances were associated with suboptimal management, allowing exposure to lead sources. Clinical signs were characteristic including various central nervous system derangements, blindness, and gastrointestinal dysfunction. The relative frequency of specific clinical signs was determined. A definite increase in seasonal incidence was found, with 70% of cases occurring in the first 6 months of the calendar year. Chemical analysis for lead was done by Atomic Absorption Spectroscopy and was correlated with clinical diagnoses in each case.
