Abstract
Lead poisoning in livestock, particularly cattle, is a significant yet preventable animal welfare and food safety concern frequently caused by the ingestion of discarded lead-acid batteries. Degraded by weathering, these batteries expose toxic lead plates and sludge that are often palatable to curious or mineral-deficient animals. Clinical signs—including blindness, ataxia, and tremors—often mimic other diseases or plant toxicities, leading to delayed diagnoses. Studies indicate that a single battery can poison up to 20 calves, with lead persisting in the tissues of survivors for over a year, rendering meat and milk unsafe for consumption. This article highlights the critical need for vigilant pasture inspections and the prompt, proper recycling of lead-containing materials to mitigate financial losses and prevent unnecessary animal suffering.
