A wide variety of toxins cause diseases in the horse and are investigated routinely by veterinarians and veterinary pathologists to identify the cause of illness and death. A complete investigation involves performing a thorough necropsy and requires macroscopic and microscopic examination of lesions and a variety of laboratory testing to obtain an accurate diagnosis. The identification of gross lesions by equine practitioners is often the first step in formulating a diagnostic plan. This article provides a description of selected common toxins producing detectable gross lesions in horses in North America. The article is useful to equine practitioners and veterinary pathologists investigating a toxicology-related death.
