What clinical sign is associated with maple leaf toxicity in animals?

Maple leaf toxicity, particularly in animals such as horses, is primarily associated with hematuria, which is the presence of blood in the urine. This condition arises from the toxic constituents found in wilted or dry maple leaves, particularly the presence of compounds that lead to oxidative damage to red blood cells. As a result, animals affected by maple leaf toxicity can experience hemolytic anemia, which manifests as hematuria due to the breakdown of red blood cells and subsequent leakage of blood into the urine.

Understanding the clinical signs associated with this toxicity helps in the timely diagnosis and treatment of affected animals. Hematuria is a critical indicator in veterinary practice that prompts further investigation into potential exposures to toxic substances like those found in maple leaves.
