What condition is associated with Fumonisin consumption in horses?

Fumonisin is a mycotoxin produced by certain molds found on corn and other grains. In horses, the consumption of fumonisin has been specifically associated with equine leukoencephalomalacia (ELEM). This condition is a severe neurological disease that leads to the degeneration of the white matter in the brain, resulting in symptoms such as incoordination, disorientation, and, in severe cases, death.

Horses are particularly sensitive to fumonisin, and ingesting contaminated feed can disrupt normal brain function, highlighting the toxicity of this mycotoxin. The link between fumonisin and ELEM has been well-established in veterinary research.

In contrast, equine influenza, colic, and equine West Nile virus are related to different etiologies. Equine influenza is a viral infection, colic refers to abdominal distress which can have various causes, and equine West Nile virus is a mosquito-borne viral infection. Therefore, understanding the specific risks associated with fumonisin helps horse owners and caregivers prevent serious health issues in horses.
