    Area of Science:

    • Veterinary Medicine
    • Toxicology
    • Animal Pathology

    Background:

    • Oak poisoning is a significant concern for cattle health.
    • Outbreaks can lead to severe clinical signs and mortality in affected herds.

    Purpose of the Study:

    • To describe two outbreaks of oak poisoning in cattle in South Africa.
    • To detail the clinical signs, pathological findings, and affected demographics.

    Main Methods:

    • Case description of two separate cattle herd outbreaks.
    • Clinical examination and post-mortem examination of affected animals.
    • Histopathological and histochemical analysis of kidney tissues.

    Main Results:

    • Two outbreaks affected 22/80 and 40/135 cattle, with high mortality in the second outbreak.
    • Young cattle under 2 years old were exclusively affected.
    • Key lesions included non-suppurative interstitial nephritis, cecal, and colonic edema and ulceration.

    Conclusions:

    • Oak poisoning poses a severe threat to cattle, especially young animals.
    • The observed pathological changes highlight the systemic toxicity of ingested oak.
    • Further investigation into histochemical properties of kidney pigment granules is warranted.
