    Aflatoxicosis caused steer deaths due to contaminated corn. Aflatoxin residues were found in kidney tissue, with liver lesions confirming the diagnosis.

    Area of Science:

    • Veterinary Toxicology
    • Animal Pathology

    Background:

    • Aflatoxicosis is a serious health concern in livestock.
    • Mycotoxin contamination in animal feed can lead to significant economic losses.

    Observation:

    • A group of crossbred feeder steers experienced unexplained deaths.
    • The feed ration included corn contaminated with 1,500 ng/g of aflatoxin.

    Findings:

    • Aflatoxicosis was diagnosed as the cause of mortality in the steers.
    • Residues of the mycotoxin, aflatoxin, were detected in the kidney tissues of affected animals.
    • Microscopic examination of liver sections showed pathological lesions characteristic of aflatoxicosis.

    Implications:

    • This case highlights the critical need for rigorous testing of animal feed for mycotoxins.
