Experimental hexachlorophene intoxication in young swine.

G R Robinson, D J Wagstaff, J J Colaianne

    American Journal of Veterinary Research
    |November 1, 1975

    Summary

    This study explored hexachlorophene (HCP) intoxication in swine as a model for human poisoning. Oral HCP administration in swine effectively induced central nervous system dysfunction, correlating with dosage.

    Area of Science:

    • Veterinary toxicology
    • Comparative pathology
    • Neurotoxicology

    Background:

    • Hexachlorophene (HCP) is a chemical agent with known toxic properties.
    • Understanding HCP toxicity in animal models is crucial for human health risk assessment.

    Purpose of the Study:

    • To evaluate swine as a model for hexachlorophene (HCP) intoxication, mimicking human poisoning.
    • To investigate the effects of topical and oral HCP administration on swine physiology and central nervous system function.

    Main Methods:

    • Swine were administered daily doses of hexachlorophene (HCP) via topical or oral routes.
    • Comprehensive assessments included central nervous system evaluation, hematology, serum chemistry, necropsy, and tissue residue analysis.

    Main Results:

    Related Experiment Videos

    • Oral HCP administration reliably induced intoxication in swine.
    • Topical HCP application did not consistently produce a toxic syndrome.
    • Observed signs and lesions, including incoordination and paresis, were linked to central nervous system dysfunction (status spongiosus).
    • Higher HCP dosages correlated with increased signs, lesions, mortality, and tissue residue levels.

    Conclusions:

    • Swine, particularly via oral exposure, serve as a viable model for studying hexachlorophene (HCP) intoxication.
    • HCP toxicity primarily affects the central nervous system, with dose-dependent severity.
    • Dosage is a critical factor influencing the manifestation and outcome of HCP poisoning.
