Area of Science:

  • Veterinary Toxicology
  • Ruminant Pathology

Background:

  • Castor bean (Ricinus communis) is a plant known for its toxic properties.
  • Accidental ingestion of toxic plants in garden waste can lead to animal poisoning.

Observation:

  • Forty-five sheep exhibited clinical signs of toxicosis after consuming castor bean-contaminated garden waste.
  • Clinical manifestations included weakness, salivation, watery diarrhea, dehydration, mydriasis, and hypothermia.
  • Seventeen animals succumbed to the intoxication.

Findings:

  • Hematological findings revealed a high hematocrit.
  • Biochemical analysis showed elevated serum BUN, creatinine, phosphorus, CK, and AST.
  • Pathological examination identified severe gastroenteritis, cardiac hemorrhage and necrosis, hepatic necrosis, and acute tubular kidney necrosis.
