First Aid & Prevention

First 30 Minutes

  • • Rinse the animal's mouth with clean cool water if large quantities of the plant were recently ingested.
  • • Remove all remaining plant material from the animal's environment to prevent further consumption.
  • • Monitor the animal for unusual gastrointestinal distress, lethargy, or allergic reactions for 24 hours post-exposure.

Contact Vet Immediately

  • • If the animal exhibits persistent vomiting, diarrhea, or lethargy within 24 hours of ingestion.
  • • If a very large quantity of the plant was consumed by a small pet (cat, small dog) or young/immunosuppressed animal.
  • • If the animal has pre-existing gastrointestinal conditions or known plant allergies prior to ingestion.

Prevention

  • • Never intentionally feed this plant to any companion or livestock animal, as it is not approved for feed use.
  • • Keep potted or harvested Cretan oregano out of reach of unsupervised young pets and livestock.
  • • Accurately identify this plant to avoid accidental mixing with approved animal feed crops.

Treatment & Prognosis
