First Aid & Prevention

First 30 Minutes

  • • Remove any remaining plant material from the mouth of the exposed individual if recently ingested
  • • Rinse the mouth thoroughly with clean, cool water to eliminate residual plant debris
  • • Monitor for 1-2 hours for any signs of unexpected discomfort or allergic reaction

Contact Vet Immediately

  • • Persistent vomiting, diarrhea, or lethargy develops within 24 hours of ingestion of large quantities of the plant
  • • The exposed individual shows signs of an allergic reaction (hives, facial swelling, difficulty breathing) after contact or ingestion
  • • Any other unusual or prolonged symptoms develop following exposure

Prevention

  • • No specific toxicity-related prevention is required, but limit access if your pet excessively chews non-food plants to avoid mild digestive upset
  • • Keep dried pampas grass decorative arrangements out of reach of young children and teething pets to prevent ingestion of large amounts
  • • Avoid planting in areas where livestock regularly overgraze to prevent consumption of excessive quantities that could cause non-toxic digestive irritation

Treatment & Prognosis

  • • Provide supportive care only, including access to fresh, clean water and small, bland meals if mild gastrointestinal upset occurs
  • • No targeted antidote is required as the plant contains no known toxic compounds
  • • Treat allergic reactions with standard antihistamine or emergency care as recommended by a medical or veterinary professional

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Cattle: No documented toxic risk; large ingestion may cause mild, non-toxic gastrointestinal irritation
Sheep: No reported toxic effects associated with ingestion of this plant
Rabbits: Safe for consumption in moderate quantities as part of a varied forage diet
Confusion Risk

The following plants look similar and may be confused:

Purple Pampas Grass Cortaderia jubata
Visually nearly identical to common pampas grass; key difference is its purple-pink flower plumes compared to the cream/white plumes of C. selloana, and it is also non-toxic
Ravenna Grass Saccharum ravennae
Often mistaken for pampas grass due to tall stature and feathery plumes; it is smaller in overall size and has narrower, more grey-green foliage, and is also non-toxic
