Why it matters

Wild flag iris grows in wet pasture edges; usually avoided but can be eaten when forage is short.

Signs of iris poisoning in alpacas

  • Drooling
  • Loss of appetite
  • Diarrhea
  • Colic or abdominal discomfort

Signs can appear within minutes (cyanide, cardiac toxins) or only after weeks of exposure (liver toxins). Many poisoned camelids are simply found dead, so prevention is everything.

What to do if your alpaca ate iris

  1. Move the herd away and remove any remaining plant material, clippings or fallen leaves.
  2. Call your veterinarian immediately, even if the alpaca looks normal. Say what was eaten, roughly how much and when.
  3. Bring a sample or clear photo of the plant to help identification.
  4. Do not give home remedies, oils or try to make the alpaca vomit unless your vet tells you to.
  5. Keep the animal quiet, in shade or shelter, with water available. Write down the time and every symptom you see.
  6. Check every other alpaca that had access, then remove the plant permanently (including roots).

Emergency: call your veterinarian immediately. If you cannot reach them, contact an animal poison control service (in the U.S., the ASPCA Animal Poison Control Center or Pet Poison Helpline; fees may apply). Bring a sample or photo of the plant.

About the plant

Iris is a flowering plant genus of 320 accepted species with showy flowers. As well as being the scientific name, iris is also widely used as a common name for all Iris species, as well as some belonging to other closely related genera. A common name for some species is flags, while the plants of the subgenus Scorpiris are widely known as junos, particularly in horticulture. It is a popular garden flower.From Wikipedia — “Iris (plant)”, licensed under CC BY-SA 4.0.
