Emergency

Signs & symptoms

  • Sudden depression and loss of appetite
  • Jaundice
  • Dark urine (sometimes)
  • Collapse and death

Related symptom guides: Red or Dark Urine.

What causes it?

Chronic over-supply of copper (cattle minerals, goat products, copper boluses) or low molybdenum.

Risk factors

  • Feeding cattle/goat minerals or extra copper

How vets diagnose it

Blood liver enzymes, liver copper levels.

Treatment

Emergency vet care; some treatments exist but prognosis is guarded.

Do not wait to see if it improves. Camelids hide illness, and by the time signs are obvious the problem is often advanced. Call your veterinarian.

Prevention

  • Use camelid-formulated minerals only
  • Do not add copper without liver testing

Background

Copper toxicity is a type of metal poisoning caused by an excess of copper in the body. Copperiedus could occur from consuming excess copper salts, but most commonly it is the result of the genetic condition Wilson's disease and Menke's disease, which are associated with mismanaged transport and storage of copper ions. Copper is essential to human health as it is a component of many proteins, but hypercupremia can lead to copper toxicity if it persists and rises high enough.From Wikipedia — “Copper toxicity”, licensed under CC BY-SA 4.0.
