Veterinary notes and prevention

The toxic mechanism is not fully understood. Chocolate-coated macadamias combine two toxins and warrant faster intervention.

Prepare the information your vet needs

  1. For Macadamia Nuts, report the exposure route: Eaten as nuts, in cookies or in trail mix. Tell the clinic the time, possible amount and your pet's species and approximate weight.
  2. Photograph the packaging, ingredient list or plant if safe. Do not handle contaminated material without protection or delay the call to identify it perfectly.
  3. Keep other animals away from the source. An animal may appear normal before signs develop; do not wait for symptoms or calculate a home 'safe dose'.
  4. Follow the clinic's transport instructions. Do not give food, medicines or home remedies unless instructed, and take packaging with you if available.
