Toxicity to pets

Queensland nuts, also called Macadamia nuts, are harvested from Macadamia trees that were originally found in Australia. These trees are now also grown in the US (Hawaii, California, Florida), South Africa, Brazil, and many other countries with the nuts being sold widely in stores. Depending on the amount nuts ingested, clinical signs of severe lethargy, increased body temperature, vomiting, tremors, joint stiffness, and inability to walk (due hind limb weakness) may be seen. The toxic mechanism is unknown but can affect nerve and muscle function. Some dogs may also develop pancreatitis (inflammation of the pancreas) due to the high oil content of these nuts.
