Your body needs a certain amount of copper, but too much copper is not good for you. Remember that the old adage, "If a little is good, more is better," is NOT generally TRUE, especially when it comes to certain nutrients, including copper.
Copper toxicity is a problem in the U.S. Often it's a result of copper water pipes in your home. It may also come from anti-fungal sprays used on vegetable and grain crops. Another source is meat, if the animal's food was supplemented with copper.
