Toxicity
[change | change source]Zinc is a main part of U.S. pennies minted after 1982, and is toxic. Swallowing a penny, which is almost fully made of zinc, can cause damage to the stomach lining.[2] Coins are the most common eaten object in children, but are generally allowed to pass, unless the patient shows symptoms. [3]Zinc toxicity is commonly fatal in dogs, where it causes a severe hemolytic anemia.[4]
