How vets treat it

Immediate x-ray to locate the object followed by the removal of the metal piece or coin to prevent further absorption and severe anemia.

Why it's dangerous

When zinc-containing objects enter the acidic stomach environment, the metal breaks down and is absorbed into the bloodstream, leading to the destruction of red blood cells and potential organ failure.

Toxic compound: Zinc

Good to know

Ingestion of even a single zinc penny can be fatal without therapy; common sources include galvanized hardware and diaper rash creams containing zinc oxide.
