Why does my ham look iridescent?

What gives sliced ham that iridescent sheen? The shiny, greenish, rainbow like color on sliced ham is a sign of oxidation that occurs when the meat is exposed to the metal on a knife or slicer. The nitrate-modified iron content of the meat undergoes a chemical change that alters the hams pigmentation.
