That same chemical structure – six nitrogen atoms per molecule – would later become its curse. Part 4: The Dark Turn – The Melamine Scandal of 2008 By the early 2000s, melamine was everywhere. But then came the disaster that would forever stain its name. The Crime In China, dairy companies discovered a terrible shortcut.
