High Quality Content by WIKIPEDIA articles! This timeline of the 2008 Chinese milk scandal documents how events related to the Chinese dairy products contamination by melamine unfolded. Complaints about kidney problems traced back to a brand of infant formula, subsequent discoveries of melamine contamination of liquid milk, and exported powdered milk of processed food products (using contaminated milk).
