Tainted Milk From China
These are two sites from the World Health Organization that offer information on the melamine-contaminated infant formula and other dairy products that have affected over 40,000 children in China. Other people in other countries are beginning to be affected because China has exported these melamine-contaminated products to other countries.
The second site includes frequently answered questions on melamine.
According the information from the first WHO site, melamine was what tainted the pet food that killed so many pets in the United States in 2007.
