According to news, at least 6,200 babies were sick nationwide and 4 were killed because those milk powders tainted with the melamine.
Anyway, I did some research about melanine. Melanine is a a non-alimentary chemical which causes kidney stones. If you add this to milk and other food, it gives the appearance of higher protein levels, but it is very harmful to our health.
So, say no to these milk products.
