Recently, it was doubted that Dumex formula was tainted, since some parents have reported that their babies are suffering kidney stone. Shanghai quality inspection institution made investigation and reported that the Dumex formula did not containing melamine. It seems that this report can reduce parents' anxiety. And Dumex company disclaims on its homepage, which says that Dumex milk powder is safe. It is useless. Many parents do not believe it.
It is known that there are many matters could cause kidney stone, besides melamine. However, the goverment institition only tested these samples to confirm that whether it contained melamine. Maybe there is other ingredients cause kidney stone, such ascalsium exceeding safe value, antibiotics, and so on.
It should be confirmed that every index of qualified formula is OK so that people can believe the brand.
