A U.S. company says its baby milk powder is safe and did not cause kidney stones in Chinese babies.
A Chinese newspaper had reported that at least 20 families claimed their infants developed kidney stones after consuming Wyeth products, Agence France Presse reported.
"At this point, there is no clear evidence showing that these ailments have any link to Wyeth products," the company said in a statement posted on its China Web site Monday. The company said its products have been cleared by Chinese inspectors and said it would cooperate in finding the cause of the kidney stones in the babies.
Similar allegations prompted Chinese authorities to investigate the domestically produced milk powder of Danone Dumex, a unit of French food giant Danone. The company was cleared by China's product-quality regulator, AFP reported.
Last year, milk products contaminated with the industrial chemical melamine sickened about 300,000 infants and killed six.
