The Ministry of Health says it's hard to determine whether hormones in powdered milk is the cause for a recent case involving three baby girls in central China's Hubei province.
The parents of the three baby girls were shocked to discover their daughters developing breasts. After a series of tests, they all suspect excessive hormones in milk powder is to blame. They say the girls had been fed the same batch of infant formula, produced by Syrutra, a famous Qingdao-based company.
Syrutra has posted a statement on its website declaring all their products are safe. The Health Ministry has instructed food safety authorities in Hubei Province to investigate the case.
