New kidney ailments baffle experts

Health experts are trying to find out the epidemiological reason behind the increasing number of kidney stone cases among children, the Ministry of Health said yesterday.

Dozens of infants have reportedly fallen ill after taking Dumex milk food, although on Tuesday the General Administration of Quality Supervision, Inspection and Quarantine said the company's baby food was free of melamine.

"But the parents are not happy with the official test result," said Jiang Yalin, the mother of a 20-month-old kid suffering from a kidney ailment. Jiang has organized a group of parents in Kaili, Guizhou, to seek compensation from baby milk food firms.
