Introduced into milk, it can help conceal fraudulent dilution with water. Melamine-contaminated milk can lead to kidney failure in infants. [20] An additional 10,000 cases were reported from the provinces by 27 September. [32], Urinary calculi specimens were collected from 15 cases treated in Beijing and were analysed as unknown objects for their components at Beijing Institute of Microchemistry using infrared spectroscopy, nuclear magnetic resonance, and high-performance liquid chromatography. [113][114], The scandal led to an erosion of trust in locally produced infant formula and from then on, many Shenzhen residents and parallel traders travelled across the border to purchase powdered milk from Hong Kong shops. [citation needed], In the United States of America, which was otherwise unaffected by the scares, the US distributor of White Rabbit candies recalled the product when samples found in Hartford showed traces of melamine.
