Via Yahoo Health News :

" Intentional poisoning was behind the tainted milk that killed three children and caused 36 others to become ill in China's northwestern Gansu province last week, state media reported Sunday night, adding to the woes of the country's maligned dairy industry.

Local investigators in Pingliang city said they had arrested suspects in connection with the nitrate-laden milk that caused 39 people to seek hospital care last Thursday, Xinhua news agency said. It did not give details on the suspects' identities or motives.

Nitrate, which is used to cure meat, has no use as a milk additive, the official China Daily newspaper cited a health bureau official as saying."
