Investigators have found that a tainted milk incident in northwest China that killed three children and sickened 36 others appears to be a case of intentional poisoning and have detained a suspect.
The state-run China Daily newspaper said Monday that investigators found nitrite, an industrial salt that can be deadly, was added to fresh milk from two dairies last week in northwest China's Gansu province in order to harm people. A suspect in Pingliang city, where the poisoning took place, has been taken into custody, but the report gave no details.
China's worst food safety scandal in recent years involved fresh milk, infant formula and other dairy products tainted with the industrial chemical melamine. Six children died and more than 300,000 were sickened in the 2008 scandal.
