Police in China have arrested a couple suspected of deliberately poisoning milk that led to the deaths of three children.
Thirty-six other infants became ill in China’s north-western Gansu province last week. Investigators found that nitrate had been added to fresh milk from two dairies. A man and woman have been detained. Those that died lived in the city of Pingliang and suffered nitrate poisoning; all the victims were under two years of age.
Authorities did not disclose a motive for the crime, but villagers near the farms cited competition between farmers as a possible reason.
China is still struggling to rebuild confidence in its food production, following the 2008 tainted-milk scandal that left six babies dead and 300,000 sick.
