A Chinese court has sentenced a former food plant worker to life in prison for poisoning frozen dumplings that made 10 people ill in Japan.
The incident strained Beijing-Tokyo relations just months before China hosted the 2008 Olympic Games, when millions of bags of dumplings were recalled and Chinese food products taken off Japanese shelves amid safety fears.
The official Xinhua News Agency said Lu Yueting, 39, was sentenced today by a court in the north-eastern city of Shijiazhuang.
Lu had been dissatisfied with his wages and, in late 2007 injected insecticide into several boxes of frozen dumplings to get attention from his managers.
The products were later sold in Japan and in the Chinese city of Chengdu, making at least four people ill.
Lu, detained in 2010 after more than two years of investigations, contaminated the dumplings with methamidophos, a type of pesticide, compounding widespread fears about the safety of Chinese food exports.
