Chinese judicial authorities will begin the trial Tuesday of a man accused of lacing "gyoza" dumplings with a toxic chemical that led to high-profile food poisoning cases in Japan about five years ago, the Japanese Embassy in Beijing said Friday.

The cases sparked concern among Japanese consumers over the safety of food imported from China.

Ten people in three families, in Chiba and Hyogo prefectures, showed symptoms of poisoning after eating frozen dumplings produced at a factory of Tianyang Food in Shijiazhuang in Hebei province between December 2007 and January 2008.
