BEIJING -- No harmful chemicals were found in Chinese dumpling exports involved in a food poisoning incident in Japan, said China's quality watchdog on Thursday.

The General Administration of Quality Supervision, Inspection and Quarantine said tests conducted on two batches of dumplings on Thursday morning show no trace of pesticide remains, such as phosphorus.

At least 10 people in Japan's Hyogo and Chiba prefectures reported stomach ache, vomiting or diarrhoea after eating the dumplings, according to Japanese media.

Tests had been carried out on raw materials like ginger and cabbage used in the dumplings before exportation, which showed the products safe for eating, according to the administration.

The administration said it has demanded the producer of the dumplings, the Tian Yang company in north China's Hebei Province, recall all products in and on the way to Japan immediately.

Local public security forces were invited to join the investigation, while China will send experts to Japan for cooperation in resolving the issue, said the administration.
