BEIJING (Kyodo) Chinese-made frozen dumplings recalled after the pesticide-tainted products caused food-poisoning cases in Japan apparently went on to sicken steelmakers in China's Hebei Province, who were given the contaminated "gyoza" for free, company sources and employees said Saturday.

The products, made and recalled by Tianyang Food in Hebei, were delivered to employees of Tangshan Iron and Steel Co. for free from April to May last year, they said.

The steelmaker recalled the dumplings after some of the employees reported they were getting diarrhea and other symptoms of food poisoning, they said.
