The glutinous rice dumplings, or "zongzi," are wrapped in bamboo or reed leaves and shaped like pyramids, but some unscrupulous manufacturers are using copper-based chemicals to keep the leaves green.Something shy as a native Chinese living overseas with routine intergrity always heard bad food safty news from the mother land!
"The leaves dyed by copper sulphate or copper chloride contain metal elements which will penetrate into the zongzi and cause great damage to the health," food expert Shen Xiangkun was quoted as saying, backing a warning by the China Consumer Association.
"The worst zongzi contained 34 times more copper than the national standard!"
