BEIJING (AP) — A cancer-causing toxin linked to mildewed cattle feed has been found in baby formula in China, an official said Monday, the latest quality problem to plague the nation’s dairy industry since a 2008 tainted formula scandal that caused six babies’ deaths.

Aflatoxin was found in five batches of Nanshan Bywise brand formula made last year by Hunan Ava Dairy Industry Co. in Hunan province’s Nanshan city that were being sold in Guangzhou, said a man surnamed Gong from the Guangzhou Administration of Industry and Commerce General Office.
