Dairy giant the Yili Group yesterday recalled some baby formula products after 'abnormal' levels of mercury were found.
The firm said it issued the recall after the national food-safety watchdog made the discovery in its All Excellent line of milk powder on Tuesday.
The recall was made despite the lack of national standards on mercury content in milk powder, the firm said.
The problematic batches were produced between November and May. Yili said its other dairy products were untainted.
Workers of the Jiajiayue supermarket group in Yantai , Shandong province yesterday confirmed that they were told to remove All Excellent products from sale in e-mails from their company headquarters.
But several Jiajiayue outlets across the mainland yesterday said they had not heard about the recall and were still selling the products. Guan Jun, a blogger who is a former newspaper reporter, was the first to report the recall on his Sina microblog account yesterday morning, but did not identify the Yili Group.
