In February, the government launched a national 10-day overhaul in the dairy industry and vowed to track down and destroy all leftover dairy products from the 2008 scandal.
During that investigation, 22 domestic dairy companies were found to have sold products containing the toxic chemical, which is used to make plastics and is associated with kidney stones in infants.
"The short-term solution didn't work well," Wang said, citing the latest occurrence of such products.
In response, the national food safety office said on Friday that it would restart a nationwide overhaul of milk powder, including its source, manufacturing, storage and sales.
