Clean melamine residue

With the dairy products company Sanlu bankrupt and the chief culprits sentenced to death in the wake of the 2008 melamine scandals, many naively thought that domestic dairy producers would learn and behave, and that melamine would be thing of the past.

That is why, despite the initial boycott that almost ruined local dairies, consumers have returned and the Ministry of Agriculture has reported a "better-than-expected" recovery.

But that was prior to the re-emergence of melamine-contaminated dairy products on store shelves. Five companies were found to have used melamine-tainted materials that should have been destroyed in 2008.
