I think this NPR article is too quick to put a positive spin on this. They have made a nice little story here with a happy ending. Farmers had blackened turmeric -> they used a random yellow die they found -> massive lead spike in everyone's bloodstream -> Americans came in with a xray gun and saved the day -> no more lead in the blood.
But if you ascribe even the slightest but of agency to any of the non-Americans involved, you have to wonder if this problem will come back.
