Article mixes a lot of unrelated food safety issues. Which mostly serves to confuse readers, or cause them to mix up unrelated issues. As for the arsenic in rice: rice tends to be a (natural) accumulator for arsenic. Which occurs in soils in varying amounts - some natural, sometimes increased by pollution. Lead in turmeric otoh, is from a lead-based colorant intentionally added to make the (prized) yellowish color more intense. Very different problems, with very different causes & solutions. (but on a side note: personally I would not mind if people found to have adulterated food with lead compounds, were hung on the nearest tree. Lack of knowledge be damned. A few example culprits hanged, and everyone in the trade would educate themselves quickly).
