> ”Rather a large number of things are contaminated with heavy metals”
Sure, but usually it’s because products are grown in contaminated soil and “naturally” pick up traces from their environment. Pretty much all rice contains arsenic, for example, but the concentration varies significantly depending on where it’s grown and how it’s processed.
The turmeric problem is different because lead has been deliberately added during processing, and it’s been found in relatively huge quantities - as much as 2-10% by weight in some cases!
