Turmeric is trending in the Hacker News Collective Conscious. It could have been any word. The news piece was "Indians caught using lead as food colorant".
I found a spice producer's site that contained some instructions of how to determine if it's adulterated [2]:
Metanil Test: To test for the presence of metanil yellow, place a pinch of turmeric powder in a test tube, add a few drops of strong hydrochloric acid, and violently shake it.
If the solution becomes pink, this indicates the existence of metanil. Consuming turmeric powder that is high in metanil will make you feel nauseated, create stomach problems, and cause food poisoning.
Lead Chromate Test: To test the presence of lead chromate in turmeric powder, mix a teaspoon of turmeric powder with water. It will instantly leach streaks of water-soluble colour into the solution, indicating the presence of lead chromate.

Typically, it's followed by something along the lines of "if only big Pharma/government would get out the way, we could have…
