Unfortunately these tests are still $100+ per test. Assuming there are tens of contaminants you might want to test for, and hundreds of foodstuffs in a typical pantry, the cost is out of range of a typical American. I would like to see a government grant for cheap testing methods. Either covid-like test strips which are sensitive enough and can measure 10+ contaminants for mere cents, or a government test centre which will test for free anything you mail to them using an XRF gun (expensive kit, but can test one thing every 5 seconds or so, making the amortized cost very low)
