A recent scientific paper that concluded imported rice was heavily contaminated with lead has been suddenly withdrawn by its author. Natural News has confirmed from the author, Monmouth University Chemistry Professor Tsanangurayi Tongesayi, that the “scientific paper” is recalled until further notice.
The paper found that some sources of rice, including rice from China, were contaminated with as much as 12,000% more lead than allowed under current safety limits for children.
The story was widely published across the media, including Natural News. Its findings, after all, were consistent with many other findings about the contamination of foods grown in heavily polluted countries. So no one thought the conclusions might be in doubt. When we hear about “scientists” conducted metals analysis in foods, we tend to think they know what they’re doing, right?
The authors themselves discovered worrisome discrepancies on “scientific papers,” when they sent the samples to a third-party lab for verification. Why the Tongesayi team did not conduct third-party lab verification before announcing the results has not been explained.
Analysis machine somehow produced flawed data
According to their own announcement about their findings:
We measured the levels of lead in rice that is imported into the U.S. using XRF and the data was validated using a NIST1568a reference sample. Lead levels ranged from 5.95 +/- 0.72 to 11.9 +/- 0.6 mg/kg and the calculated Daily Exposure amounts were significantly higher than the Provisional Total Tolerable Intakes for all age groups.
Translation: What they’re basically saying is that they found lead at levels of 6 to 12 ppm in rice. But as you’ll see below, these numbers are completely wrong.
2012 tests from Consumer Reports reveal roughly 1,000 times LOWER levels of lead in rice
Here’s another clue worth considering in all this. In 2012, Consumer Reports published results of its lead analysis of 223 brands of rice. They also measured arsenic and cadmium in rice.

It sounds like the Tongesayi team made a very large mistake in their reporting. To read this article in full, click on the link below.
