WASHINGTON (September 6, 2013)—The U.S. Food and Drug Administration released a study Friday on arsenic in rice, and says consumers shouldn't worry too much about the levels of the carcinogen, but should vary their diets just in case.
The study the agency released of arsenic in 1,300 samples of rice and rice products is the largest to date looking at the carcinogen's presence in rice.
It found varying levels of arsenic.
The most was in brown rice and the least was in instant rice.
The FDA says the amounts are so small that rice is safe to eat, but it is still studying long-term effects of consuming rice.
The agency has long encouraged consumers to vary their diets to minimize risk.
Rice likely contains arsenic because it is grown in water on the ground, where the contaminant can be absorbed.
