"Arsenic in rice occurs at such low levels that it poses no short-term health threat, Food and Drug Administration says, although it is still studying long-term effects. The arsenic in rice is thought to come from water on the ground, which is where rice is grown."
"WASHINGTON -- The Food and Drug Administration says consumers shouldn't worry too much about levels of arsenic in rice — but should vary their diets just in case.
The agency released a study Friday of arsenic in 1,300 samples of rice and rice products, the largest study to date looking at the carcinogen's presence in that grain. Consumer groups have pressured the FDA to set a standard for the amount of arsenic that can be present in rice products.
The study shows varying levels, with the most arsenic in brown rice and the least in instant rice. Infant cereal and infant rice formulas are also at the low end of the spectrum."
