WASHINGTON >> The Food and Drug Administration may consider new standards for the levels of arsenic in rice as consumer groups are calling for federal guidance on how much of the carcinogen can be present in food.
So far, FDA officials say they have found no evidence that suggests rice is unsafe to eat. The agency has studied the issue for decades but is in the middle of conducting a new study of 1,200 samples of grocery-store rice products — short and long-grain rice, adult and baby cereals, drinks and even rice cakes — to measure arsenic levels.
Rice is thought to have arsenic in higher levels than most other foods because it is grown in water on the ground, optimal conditions for the contaminant to be absorbed in the rice. There are no federal standards for how much arsenic is allowed in food.
Arsenic is naturally present in water, air, food and soil in two forms, organic and inorganic. According to the FDA, organic arsenic passes through the body quickly and is essentially harmless. Inorganic arsenic — the type found in some pesticides and insecticides — can be toxic and may pose a cancer risk if consumed at high levels or over a long period.
How much organic and inorganic arsenic rice eaters are consuming, and whether those levels are dangerous, still remains to be seen.
FDA Commissioner Margaret Hamburg says consumers shouldn’t stop eating rice, though she does encourage a diverse diet just in case.
“Our advice right now is that consumers should continue to eat a balanced diet that includes a wide variety of grains — not only for good nutrition but also to minimize any potential consequences from consuming any one particular food,” she said.
