Obviously there’s more detailed info out there. Here’s something from Consumer Report to chew on in the meantime:
How much arsenic is in your rice?
Consumer Reports’ new data and guidelines are important for everyone but especially for gluten avoiders
Published: November 2014
In late 2012 we released our original report on arsenic in rice, in which we found measurable levels in almost all of the 60 rice varieties and rice products we tested.
Our most recent testing and analysis gave us some new information on the risk of arsenic exposure in infants and children through rice cereal and other rice products. We looked at data released by the Food and Drug Administration in 2013 on the inorganic arsenic content of 656 processed rice-containing products. We found that rice cereal and rice pasta can have much more inorganic arsenic—a carcinogen—than our 2012 data showed. According to the results of our new tests, one serving of either could put kids over the maximum amount of rice we recommend they should have in a week. Rice cakes supply close to a child’s weekly limit in one serving. Rice drinks can also be high in arsenic, and children younger than 5 shouldn’t drink them instead of milk. (Learn the new rice rules about weekly servings.)

In 2012, we recommended that babies eat no more than one serving of infant rice cereal per day, on average, and that their diets should include cereals made from other grains. We did not find any reason to change our advice based on our new analysis. When we shared our results with the FDA and asked for comment, the agency reiterated its recommendation that everyone, including pregnant women, infants, and toddlers, should eat a variety of grains. And they pointed out that parents should "consider options other than rice cereal for a child’s first solid food.”
The trouble with arsenic
Arsenic has two chemical forms, inorganic and organic (the latter of which can be less toxic), and is naturally part of the minerals in the earth’s crust. (Note, here organic is a chemistry term and should not be confused with food sold as “organic.”) Arsenic also has been released into the environment through the use of pesticides and poultry fertilizer. (Chickens can be fed arsenic.) Therefore, it’s in soil and water. Rice tends to absorb arsenic more readily than many other plants.
Regular exposure to small amounts of arsenic can increase the risk of bladder, lung, and skin cancer, as well as heart disease and type 2 diabetes. Recent studies also suggest that arsenic exposure in utero may have effects on the baby’s immune system.
The USA Rice Federation says, “Studies show that including white or brown rice in the diet provides measureable health benefits that outweigh the potential risks associated with exposure to trace levels of arsenic.” Consumer Reports food safety experts believe those levels do carry a risk.
There is no federal limit for arsenic in rice and rice products. (The FDA has proposed a “action level” for arsenic in juice.) Since 2012, Consumer Reports has been calling on the FDA to set one. The agency told us: “The FDA’s ongoing assessment of arsenic in rice remains a priority for the agency. Last year, the FDA released what we believe to be the largest set of test results to date on the presence of arsenic in rice and rice products, and we are planning to release a draft assessment of the potential health risks associated with the consumption of arsenic in these same foods.”
