An organic sweetener called organic brown rice syrup has been found to be the source of elevated levels of arsenic in some foods according to a new study by Dartmouth researchers.

Their findings are in the journal, "Environmental Health Perspectives" and says one infant formula sweetened with organic brown rice syrup had six times the federal limit for arsenic in drinking water. 

Jim Morris with the California Rice Commission says the Federal Food and Drug Administration should provide guidelines for arsenic content

MORRIS: "Help our farmers, our mills, and consumers understand the importance of arsenic in rice and rice products.  We want the expertise from the F.D.A…a science-based understanding of healthy food and this naturally-occurring element."
