A recent test by the U.S. Food and Drug Administration (FDA) concluded that the amount of detectable arsenic was too low in the rice and rice product samples to cause any immediate or short-term adverse health effects.
Dating back to September 2012, approximately 1,300 samples of rice and rice products were tested by FDA scientists. Infant and toddler cereals, pasta, grain-based bars, rice cakes, desserts and puddings were among the products examined. Beverages, including beer, rice wine and rice water were also among the samples tested.
Among the rice grain categories, the average levels of inorganic arsenic (the most toxic form of arsenic) ranged from 2.6 to 7.2 micrograms per serving, with instant rice at the low end of the range and brown rice at the high end. Among the rice product categories, of which there was a wide variety, the average levels of inorganic arsenic ranged from 0.1 to 6.6 micrograms per serving, with infant formula at the low end of the range and rice pasta at the high end.
