Arsenic in Rice: Full Analytical Results from Rice/Rice Product Sampling - September 2012

Arsenic in Rice Main Page

For updated sampling results from May 2013, see Analytical Results from Inorganic Arsenic in Rice and Rice Products Sampling (PDF: 767KB).


On September 19, 2012, the FDA released the first analytical results of nearly 200 samples of rice and rice products collected since in the U.S. marketplace. The FDA is collecting and analyzing more than 1,000 additional rice and rice product samples, and will post additional data as results become available.

NOTES:

Sample results based on dry weight with the exception of rice beverage samples.

1ppb = parts per billion (microgram/kilogram)

2Some rice beverages have been marketed as “ricemilk,” a product name consumers could see in supermarkets and consumer materials. However, FDA’s regulations do not contain provisions for the use of the term "ricemilk." Therefore, in this document, the term “rice beverage” includes products that may be marketed as "ricemilk."

aND = Not Determined. FDA is attempting to determine the country of origin.

bTR = Trace. Result is between the detection limit and quantitation limit (see table below).

cServing size based on Reference Amount Customarily Consumed (RACC) per 21CFR 101.12 for each product category: 

  • Grains (e.g., rice) - 45 g (dry) - about 1 cup cooked rice (general population)

  • Breakfast cereal (e.g. rice cereal) – 30 g – about 1 cup (general population)
    Note: RACCs for dry infant cereal, ready-to-eat breakfast cereals, and uncooked hot cereal range from 15-40 g depending on density and intended consumer (i.e., infant). An average serving size of 30 g was used for all cereal samples except the infant cereals which used a value of 15 g to calculate the mcg inorganic arsenic/serving.

  • Snacks, all varieties, chips, pretzels, popcorns, extruded snack, et al (e.g., rice cakes) - 30 g - about 2 cakes (10-15 gm/cake)
    Note: rice cakes are mostly a puffed rice product, and serving size for larger rice cakes is typically labeled as 1 cake (10-15 g/cake). Mcg of inorganic arsenic/serving for rice cakes was calculated using the RACC for snacks (30 g) which results in a higher calculated amount of mcg inorganic arsenic/serving than using the labeled serving size. (general population) 

  • Beverages (e.g. rice beverage) - 240 ml (an assumption was made that 1 ml = 1 g for purposes of calculating inorganic arsenic per serving) - about 1 cup (general population)

d"Wild rice" is not actual rice. Wild rice comes from an aquatic annual grass (Zizania aquatic) bearing edible grain. 

eNS = Not Speciated - Sample 728648 not speciated because total arsenic value was less than quantitation limit. Sample 728651 not speciated because sample was moldy. Speciation not performed on noted rice beverage samples because total arsenic results were below the threshold level to require speciation.

fNC = Not Calculated. Value of mcg/serving not calculated either because speciation not performed (no inorganic arsenic value determined) or because the amount of inorganic arsenic in the sample was reported as "Trace" (between the detection limit and the quantitation limit).

gNR = Not Recorded - country of origin for processed products would not necessarily reflect the country of origin for the rice in the product.

Limit of Detection (LOD) and Limit of Quantitation (LOQ) - in ppb 
Note - actual limits may vary depending on the analytical portion used in the analysis. For inorganic arsenic (sum of AsIII and AsV), the limits are the sum of the individual species.
