Arsenic In Rice Products

September 21st, 2012

Consumer reports has recently released an article pretaining to the amount of arsenic found in rice products avaliable in US food markets. Arsenic not only is a potent human carcinogen but also can set up children for other health problems in later life.

“In virtually every product tested, we found measurable amounts of total arsenic in its two forms. We found significant levels of inorganic arsenic, which is a carcinogen, in almost every product category, along with organic arsenic, which is less toxic but still of concern. Moreover, the foods we checked are popular staples, eaten by adults and children alike. No federal limit exists for arsenic in most foods, but the standard for drinking water is 10 parts per billion (ppb). Keep in mind: That level is twice the 5 ppb that the EPA originally proposed and that New Jersey actually established. Using the 5-ppb standard in our study, we found that a single serving of some rices could give an average adult almost one and a half times the inorganic arsenic he or she would get from a whole day’s consumption of water, about 1 liter.”

A link between the location of the rice grown for the particular consumer product and the level of arsenic reported has been found, showing that rice that was obtained from India, Thailand and California contains lower levels.

Here are some examples of grocery products that contain lower levels of aresnic: 365 Everyday Brand Organic Thai Jasmine White rice, Martin Brand Long-Grain Enriched, Trader Joe’s White Basmati, and Dogeut’s Brand Enriched Long-Grain.

Arsenic levels were detected in infant cereals also, typically consumed between 4 and 12 months of age. Among the four infant cereals tested, we found varying levels of arsenic, even in the same brand. Gerber SmartNourish Organic Brown Rice cereal had one sample with the highest level of total arsenic in the category at 329 ppb, and another sample had the lowest total level in this category at 97.7 ppb. It had 0.8 to 1.3 micrograms of inorganic arsenic per serving.

So what’s a parent to do? To reduce arsenic risks, they recommend that babies eat no more than 1 serving of infant rice cereal per day on average. And their diets should include cereals made of wheat, oatmeal, or corn grits, which contain significantly lower levels of arsenic, according to federal information.

According to federal data, some infants eat up to two to three servings of rice cereal a day. Eating rice cereal at that rate, with the highest level of inorganic arsenic we found in our tests, could result in a risk of cancer twice our acceptable level.

For children and pregnant women, risks are heightened. Keeve Nachman, Ph.D., a risk scientist at the Center for a Livable Future in the Johns Hopkins Bloomberg School of Public Health, says, “The more we learn about arsenic’s additional effects on the developing brain, the more concerned I am by these levels of arsenic being found in infant and toddler rice cereal.”

Consumers Union believes a standard for arsenic should be set for rice, and industry should accelerate efforts to reduce arsenic levels in rice. They should also develop types of rice that take up less arsenic, and use rice with the lowest possible arsenic in products for young children, such as infant rice cereal.

The following table summarizes guidelines for arsenic limits:

To find out more about what Consumers Union is doing on the subject and to get involved, go to ConsumersUnion.org/arsenic. On the international stage, a group advising the World Health Organization is meeting in 2014 to consider proposed arsenic standards for rice. Limits of 200 ppb (inorganic) for white rice and 300 ppb (total or inorganic) for brown rice are under discussion.

Dr. Miller’s Comment: This is another area that serves to educate us but we should not be alarmed.  I am quite sure that this has been in rice all along.  Now that we know the source of higher content, we should use that information to select products that are lower (hence placing pressure on producing products that are lower) and limit daily intake as described above.
