We have updated our arsenic testing page with results of our 2016 crop. Overall, the levels remain in the range we have seen over the six years we have been monitoring inorganic arsenic in our products. At 0.090 parts per million, they are slightly below our 6 year average of 0.093 parts per million. There have been no new recommendations coming from any regulatory agencies, domestically or internationally, and the consensus remains that US-grown rice fits well as part of a balanced diet for the general population.

The FDA issued draft guidance in 2016 to limit the levels of inorganic arsenic in rice used in infant cereal to address potential developmental concerns. At the same time, they advised pregnant women to eat a variety of grains and for infants to be given a variety of fortified infant cereals. The average levels in our rice over the past six years of testing continue to fall below the FDA’s draft guidance.

Codex, the international agency tasked with providing guidance for foods in international trade, issued its guideline for levels of arsenic in white rice in 2015, and our brown rice products continue to test at less than half this level. The European Food Safety Authority’s standards for levels of inorganic arsenic in rice products have been in place since January 2016, and our average level of inorganic arsenic over the past six years falls below all of those standards, including the most stringent baby cereal level of .100 parts per million.

Lundberg Family Farms continues to engage with farmers, academic and regulatory communities, as well as our colleagues in the food industry, to look for ways to reduce the levels of this naturally occurring element even further.We take pride in our food safety and we continue to work to bring you relevant information.

We support consumers’ right to know about the food they are eating, and remain committed to transparency about the food we provide. We have published arsenic-testing results for our crop for the past six years. We provide a link to information on arsenic that includes peer-reviewed research studies, as well as straight-forward answers to questions about arsenic in general and Lundberg-specific products.

Thank you for continuing to share your thoughts and concerns with us. We value your feedback as it helps us to focus on the things that matter to you. You can always reach us with your suggestions and comments at info@lundberg.com, or call (888) 215-2958.

The Science

There is growing consensus regarding the levels of inorganic arsenic in rice, and the potential impacts on human health. We continue to update our Resource Library to provide more in depth information for our consumers who are interested in learning more. In addition, we have summarized much of the scientific information below to provide an overview for consumers, and included references to the studies for your convenience.

Arsenic Mode of Action

Despite being one of the oldest known toxins, the scientific community still has not uncovered the specific mode of action of arsenic. At present, research suggests that arsenic at low levels found in rice is not a direct acting agent, but rather a co-respondent1. This means that other factors such as genetic predisposition, absence of vital nutrients such as selenium or folate, or co-existing contaminants such as smoking, must also be present for health risks to occur2.

International Standards

In 2019, the Codex Alimentarius Commission (Codex) adopted a standard ML of 350 ppb for brown rice (husked rice).

Effective January 2016, The European Safe Food Authority (EFSA) implemented standards for the Maximum Level (ML) of inorganic arsenic in rice products sold in the European Union. These standards are 250 parts per billion (ppb) in brown rice (husked rice) or parboiled rice, 200 ppb in white rice (polished rice), 300 ppb in rice crackers and rice cakes, and 100 ppb in rice destined for the production of food for infants and young children3.

In July of 2014, the Codex Alimentarius Commission (Codex) adopted a standard ML of 200 ppb for white rice (polished rice)4.

Scientific Assessment

On April 1, 2016, the U.S. Food and Drug Administration (FDA) released its scientific assessment of arsenic in rice. In this assessment, the FDA set a guidance level of 100 ppb for infant rice cereal, which is consistent with the EFSA standard that went into effect in January 2016. The FDA also advised pregnant women to eat a variety of grains and for infants to be given a variety of fortified infant cereals. It also continued its advice to the general population that rice should be eaten as part of a balanced diet with varied grains.5

Soil Levels

Naturally occurring levels of arsenic in US soils range from 1.1 mg/kg to 97 mg/kg, averaging 7.2 mg/kg. There is good evidence that these levels have not measurably changed over the past 50 years that they have been measured.6


The FDA suggests the best way for consumers to reduce the presence of inorganic arsenic in rice is to cook rice with a high volume of water and drain the excess water7. This method can reduce from 40 to 60 percent of the inorganic arsenic content, depending on the type of rice. While reducing the arsenic content, this method can also reduce the nutritional value of rice. Brown rice has the least nutrient loss using this method.

Another method that has been widely discussed to reduce the presence of inorganic arsenic in rice is to rinse before cooking. However, the FDA’s research shows that this method has minimal impact on inorganic arsenic in the cooked grain, but substantially reduces some of the key nutrients from the rice, particularly in white and parboiled rice.8

We are committed to providing great-tasting and healthy rice and rice products to our consumers, and will continue our efforts to understand and address this topic. We will continue to share our findings with you as we move forward, and provide information from the scientific community to assist you in making informed decisions about your food choices.
