Arsenic is a chemical element present in the environment from both natural and human sources, including erosion of arsenic-containing rocks, volcanic eruptions, contamination from mining and smelting ores, and previous or current use of arsenic-containing pesticides.
Different types of arsenic
There are two types of arsenic compounds in water, food, air, and soil: organic and inorganic (these together are referred to as “total arsenic”). The inorganic forms of arsenic are the forms that have been associated with long term health effects. Because both forms of arsenic have been found in soil and ground water for many years, some arsenic may be found in certain food and beverage products, including rice, fruit juices and juice concentrates.
How does arsenic get into foods?
Arsenic may be present in many foods including grains, fruits, and vegetables where it is present due to absorption through the soil and water. While most crops don’t readily take up much arsenic from the ground, rice is different because it takes up arsenic from soil and water more readily than other grains. In addition, some seafood has high levels of less toxic organic arsenic.
Organic foods vs Non-Organic foods
Because arsenic is naturally found in the soil and water, it is absorbed by plants regardless of whether they are grown under conventional or organic farming practices.
Health risks associated with arsenic exposure
Long-term exposure to high levels of arsenic is associated with higher rates of skin, bladder, and lung cancers, as well as heart disease. The FDA is currently examining these and other long-term effects.
FDA recommended test for arsenic in foods
Yes, the FDA has been testing for total arsenic in a variety of foods, including rice and juices, through its Total Diet Study program since 1991. The agency also monitors toxic elements, including arsenic, in selected domestic and imported foods under the Toxic Elements Program, including those that children are likely to eat or drink, such as juices.
