The arsenic level detected in the rice and rice product being imported to the U.S has no serious impact on public health.

The FDA official on his website posted that the arsenic level detected in more than 1,300 samples was too low to cause any harmful effect on the health of public.

Rice is particularly vulnerable to absorbing arsenic, a chemical element, because it’s grown in water. Rice and rice-based products such as cereal and baby foods were selected from retailers and analyzed. The study occurred after consumer advocacy groups raised concern that arsenic in rice threatened the health of consumers.

The FDA said it will continue its investigation, including looking into the potential for long-term health risks.

 Arsenic can be entered into the crops either through eroded rocks or volcanic eruptions. The chemical element can also be introduced into groundwater and soil by humans through mining and the use of pesticides.
