The chart below shows the means over the eight years of testing our brown rice compared to the maximum levels (ML) set by CODEX. The mean inorganic arsenic (iAs) contents of LFF brown rice for each year are less than one third of the CODEX standard for ML 0.35 ppm of iAs in brown rice. Furthermore in 2018, the California Office of Environmental Health Hazard Assessment (OEHHA) established default natural background levels of iAs in brown rice at 0.17 ppm.

Inorganic Arsenic (ppm) by crop year

The 8-year average was 0.09 ppm, with a range of 0.01 – 0.24 ppm. As farming practices were similar between the eight crop years, variability across these years may be attributed to differences in weather patterns and the volume of different varieties grown in each year.

The tables below represent inorganic arsenic (iAs) content in different types of rice for the 2012 – 2019 crop years:

The 2020 crop harvest (planting starts Spring 2020) will be our 10th consecutive year of continued testing as part of our ongoing arsenic monitoring program.

We remain committed to invest time and resources in this testing plan to provide you with meaningful data. We will continue to collect and analyze samples across our product lines and from multiple crop years to ensure the reliability of our data. When it comes to understanding our products, we want to be sure. At Lundberg Family Farms, your health and safety is our primary concern.
