While we do produce rice domestically, imports from Asian nations (predominantly China) have far higher concentrations because the paddies are often contaminated with runoff from factories (like the ones that make electronics). We only test a small portion of the imported rice and because of the concern for Chinese origin, the rice is often routed through other countries to give a false impression of the country of origin. The major packagers and product manufacturers typically get supplies from a variety of sources and they're blended in the process so you can never be sure where the rice originated.
