We do test rice for arsenic levels. The FSANZ standard is 1mg per Kg or 1 part per million and all our rice meets or is lower than this standard. The rice we supply to manufacturers of baby foods tests at 0.1mg per kg which is equivalent to 100 parts per billion. However not all our rice suppliers can ensure they meet this 0.1mg per kg requirement so our retail rice can be higher than 0.1mg per kg. However it is always lower than 1mg per kg.
It depends on where the rice is sourced and when there are droughts in Australia we source organic rice from Thailand.
While I would stress that any rice sold in Australia has to meet FSANZ criteria, it would seem that any rice inevitably contains levels of arsenic due to use of irrigation. As you know rice uses a lot of water to grow which is the main reason rice is one of the foods with the highest levels of arsenic. Rain-fed rice can be the best alternative, however it is very dependant on whether there is enough rain and is not the most reliable way to grow rice.
Not all overseas grown rice is higher in arsenic than Australian rice as arsenic levels in rice have a lot to do with pollution levels, industrial chemicals etc. I think I need to write a blog post about this issue to discuss in more depth.
