© 2015 Institute of Food Technologists®.It is well known that arsenic (As) exposure, particularly to inorganic species (i-As), has adverse effects on humans. Nowadays, the European Union (EU) has still not regulated the maximum residue limit of As in commercial samples of rice and rice-based products, although it is actively working on the topic. The European Food Safety Authority (EFSA) is collecting data on total arsenic (t-As) and i-As from different rice-producing regions not only from EU countries but also from other parts of the world to finally set up this maximum threshold. As Iran is a rice-producing country, the aim of this work was to evaluate the contents of t-As and i-As in 15 samples of Iranian white, nonorganic, and aromatic rice collected from the most important rice-producing regions of the country. The means of t-As and i-As were 120 and 82 ¿g/kg, respectively. The experimental i-As mean in Iranian rice was below the Chinese standard for the i-As in rice, 150 ¿g/kg, and the Food and Agriculture Organization of the United Nations (FAO) limit, 200 ¿g/kg. Therefore, Iranian rice seems to have reasonable low i-As content and it is safe to be marketed in any market, including China and the EU.
