It is also found in seafood, but this is the less toxic organic arsenic. Arsenic finds its way into food because it’s absorbed by the plant as it grows. Therefore, strategies to reduced arsenic contamination of rice should focus on reducing arsenic availability, such as through alternate wetting and drying while monitoring other redox-sensitive contaminants (Carrijo et al., 2018; Honma et al., 2016; Limmer et al., 2018a), or by selecting low arsenic accumulating rice varieties (Chi et al., 2018).
