Current opinion on the role of post-harvesting and cooking on arsenic mobility in rice grain, its surmounting risk towards human and domestic livestock with sustained management

• Arsenic (As) contamination in paddy and consequently the dietary system is an emerging global threat to human health. The harvesting, post-harvesting and cooking procedures of rice in Bengal delta further involves the use of As tainted groundwater which results in a concomitant increase of As levels in sunned, parboiled, and cooked grains, respectively. Inorganic arsenic (iAs) causing potential health risks is therefore high (appx. 90 %) due to the daily rice consumption. This study sheds light on higher As accumulation, distribution and assimilation during parboiling (24 %) and cooking processes (34 %) using As-tainted water, culminating additional As burden in cooked rice. Rice grain mediated health risk has displayed a concern level of 5 according to “Severity Adjusted Margin of Exposure” value. This study also takes heed of the domestic livestock exposed to As toxicity through contaminated fodder, resulting in contaminated animal by-products which initiates further longer lasting deleterious impacts on the society.
