砷是一種天然的元素，廣泛存在于各種食品中，在大米中的含量較高。無機砷的毒性較大，攝入量過大會引起癌癥與皮膚受損。
新加坡農糧局提議將糙米中無機砷的限量定為0.35ppm。據(jù)了解，該限量與國際食品法典委員會的限量相一致。
部分原文報道如下：
The Agri-Food and Veterinary Authority （AVA） is seeking feedback from stakeholders （rice importers and food manufacturers） on proposed amendments to the Food Regulations concerning the maximum limit for inorganic arsenic in husked rice.
Maximum limits for incidental constituents, commonly termed “contaminants” are specified under the Food Regulations. Arsenic is a naturally occurring element, and is present in many foods due to absorption from the soil and water. In order to safeguard consumer health, maximum limits for arsenic in food are specified under the Food Regulations.
