Reducing Arsenic in the Human Food Chain


Researchers Janine Sherrier and Harsh Bais of the University of Delaware seek to reduce arsenic levels in rice by blocking uptake of the toxin.

Harsh Bais and Janine Sherrier of the University of Delaware's Department of Plant and Soil Sciences are studying whether a naturally occurring soil bacterium, referred to asUD1023 because it was first characterized at the university, can create an iron barrier in rice roots that reduces arsenic uptake.

Rice, grown as a staple food for a large portion of the world's population, absorbs arsenic from its environment and transfers it to the grain. Arsenic is classified as a poison by the National Institutes of Health and is considered a carcinogen by the National Toxicology Program.
