U.S. rice exports to Haiti, which account for the bulk of supplies of the country's key food staple, contain unhealthy levels of arsenic and cadmium, heavy metals that can increase risks of cancer and heart disease, according to a recent study by the University of Michigan.
Haiti is among the United States' top buyers of rice, alongside Mexico and Japan, and cheap imports are more affordable than local options in the Caribbean nation, the poorest state in the Western Hemisphere.
According to the study, average arsenic and cadmium concentrations were nearly twice as high in imported rice compared to Haitian-grown product, with some imported samples exceeding international limits.
Nearly all imported rice samples exceeded the U.S. Food and Drug Administration's recommendation for children's consumption. The study did not evaluate levels of toxins in other importing countries.
