    Cadmium -Cd- , a kind of heavy metal pollutant, can enter the food chain though soil, dust, and crops. As a staple crop in China, rice can easily enrich Cd from soil, which can represent a health risk to consumers. Cd concentration in soil shows obvious heterogeneity in China. Cd concentration in rice is over the limit in some regions of China, due to the geological environment or soil pollution. At present, remedying polluted soil, screening low-accumulation material, and processing polluted rice have been developed to deal with Cd contamination. This paper summarized the present situation of cadmium contamination in rice and soil, analyzed the main factor of Cd enrichment in rice, reviewed the control technology of Cd contamination, and provided suggestions on Cd contamination research.
