Methods Cadmium concentration of 1950 rice samples collected from Yunnan province in 2014 was determined by inductively coupled plasma mass spectrometry (ICP-MS). The metal pollution in milled rice was evaluated by single factor pollution index, and the metal health risk was assessed by nonparametric probability method. Results Cadmium concentration of 2.5% samples was exceeded the China health standards for food (0.2 mg/kg). The hazard quotient (HQ) of the health risk was higher than 1 for 97.5% and 99.5% exposure. Conclusion The accumulation of Cd in rice is a potential health risk to consumers of some areas in Yunnan province. Considering the potential health risk, it is necessary to implement yearly monitoring of Cd contamination in milled rice in Yunnan province.
