Human blood levels of selenium are reported to correlate somewhat with soil concentrations of the element (94). In addition, human ingestion of selenized vegetables and grain has resulted in signs of selenium toxicity (146). Ingestion of rice contaminated with cadmium from the effluent of a mining operation was hypothesized as the etiological factor in Itai-Itai disease in man (32). 

In large areas of the world, the soils contain very little selenium in forms that can be taken up by plants. Crops produced in these areas are, therefore, very low in selenium. A selenium (deficiency in livestock is a serious problem. A deficiency causes a form of muscular dystrophy in younger animals and poor reproductive qualities in the adult animals. For prevention, sodium selenate or sodium selenite, sometimes augmented with vitamin E. is added in proper proportions to feedstuffs Some areas, including the Plains and Rocky Mountain states in the United States have soils that are rich in available selenium. Tn regions like these, selenium toxicity is a problem. The situation is particularly senous in Arizona, California, Montana, Nevada, New Mexico, and South Dakota.
