Selenium in Foods Purchased or Produced in South Dakota

Abstract

ABSTRACT Selenium contents of 222 foods obtained in east‐central South Dakota are presented, the best sources being foods of high protein content, such as: meats; South Dakota cheeses; semolina products; breads; breakfast cereals prepared from soybeans, hard wheat, or oats; poultry and eggs; and some seafoods. Average values from this study are generally lower than those reported for similar foods from Canada, higher than those reported from Washington, DC, and considerably higher than those reported from Ohio. A study of milk samples from eight processing plants over the state, gave an overall average and standard deviation of 61 ± 12 μg/L. Values were highest in December and lowest in May.
