Abstract
A survey of 17,600 individuals in 20 counties in So. Carolina gives a goiter incidence of 3.8% compared to about 10 times that percentage in the goitrous states. An analysis of 15 So. Carolina vegetables gives high I contents as compared to analyses from other states by McClendon. The I content of So. Carolina potatoes averages 211 parts per billion, about twice the content of potatoes from Idaho. Maine, Michigan, Minnesota, and North Dakota. Iodine content of potatoes from the coast is less than from inland. Iodine analysis of various waters from So. Carolina is given. It is assumed that people eating fruits and vegetables from this state may reasonably expect not to have goiter.
