Improved salt iodation methods for small-scale salt producers in low-resource settings in Tanzania

摘要

BackgroundUniversal salt iodation will prevent iodine deficiency disorders (IDD). Globally, salt-iodation technologies mostly target large and medium-scale salt-producers. Since most producers in low-income countries are small-scale, we examined and improved the performance of hand and knapsack-sprayers used locally in Tanzania.
