Tanzania salt pans. Array of bags packed full of salt after being mined from salt pans (background). These salts pans are among several in and around the port of Bagamoyo on Tanzania's Indian Ocean coast. Tanzania is a major producer of salt in Africa, with tens of thousands of tons of salt produced annually. Salt producers range from large industrial operations to small, manual operations where the salt bags are filled by hand. In coastal areas, water is piped from the sea to evaporating ponds. Regulations require this salt to have iodine added to overcome iodine deficiency disease (IDD).
