Salt Queen’s micro-enterprise produces four to five tonnes of product a day in peak season

Senegal is the largest salt producer in west Africa, harvesting almost half a million tonnes every year. Small-scale harvesters, who work in areas such as Lake Retba and Fatick, are responsible for about one-third of production.

However, many producers fail to iodise the salt. Nutrition International, a Canadian-based NGO that works to eliminate mineral and vitamin deficiencies in developing countries, organises co-operatives and provides harvesters with iodisation machines and training.
