The widespread use of children in cocoa production is controversial, not only for the concerns about child labor and exploitation, but also because, as of 2015, up to 19,000 children working in Côte d'Ivoire, the world's biggest producer of cocoa,[1] may have been victims of trafficking or slavery.[2] Most attention on this subject has focused on West Africa, which collectively supplies 69 percent of the world's cocoa, and Côte d'Ivoire in particular, which supplies 35 percent of the world's cocoa.[3] Thirty percent of children under age 15 in sub-Saharan Africa are child laborers, mostly in agricultural activities including cocoa farming.[4] It is estimated that more than 1.8 million children in West Africa are involved in growing cocoa.[5] Major chocolate producers, such as Nestle, buy cocoa at commodities exchanges where Ivorian cocoa is mixed with other cocoa.[6] In 2013-2014, an estimated 1.4 million children aged 5 years old to 11 years old worked in agriculture in cocoa-growing areas, approximately 800,000 of them engaged in hazardous work, including working with sharp tools and agricultural chemicals and carrying heavy loads.[7][8]
