In 1998, UNICEF reported that Ivorian farmers were using enslaved children — many from surrounding countries.[28] A 2000 BBC documentary described child slavery on commercial cocoa farms in Côte d'Ivoire.[2][29] In 2001, the US State Department estimated there were 15,000 child slaves in cocoa, cotton, and coffee farms in Côte d'Ivoire,[30] and the Chocolate Manufacturers Association acknowledged that child slavery is used in the cocoa harvest.[30]
