Children as young as five years old harvest cocoa in Ghana for candy giant Mars, Inc., an investigation by CBS News uncovered.

Mars, which makes popular chocolates like M&M’s and Snickers, had put plans in place to stamp out child labor from its supply chain by 2025. The chocolate-maker has touted lists of thousands of children it has rescued from cocoa plantations and put back in school, CBS reported. But the outlet’s investigation found that some of these children are still working in the fields.

A cocoa field supervisor for the Virginia-based chocolate-maker, who had previously been involved in making the lists, anonymously told CBS that “almost every data” used to write up the lists “is cooked… or is not accurate.” 

Some of the names on the lists were of children who don’t exist, CBS found. Others worked in the fields before and after school.

One of the children on the list, 15-year-old Munira, has worked in the cocoa fields for two-thirds of her life. She was visited by field supervisors last year and handed a backpack with school supplies. A year-and-a-half later, however, no one had checked on whether she actually went to school.

She told CBS that her family doesn’t have money to send her, or her brother, to school.

Another child nearly lost fingers when using a machete blade to open cocoa pods, CBS reported. U.S. human rights lawyer Terry Collingsworth, who filed a proposed class action against chocolate makers alleging consumer fraud, told the outlet that Mars is “telling the public that we’re rehabilitating this kid, and then they’re cynically coming here and just checking a box and the kid is back working the next day.”

Ghana and neighboring Côte d’Ivoire together produce nearly 60% of the world’s cocoa every year. The U.S. Bureau of International Labor Affairs estimates that 1.56 million children are engaged in child labor on cocoa farms in the two countries.

Mars is privately held. The company issued a statement in response to the report saying: “Mars unequivocally condemns the use of child labor. It has no place in our supply chain, and we are fully committed to helping to eradicate it.

“We are now urgently investigating the claims made in the broadcast and are ready to take appropriate action against any supplier found not to have met our expectations laid out in our Supplier Code of Conduct.”
