The chocolate industry was made aware these abuses in 2001. The Chocolate Manufactures Association pledged to eliminate slave and child labor from cocoa production. Many of Hershey's competitors, like Mars and Cadbury, have begun to implement policies to purge child labor from their supply chains. Cadbury, its parent company Kraft Foods, Blommer Chocolate Company, and Mars Inc., and about half a dozen other major chocolate manufactures, have all agreed to use cocoa certified by independent monitors.
