Not all chocolate made without the use of child labor or slavery carries the Fair Trade certified label. Things to look for:

• Single-source - Where chocolate comes from can often provide a clue as to whether slavery was used in its manufacture. For example, Central and South American countries are not known to have slave labor.
• Organic - Companies that strive for organic, sustainably grown chocolate are also growing their cocoa in a manner that protects workers from exposure to harmful chemicals. On the other hand, there is no guarantee that organic farms have other fair labor practices or do not use child or slave labor.
• Cooperative - Cooperatives are groups of small-scale farmers who work cooperatively; Fair Trade cerified cooperatives operate under standards that guarantee a minimum price to farmers, require fair labor practices, and prohibit the use of child or slave labor. Look up the name of the cooperative mentioned and see its reputation online.
