Researchers map cadmium in cacao: 'The problem isn't as bad as we thought'

Cadmium naturally occurs in the soil of much of Latin America's cacao farms, and is absorbed by the plants. With EU regulations restricting the amount of cadmium allowed in chocolate imports, it is important for farmers to know where they can grow cacao that is fit for the global market. Researchers have compiled a map that aims to address this challenge.
