How Do Lead and Cadmium Get Into Chocolate and Protein?

Cadmium (Soil Uptake)

Cadmium is absorbed directly through the root system of cacao trees growing in volcanic, mineral-rich soils (common in South and Central America).

Lead (Post-Harvest Drying)

Lead does not typically enter through the root. Instead, wet cocoa beans dried on the ground or by roadsides attract lead-contaminated airborne dust and exhaust.
