A high-end organic chocolate company in Ashland is recalling 40,000 pounds of bars, bricks and drops because of high levels of lead in the products. The raw organic cacao from which the recalled chocolate was made came from a single supplier in Ecuador in a region of volcanic soils. He said company officials are planning to travel to Ecuador to examine the possibility that high lead content in the soil might be responsible for the test results. Dagoba, founded in 2001, has built a reputation as a manufacturer of high-end chocolate, sold through specialty and organic foods stores.
