Responding to published research showing high levels of heavy metals in commonly eaten food items, As You Sow began extensive independent laboratory testing of 42 chocolate products for lead and cadmium. We found that 26 of the chocolate products (~62%) contain lead and/or cadmium at levels in which one serving exceeds the California safe harbor level for reproductive harm. We filed notices with 16 manufacturers, including See’s, Mars, Hershey, Lindt, Godiva, Whole Foods, and others, for failing to provide required warnings to consumers that their chocolate products contain lead, cadmium, or both.
Lead and cadmium were found in popular chocolate products.
See the products we tested in the tables below.
No level of lead is safe for children. Lead exposure has been a significant public health issue for decades and is associated with neurological impairment, such as learning disabilities and lower IQ, even at low levels. “No amount of lead ingestion is ‘safe’ for children,” states Sean Palfrey, MD, a pediatrician and professor of Pediatrics and Public Health at Boston University School of Medicine. “Pregnant women and young children with developing brains in particular should avoid any ingestion of lead.”
Cadmium is also known to cause reproductive harm. Chronic exposure to cadmium has been to kidney, liver, and bone damage in humans. Children are more susceptible to exposure effects from low doses of cadmium over time. Companies are not doing enough to keep their products safe and below California’s safe harbor level for reproductive harm for these toxic heavy metals.
As You Sow, a consumer health protection organization, commissioned an independent state-certified laboratory to measure levels of lead and cadmium in 42 chocolate products available at retailers across California. The charts indicate whether, pursuant to test results, the product requires a warning under California’s Safe Drinking Water and Toxic Enforcement Act.
