While there are many benefits associated with eating chocolate, it’s hard to say whether you’d be getting the same benefits if your chocolate was tainted with toxic heavy metals lead and cadmium.

Unfortunately, this is the case for many popular brands we see on the market today (even “organic” brands). In fact, a great deal of the chocolate consumed around the world contains lead and cadmium, two heavy metals that are toxic to the body.

Negative Health Effects of Lead and Cadmium

In a study conducted by As You Sow, levels of cadmium and lead in 45 of 70 chocolate bar samples (including some organic brands) tested were found to be higher than what is considered safe in drinking water.

Both lead and cadmium are toxic metals that are unhealthy even at extremely low doses.

Lead is found in many places in our environment: air and drinking water, soil, dust, paint, cosmetics, contaminated herbal products from China, children’s toys, jewelry, ceramics, imported canned food, and many other sources (including chocolate).

Lead is toxic to the nervous system, liver, kidneys and reproductive system. Chronic exposure can lead to anemia, weakness, kidney damage, and even brain damage (1). “Lead exposure is associated with neurological impairment, such as learning disabilities and decreased IQ, even at very low levels. In fact, there is no safe level of lead for children,” said Eleanne van Vliet, MPH, As You Sow’s Environmental Health Consultant.

“As underscored by the Flint disaster, humans have contaminated our environment with lead, and now we must do everything in our power to protect ourselves and children, who are the most vulnerable of us, from every possible exposure,” said Sean Palfrey, MD, a paediatrician and Professor of Paediatrics and Public Health at Boston University School of Medicine.”Young children and pregnant women especially should avoid exposure to lead.”

Cadmium isn’t much better. Chronic exposure to cadmium can create serious problems in the kidneys, bones, and lungs, leading to conditions such as osteoporosis, heart disease and even cancer (2). As with lead, children are more susceptible to the ill-effects that long-term low doses of cadmium can have on the body over time.

“Lead and cadmium accumulate in the body, so avoiding exposure is important, especially for children,” explained Danielle Fugere, As You Sow President. “Our goal is to work with chocolate manufacturers to find ways to avoid these metals in their products.”

Why Are Heavy Metals Found In Chocolate?

One word: contamination.

While manufacturers claim that lead and cadmium are absorbed by the cacao plant in trace amounts and come from naturally-occurring sources, research claims otherwise.

An article published in Environmental Health Perspectives looked at the studies done by American, Nigerian, British, and Australian researchers. They concluded that only a small percentage of contamination is coming from the soil itself. The big contributor? The shipping and processing of cocoa products (3).

Another study published by As You Sow (the same people who conducted the heavy metals in chocolate study), found that lead and cadmium contaminate chocolate via the following routes (4):
– Soil contamination due to man-made pollution
– Direct application of pesticides and sewage sludge disposal containing lead and cadmium, as well as fertilizers containing cadmium
– Processing: fermentation, drying the beans, manufacturing (drying, refining, cinching), shipping, handling, packaging

According to As You Sow, the largest contributor to heavy metal contamination in chocolate occurs after the beans have already been harvested and dried. Shipment and manufacturing of cocoa and chocolate products is also a major contributor (5).

In the U.S., there is no set limit for these metals in chocolate, aside from California, where chocolate makers are required to put a warning label on their products if they contain more than 4.1 mg of cadmium per daily serving.

This is unlike the European Union, who has developed strict guidelines for cadmium exposure: no more than 0.10 mg/kg of cadmium in milk chocolate, and no more than 0.30 mg/kg of cadmium for darker chocolates.

A recent review published in 2019 pointed out a variety of different studies that looked into heavy metal concentrations in cacao and cocoa products (6).

One of the studies looked at in the review explained that processing methods accounted for increased concentration of heavy metals.

This also explains why milk chocolate might show up as having lower levels of heavy metals, as the percentage of cocoa powder in chocolate products is directly proportional to their corresponding lead and cadmium levels (7).

In addition, some studies have found that cadmium concentration in cocoa beans do not show any significant difference between cocoa cultivated under organic versus conventional production (8). 

Brands of Chocolate to Avoid

As You Sow laboratory-tested 70 chocolate products. Results showed that over 45 of them contained higher levels of lead and cadmium than would be safe in our drinking water.

Safer Chocolate Brands

The unfortunate reality is, is that most of the chocolate grown comes from soil that is contaminated with heavy metals. This goes for both organic and non-organic chocolate.

This, in addition to the fact that certain processing methods may increase heavy metal concentration in chocolate, makes finding safe chocolate quite difficult.

I have personally reached out to some companies to check for heavy metal contamination, but none of them have given me clear answers on whether their chocolate is free from these contaminants.

    So I would love to see a list of quality chocolates that don’t contain these harmful additives.

      I’ve contacted a handful of companies and none of them could give me a definitive answer. It was kind of like they were trying to hide that their chocolate may contain heavy metals. I’ve heard chocolate from Costa Rica is good, because the soil there is not tainted.

        I noticed most listed were dark chocolates. Did you test milk chocolate from the same companies? I prefer Sees and Dove chocolates, but both in milk chocolate. Curious why they would not be affected too? Thank you in advance for your time.

          Hey Kim – I didn’t do the testing myself, I reference the study in the article. Milk chocolate would also be affected, it would just have lower concentration because the chocolate in milk chocolate is very diluted.

      As stated in the article, I have not yet found a company that is heavy metal-free.

    Hi Carly,

    According to berkeleywellness.com, California’s limit is 4.1 mcg of cadmium.

    Cheers!

    According to this article by As You Sow, there are a few products that do not require warnings as to their lead and cadmium content: https://naturalrevolution.org/chocolate-contaminated-toxic-metals/

    Two I often see recommended for their safety and freedom from toxic heavy metals are: Endangered Species Natural Dark Chocolate (72% cocoa) and Ghiradelli Intense Dark Midnight Reverie (86% Cacao).

    Thanks!

          Hi Eli, unfortunately, no. I am not sure where you are reading Dark Midnight Reverie, but the Endangered Species Natural Dark Chocolate (72%) contains lead as outlined in the article (blue = contains lead).

            Thanks, Carly. I’m just looking at that same article by As You Sow: https://naturalrevolution.org/chocolate-contaminated-toxic-metals/

            It shows a few chocolate products that by their testing and determination do not require safety ratings for either cadmium or lead. I’m just trying to find a brand of dark chocolate that is relatively safe for my family to eat from time to time 🙂

          • Carly Fraser says

            May 8, 2020 at 3:24 pm

            Yes totally! I think one of the brands you mentioned does have lead in it though – the Endangered species brand!

    I have received replies from 2 companies that their chocolate is regularly tested and does not contain toxic levels of cadmium or lead: Righteously Raw, and Pascha.

    Great. Do you know if they provide test results to back that up?
