If you’re a fan of Swiss chocolate, chances are you haven’t skipped Lindt’s famous chocolates.
But the renowned chocolatier is now at the centre of a controversy after acknowledging the results of a study that highlighted concerns over the presence of lead and cadmium in its “expertly crafted” confections.
Does this mean Lindt chocolates are no longer safe to eat? How has the Swiss chocolatier responded to these claims? Here’s a deeper dive into the controversy.
Allegations against Lindt
It all started when the Consumer Reports, an American non-profit released a study in 2022 on chemicals found in dark chocolates.
The organisation said it tested several dark chocolate brands but found
alarming levels of heavy metals such as lead and cadmium in Lindt’s products. It said that the premium Swiss chocolate contained astronomically high levels of lead in its Excellence Dark Chocolate 85 per cent Cocoa, and cadmium in its Excellence Dark Chocolate 70 per cent Cocoa.
The Consumer Reports warned that long-term exposure to even small amounts of heavy metals could pose a range of health risks across all age groups.
The study sparked outrage among US consumers, leading to a class action lawsuit against Lindt & Sprungli in 2023. Consumers alleged that the company’s claim of “expertly crafted with the finest ingredients” was mere “puffery”—a legal term for exaggerated marketing that no reasonable consumer would take seriously.
According to AFP, consumers from multiple US states, including Alabama, California, Florida, Illinois, Nevada, and New York, argued they paid a premium for Lindt chocolates, trusting they were getting high-quality, safe products. The lawsuit claims that Lindt breached state labelling laws by not disclosing the presence of heavy metals in its chocolates.
How has Lindt responded?
According to court documents accessed by US-based media group Nexstar, Lindt has admitted that “lead and cadmium are unavoidable in the food supply” and insisted that the trace amounts in its products were well within regulatory limits.
The company also defended its use of terms like “expertly crafted” and “finest ingredients,” arguing that they were simply promotional phrases, or “puffery,” not to be interpreted as literal promises.
This legal strategy aimed to get the case dismissed, but it only intensified the criticism.
Switzerland’s NZZ am Sonntag newspaper described Lindt’s approach as a “self-inflicted wound,” suggesting that the chocolatier had “dismantled its own promises of quality.”
In response, Lindt clarified that its puffery defence was a “technical” legal tactic, not an admission of substandard quality. The company reassured its customers, stating, “Our consumers can have full confidence in that.”
However, the Eastern District of New York court rejected Lindt’s request to dismiss the case, allowing the lawsuit to move forward.
Are Lindt chocolates safe to consume?
While heavy metals like lead and cadmium are naturally found in the environment, their presence in food products, including chocolates, can pose serious health risks if consumed in significant quantities over time.
Lead is particularly harmful, impacting nearly every system in the body and posing a serious threat to children’s health. According to WHO, high levels of exposure can cause severe damage to the central nervous system, with symptoms including unconsciousness, convulsions, and even death.
Furthermore, lead is linked to dyslexia, a learning disorder that affects reading and writing skills.
In adults, long-term exposure to lead can result in nervous system disorders, high blood pressure, kidney damage, weakened immunity, and reproductive health issues. It can also lead to developmental problems for pregnant women.
Cadmium, meanwhile, is classified as a carcinogen by the Centers for Disease Control and Prevention (CDC) and is associated with kidney damage and severe gastrointestinal problems, such as vomiting and diarrhoea after prolonged exposure.
So, does this mean we should stop eating chocolate?
In a statement, Consumer Reports cautioned that regular consumption of dark chocolate with high levels of heavy metals could pose significant health risks, so one should be cautious about eating it frequently.
“The risk comes with frequent consumption over time. Heavy metals are also in certain other foods, including many that are more nutritious and important to eat as regular parts of a healthy diet, such as carrots, sweet potatoes, and spinach. So it’s best to eat dark chocolate only occasionally,” the study advised.
