"Avoid This Coffee Machine" Experts Warn of Increased 'Cancer Risk' [Health Talk]

[Financial News] Research results have emerged suggesting that black plastic coffee machines may increase the risk of cancer, attracting attention.

The UK Daily Mail reported on July 30 (local time) that experts warned that black plastic might contain high levels of cancer-causing chemicals and flame retardants.

The key factor that can influence cancer development is the black plastic used as a material for coffee machines. This plastic contains 'carbon black' dye.

It contains a large amount of carcinogenic compounds called polycyclic aromatic hydrocarbons (PAHs). The International Agency for Research on Cancer (IARC) classified carbon black as a possible carcinogen (Group 2B) in 2020. This classification applies when carcinogenicity is confirmed in animal experiments, suggesting a possibility of causing cancer in humans, although there is insufficient evidence in human studies. Additionally, this plastic is a material frequently used not only in coffee machines but also in kitchen utensils. Various foreign media have been warning about its carcinogenic risks.

In this regard, brominated flame retardants (BFRs) and organophosphate flame retardants (OPFRs) used to protect products from electrical fires are also dangerous. According to a 2024 study in Chemosphere, exposure to products containing these substances at high concentrations can increase the risk of cancer and cause neurotoxicity and hormonal disorders. 

The problem is that if a coffee machine using these flame retardants is damaged or exposed to boiling water for a long time, carcinogens can dissolve and seep into the coffee. It is known that when carcinogens enter the body, they can cause cell damage and potentially lead to mutations that can develop into cancer.

According to a study published last April, tracking over 1,000 Americans for 20 years revealed that those with high blood levels of flame retardants had a 300% higher risk of dying from cancer compared to those with lower levels.

The U.S. environmental group 'Toxic-Free Future' science policy manager Megan Ryu criticized, "Companies continue to use toxic flame retardants in plastic electronic products, leading to unexpected toxic exposure," and emphasized, "We must reduce toxic plastics, transition to safer chemicals and materials, and put an end to the practice of keeping plastic ingredients secret." 

Meanwhile, experts recommend using coffee machines made of stainless steel or glass that are free of bisphenol A (BPA). They also emphasize regularly cleaning the machine and using filtered water.
