Coffee makers may contain cancer-causing toxins
Health researchers are raising alarms over black plastic coffee machines, commonly found in homes across the globe.
Recent studies suggest these appliances may expose users to dangerous chemicals, including those known to cause cancer and disrupt hormones.
Cancer risk linked to recycled black plastic
The concern centers around carbon black—a pigment widely used to give recycled plastics their sleek black appearance. While it may look stylish on your countertop, this color additive contains toxic compounds such as polycyclic aromatic hydrocarbons (PAHs).
In 2020, the International Agency for Research on Cancer (IARC) officially classified carbon black as a carcinogen.
These PAHs are not only heat-resistant but also lipophilic, meaning they can easily dissolve in hot liquids like coffee, making exposure through daily use more likely.
Fireproof, but at what cost?
To make coffee machines more fire-resistant, manufacturers often include brominated flame retardants (BFRs) and organophosphate flame retardants (OPFRs) in the plastic casing.
However, a 2024 study revealed that these flame-retardant chemicals pose serious health risks, such as:
- Hormonal disruption
- Increased risk of thyroid and breast cancer
- Brain development issues
- Infertility, especially in women
The research particularly highlighted damage to the female reproductive system, making it a critical concern for long-term users.
