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.

Children at greater risk

According to the National Institutes of Health (NIH), children are even more vulnerable to these chemicals. Whether it's through indirect exposure or mouthing plastic objects, the cumulative effect of toxins can have lasting impacts on brain and hormonal development.

Expert recommendations: What you can do

Health experts are advising consumers to take the following precautionary measures:
Avoid black plastic coffee machines, especially those made from recycled materials.
Switch to machines made from stainless steel or glass for safer alternatives.
Use BPA-free models to limit exposure to endocrine disruptors.
Clean your coffee machine regularly to remove any residual build-up.
Use filtered water to reduce mineral and chemical accumulation.
By making simple yet informed changes, coffee lovers can continue enjoying their daily brew without compromising their health.

Recap

The convenience of your daily coffee ritual may be hiding a health hazard. As research continues to uncover the risks of toxic compounds in household appliances, experts urge consumers to opt for safer, chemical-free coffee makers.
