Microplastics Found in
100% of Human Placentas
A landmark study examining 62 placental specimens found nano- and microplastics in every single sample — raising urgent questions about what babies are exposed to before birth.
The Findings
What the Researchers Discovered
Scientists at the University of New Mexico, in collaboration with Baylor College of Medicine, developed a highly sensitive technique to extract and measure plastic particles from human tissue. Using pyrolysis gas chromatography mass spectrometry — a method that can detect plastics at concentrations far too small to see — they analysed placental tissue from 62 participants.
The result was unambiguous: every single placenta contained measurable quantities of plastic. Concentrations ranged from 6.5 to 685 micrograms of plastic per gram of tissue, with an average of 126.8 µg/g. That is not a trace amount — it represents a meaningful accumulation of foreign material at the maternal-fetal interface, the barrier through which a developing baby receives all its nutrients.
Polyethylene — the same plastic used in food packaging, bottles, and cutting boards — was the most prevalent polymer found, accounting for 54% of all plastics detected. It was present in nearly every sample tested.

The science
The plastics detected most frequently in placentas — polyethylene and PVC — are the same materials found in conventional plastic cutting boards, food storage containers, and kitchen utensils.
Every time a plastic cutting board is used, microscopic particles shed directly onto food and are ingested. For pregnant women especially, reducing plastic contact in the kitchen is one of the most actionable steps available.
This study doesn't prove that kitchen plastics caused placental accumulation. But polyethylene is the dominant plastic found — and it is also the dominant material in conventional kitchen cutting boards. The case for switching is straightforward.
The Titan Haus solution
Shop the cutting board →The Titan Haus cutting board is made from medical-grade titanium — a material that does not shed particles, does not harbour bacteria in surface cuts, and has been used in clinical and surgical environments precisely because it contributes nothing to what it contacts.
Zero plastic. Zero shedding. Every meal.
