A recent study conducted by INRAE, in collaboration with SOLEIL Synchrotron, the Lariboisière Hospital in Paris, and CNRS, has revealed a worrying reality: titanium dioxide (TiO₂) nanoparticles were detected in 100% of animal milk samples (whether cow, donkey, or goat milk, organic or conventional, fresh or powdered) and in 83% of infant formula samples, regardless of age group or type (organic vs. conventional) (Food Safety).
Even more alarming, TiO₂ was also confirmed in breast milk, collected from 10 volunteers in the Paris area. The number of particles varied significantly between samples — some containing up to 15 times more TiO₂ than others (EurekAlert!).
The concentrations are striking: animal milk contained between 16 and 348 million particles per liter, while infant formulas contained between 6 million and 3.9 billion particles per liter (Food Safety).
Despite the fact that the food additive E171 (titanium dioxide) has been banned in France since 2020 and in the EU since 2022, these contaminations suggest that sources of exposure are not limited to food. It is highly likely that exposure also comes from cosmetics, medicines, toothpaste, packaging, industrial environments, traffic, or soil.
The study calls for further research to identify the crystalline form, particle size, and possible toxicological effects.
